Gone were the old romantic notions of wild drug orgies and heavily flavored dreams, but I didn’t regret them, because the truth was much better.

—Emily Hahn, “The Big Smoke,” The New Yorker, February 15, 1969

I arrived back in Bangkok flush with excitement, having made valuable contacts with collectors and antiques dealers and even managing to bring home a piece for my collection. My arrival was on a Monday in May, and I knew the Southeast Asian Ceramics Museum was closed on Mondays, but it was the middle of Bangkok’s torrid hot season and Roxanna usually went to the museum even on her day off just to escape the heat. I called her as soon as I walked out the airport doors and toward the taxi queue.

Roxanna’s cheery hello was just what I was hoping to hear—it emboldened me to invite myself over under the pretext that I could tell her about my trip. In truth I was craving a pipe after the long flight from Amsterdam. The feeling was not unpleasant. It was excitement for something I was looking forward to, like the giddy anticipation one feels at the prospect of a hearty meal after a day of going without food. Roxanna said she would call her driver and arrange to leave the university and go home immediately. I was traveling with a single bag but would have gladly lugged two or three suitcases over that narrow causeway to Roxanna’s house if there was going to be a pipe waiting for me. I got into a cab and told the taxi driver where I needed to go.

Back on the old floorboards, my pores open and oozing sweat for the first time in ten days, the whole whirlwind of a trip felt like a dream from the night before. Roxanna listened to my stories and was wowed. “You took an opium tour of Europe!” she laughed. “I’m jealous!”

But there was a problem. Over the course of half an hour, Roxanna rolled ten pipes for me and I eagerly smoked them, but they had no effect on me. I explained to her that Hoorde’s opium had been very drossy and that, having smoked the morphine-laden stuff constantly while in Europe, I probably needed more of her subtle chandu than usual to feel anything. I also told her that I hoped she wouldn’t get tired of my company, because I would need a daily session for a week or so in order to taper off my usage. Then my heart sank when Roxanna told me that she had to leave town and would be gone for a week.

“A whole week?!” I exclaimed. “What am I going to do?”

The idea of not smoking opium for a week seemed tragic. It wasn’t that I feared withdrawal. In Europe I had noticed hay fever–like symptoms and mild headaches a couple of times when Hoorde was slow to offer me a pipe. Not that I couldn’t manage it, of course—it was just that going a week without opium would be like enduring a week with a head cold. As my mind skittered about for a solution, I remembered that I could roll proficiently and there was no reason why I couldn’t smoke alone. “What if I were to buy a week’s worth of chandu from you?” I asked Roxanna.

“Sure. Why not? How much will you need?”

Taking a break from smoking, I counted out drops into a spare medicine bottle that Roxanna had on hand. The amount was supposed to be enough for twenty pipes a day, which would be much more than I needed since my plan was to smoke just enough chandu to comfortably wean myself off Hoorde’s dross. I twisted the dropper cap tightly onto the little brown bottle and then zipped it in my overnight bag with my razor, toothbrush, and deodorant. Even in the totally unlikely chance that I was stopped and searched, no policeman would ever guess what that little bottle contained. If questioned, I could always say the iodine-colored liquid was some traditional herbal remedy—perfectly plausible since they were very popular in Thailand and often came in unmarked packaging. I had no doubt that I would be believed if somehow I had to resort to this story.

I didn’t have the money with me to pay Roxanna for the chandu, but she waved this information away as though she were trying to dispel a bad smell. “Oh, come on. Just pay me when you can.”

Back at my apartment, I took the bottle out of my bag and put it in the refrigerator. I left the rest of the bag unpacked and, after having a hot shower, climbed into bed. Among other things, opium is the perfect cure for jet lag. I spent a wonderful night reliving my journey to Holland and France and, while I didn’t get much real sleep, I got up the next morning feeling refreshed.

I had a week’s worth of email to catch up on as well as some light work—a synopsis for a guidebook to Cambodia that I had been asked to update—which took me most of the day to finish. By late afternoon there was a nagging angst in my stomach. I thought of the bottle of chandu that I’d left in the fridge after coming home from Roxanna’s the night before. Hours in the chilled air would have made the liquid thick and rich. In my mind’s eye I could see the chandu slowly dripping from the dropper into the little wok … and then it struck me that my wok for evaporating chandu was packed away in a box somewhere. I was also lacking a working pipe—all were with Willi or Roxanna. The antique paraphernalia at my apartment hadn’t been used for many decades at the very least; pieces would need hours of modification before I could smoke.

This realization set me to thinking. Until now I had never even contemplated smoking in my apartment. By keeping opium at a safe distance I had been able to rationalize my smoking in the name of research—and the infrequency of my smoking was an important part of that rationalization. How could I justify smoking in the name of research if my behavior was no different from that of a common addict? I sat and stared at my computer screen until it went black. The screen saver suddenly launched a parade of images that glided to and fro. They were photos of some of my most prized pipes and lamps. A splendid little idea came into my head, causing me to smile and nod.

I set about gathering paraphernalia to form a layout—one that would be very different from the previous two working layouts I had put together. The one at Willi’s had taken years to assemble and was a work in progress, like the Chamber itself. It was meant to electrify emotions and evoke feelings of time travel back to a more elegant era. There was no way to outdo the Chamber layout in terms of opulence or the harmonious nature of its matching paraphernalia. Conversely, the one I had put together for Roxanna was durable and had a reliable functionality that was necessary for somebody who was going to smoke daily for years. Of course, when building both layouts I had kept the rarest pieces to myself. I would not, for example, have thought to use my pipe with the sugarcane stem because there were very few such pipes in existence.

But if only I would be smoking from the pipe—and for only one week—there was little worry about anything getting damaged. I knew how fragile my accoutrements were and how best to handle them. With this in mind, I decided that my personal layout should be a platform for experimentation that allowed me to do things I’d never done before. I had a full week to try out pieces that were too fragile to travel, and because my collection was all there in my apartment, I could dig out whatever I needed to put any theory to the test. When questions or ideas had come up at Willi’s or Roxanna’s, I sometimes didn’t bother to jot them down and then forgot them altogether, my train of thought severed by conversation. Alone in my apartment I would have a notebook and pen at my side at all times. I would turn the exercise of reducing my opium intake into a windfall of knowledge.

By 10 P.M. I was on the mat. It was a Cambodian woven-cane affair, about ten by twelve feet, that I had long ago carried back from a trip to southern Laos. The mat had been rolled up and propped in a corner for years and would not lie perfectly flat on my living room’s wooden parquet floor, but that was not a worry. I placed a large rectangular rosewood tray inlaid with mother-of-pearl in the center of the mat. This would be my layout tray. I then spent nearly an hour selecting and symmetrically arranging various boxes, tools, a lamp, and two smaller metal trays upon the larger tray. The mother-of-pearl patterns on the layout tray were mostly floral but punctuated with birds and butterflies. There were also depictions of four vases filled with bouquets of four types of flowers, which in Chinese culture represented the four seasons (winter—plum blossom; spring—peony; summer—lotus; fall—chrysanthemum).

Besides the depictions of flowers and insects, bits of opalescent nacre had been painstakingly cut into straight pieces as thin as kite string and buried into the rosewood. These lines divided the layout tray into sections—and were meant to be used as a diagram for whoever was setting up the tray. Using these patterns to guide me, I looked for accoutrements sized to perfectly fit within the mother-of-pearl delineations. The most obvious of these was a rectangle in the very center of the layout tray that marked a space for the lamp tray. Once I had finished arranging, the paraphernalia neatly conformed to the pearly schematic, allowing the flowery symbolism to show through.

Taking an idea from the Chamber, I brought from my bedroom a vintage gooseneck desk lamp and placed it on the mat at one end of the layout tray so the light would shine straight down on the accoutrements. On top of the mat where I would lie, I spread out a Burmese sarong of metallic green silk. I then folded a smaller length of silk into a square to use as a cushion atop the block-like porcelain pillow. As I am right-handed, I would lie on my left side facing the tray. Behind me were a bottle of mineral water, my notebook and pen, and, of course, the opium smoker’s scepter: a back scratcher. When everything was in place I lit the lamp.

Smoking opium alone was something I’d never done before. Sure, there were times when Roxanna catnapped while I was learning to roll, but other than that, smoking had always been a social event for me. Being alone with my thoughts was something I did after the session had concluded.

In his 1882 book, Opium-Smoking in America and China, H. H. Kane, who spent years interviewing opium smokers in New York City, stated, “I have never seen a smoker who found pleasure in using the drug at home and alone, no matter how complete his outfit, or how excellent his opium.” But Kane never met Jean Cocteau, who was born seven years after Kane’s book was published, and who said, “Smoking à deux is already crowded. Smoking à trois is difficult. Smoking à quatre is impossible.”

On that first night I found I was somewhere between these two opinions. Smoking fine chandu made me animated and chatty—as it did everyone I had ever smoked with. But smoking alone turned out not to be such a solitary activity after all. In the same way that I’d noticed I could vividly recall entire conversations immediately after sessions—while lying alone in bed—I was delighted to learn that I could also effortlessly imagine conversations while I was rolling. I first noticed this while concentrating on preparing a pipe. I imagined Roxanna making one of her usual remarks about the way I was letting the chandu evaporate without stirring: “Stir it or it’s going to burn.”

This should not be mistaken for “hearing voices.” There was no sensation of an audible noise—Roxanna’s remark was clearly in my mind. It was just that opium seemed to sharpen my imagination, for music as well as voices. I’m one of those people who often have songs playing in their heads—sometimes the same song for days on end. I don’t hear the song constantly; it comes and goes until some other tune takes its place. While smoking in a silent room I soon noticed that opium amplified these songs, making them crystal clear and impossible to ignore—now and then to the point that I had to turn on my stereo or get online and listen to some other piece of music, just to “change” the song playing in my head.

Of course, I’m no expert on the subject. Perhaps this is all nonsense and these non-aural songs and conversations were caused by some wrinkle on my brain. I don’t know. But my solo opium-smoking sessions were enjoyable from the start and, if some lonely people drink alcohol for the company it gives them, I can say that smoking opium alone also afforded me an imagined companionship that in time I would find preferable to the company of real people.

I was adamant that my plan to smoke just enough opium to taper off from the dross habit I’d formed in Europe go as scheduled. I was strict with myself, keeping a record in my notebook of how many pipes I smoked. That first night I smoked fourteen pipes and then promised myself that each subsequent night I would reduce the dosage by two. Every pill that I rolled would be made with no more than seven drops of chandu, ensuring that they would be about equal in size. I did not rush to finish the session but instead drew it out over nearly three hours. Between preparing pipes and smoking I passed the time examining a group of tools and accoutrements that I had lined up on the mat around the layout tray.

The largest of these items was a porcelain stand for pipe bowls, about eight inches high and shaped like a miniature chest of drawers. Two levels of horizontal surfaces were pierced with a total of five holes, each about the size of a quarter. Upon these holes rested clean pipe bowls sitting at the ready in case I needed to replace a dirty, dross-filled bowl with an empty one. The mystery of this whimsical little piece of opium furniture was a sixth hole, twice the size of the other five and positioned on a vertical surface, front and center on the piece. If this were really a miniature chest of drawers, this mystery hole was situated where a round mirror should have gone, but there was no mirror, just a hole and an empty, boxlike space in the porcelain behind it. A small, rectangular porcelain lid capped the space behind the round hole. The bowl stand was not unique. I had seen several others in various collections—although most bowl stands of this type were missing the aforementioned lid. What was this vertically positioned hole for? What purpose did it serve? The question had long bedeviled me.

Other collectors were convinced that the round hole had once framed the face of a clock, and that the space behind it would house the clock’s workings. It was an interesting idea, but on close examination of the bowl stand it just didn’t make sense. The space was too small even for an old-fashioned pocket watch to fit into it. Some collectors had pointed out that clocks were status symbols in old China, reflecting the modernity of their owners, and this was true. It was also true that a clock was handy to have while smoking, especially since opium could make time seem to slow down or speed up, depending on how much experience one had with the drug. Yet I was still unconvinced by the clock theory.

I owned four examples of this type of bowl stand, and so I placed one of the little porcelain mysteries at the foot of my layout tray. I then put pipe bowls on four of its five horizontal holes. The bowls I chose for this were some of my most colorful, and that first night I spent an hour gazing admiringly at this wonderfully incongruous piece of drug paraphernalia—an almost kitschy creation that could have been mistaken for Grandma’s vintage toothbrush holder—but which in fact was crafted to make an opium smoker’s messy vice more convenient and orderly.

The following night I began my session at the same time as the first. The tray was still arranged; I had simply slid it under my coffee table, put the bottle of chandu back in the fridge, and rolled up the cane mat. Once the session was well under way and I had smoked six pipes, I began once again to contemplate the porcelain bowl stand. Its odd configuration seemed as mysterious as ever.

Then, after my twelfth and last pipe of the night, I pushed the porcelain pillow aside and rested my head on the folded bolt of silk. Instead of going to bed, I decided to simply turn off the electric lamp and allow the oil-fed flame of the opium lamp to burn itself out, my slumber bathed in its diminishing glow. Lying supine, my whole body was relaxed and drifting like a raft on a placid sea, when suddenly an idea hit me with such force that it seemed to light up the room. It was nothing short of a revelation, and I knew instantly that I had solved the mystery. I sat up and turned the electric lamp back on and went into my bedroom to look for a white cotton T-shirt. When I found one that I didn’t care about, I used the lamp-wick scissors to cut the shirt into gee-rags—the small, doughnut-shaped cloth gaskets that when moistened form an airtight seal between the pipe bowl and the metal fitting on the pipe stem known as the saddle.

My mind was sharp and clear, and I sat on the mat working at my task until I had cut a handful of gee-rags, making a small pile of the curling cloth gaskets. Then I lifted the little lid from the porcelain bowl stand and stuffed the gee-rags into the space behind the vertical hole. The natural clinginess of the cotton kept the gee-rags bunched together and not a single one fell from the hole. Then, using two fingers, I reached into the vertical hole and pinched a gee-rag. When I pulled, it came out as easily and neatly as a tissue being plucked from a box of Kleenex. This made perfect sense! What would a smoker most likely need when changing from a dirty bowl to a clean one? Not a damned clock—but a fresh gee-rag, of course! I was so elated by my discovery that I hopped up from the mat and strutted around the room with my arms raised high.

To the layman my little discovery may sound like the height of useless arcana, but opium paraphernalia is full of these diminutive mysteries, bits of knowledge buried and forgotten like so many pieces of driftwood beneath the surface of a sandy beach—and each small mystery solved brought me that much closer to being the expert on my favorite subject.

My experience that second night was repeated twice more during my week of smoking alone. It felt as though the opium itself was giving me insight, guiding me and illuminating my path as I diligently worked to unlock its secrets.

It wasn’t until later that I remembered reading about the so-called hop-head hunch—uncanny powers of the mind attributed to opium smokers in American underworld lore. The phenomenon was recorded by Jack Boyle in an anonymously written essay in The American Magazine in June 1914. While relating his story of being an opium-addicted criminal in turn-of-the-century San Francisco, Boyle told of his own experiences with opium-induced revelations: “In the underworld there is a species of foresight termed ‘hop-head hunches.’ They are regarded with superstitious awe the country over.”

In Jack Black’s memoir of crime and opium smoking in western America and Canada of the same period, he, too, experienced a similar revelation when the solution for cracking a problematic safe came to him while smoking opium.

So, you ask: Was the hop-head hunch a bunch of hopped-up hooey?

“The Eureka Hunt,” an article in the July 28, 2008, issue of The New Yorker, asked a question with its subtitle: “Why do good ideas come when they do?” The story explained how relaxation, not concentration, is what allows the brain to have sudden bursts of creative insight—the same reason that solutions to problems seem to come to us while we are taking hot showers or during the minutes just before drifting off to sleep. Opium seemed to bring on these “eureka moments” with an amazing frequency.

Although my opium-induced revelations were the highlight of my week of weaning, I was also glad to learn how easy it was to get off the dross. After just over a week of smoking an ever-decreasing dosage of Roxanna’s opium, I “fasted” for five days to see if I could handle the withdrawal. Days three and four were uncomfortable—it felt as if I had a nasty cold—but by day five I was on the mend. I called Roxanna and made arrangements for a visit the following weekend, and for the next two months my smoking was limited to weekends.

Since turning forty, birthdays were something I did my best to ignore, but in mid-July 2007 I used the occasion of my forty-fifth birthday as a reason to bring home another quantity of chandu. Roxanna protested mildly when I told her my plan to spend my birthday smoking alone, but she, too, had been impressed by the little discoveries I’d made during my week of solitary research. She consented to sell me some, and so I measured out half a bottle drop by drop in front of her, counting in advance the hours and days that I would spend riding my magic carpet high above Chinatown.

Money was no longer a problem. By this time I had found a novice collector in Las Vegas whose hunger for antique paraphernalia was matched by his wealth. The collector was looking for tools to make two complete layouts and was willing to pay hundreds of dollars for each piece. Roxanna allowed me to use her PayPal account to receive the payments, so the cash went directly to her. In the past I had been adamantly against selling anything from my collection, but I came to realize that I owned plenty of duplicate tools because I was in the habit of buying items even if I didn’t need them—as long as the price was right. Now this strategy was paying off. I was able to sell for $200–$500 pieces that had originally cost me $20–$50. I now had more than enough money to pay Roxanna for her opium. I put the half-full dropper bottle in a small paper bag with the logo of a local hospital and took the subway home, buzzing with the feeling that I was about to take a long-awaited vacation to some wonderful and exotic locale.

My move to Bangkok’s Chinatown predated my interest in collecting antique opium-smoking paraphernalia by a couple of years. Once I started collecting, I began asking antiques merchants if they knew where Bangkok’s old opium quarter had been located. None that I talked to seemed to know. “Chinatown,” they said vaguely, forcing a smile to indicate that was all they knew.

One day I stumbled across an old-style antiques shop—more of a junk shop compared to the gallery-like spaces of the River City mall—in an exhaust-blackened shophouse on Bangkok’s oldest road, a long, narrow thoroughfare lined with low buildings, known to most expats as “New Road.” The junky antiques shop was located opposite Bangkok’s imposing main post office, and after mailing off a parcel one day, I spied its cluttered display window from across the street. I almost put off having a look—the road is difficult to cross on that block because a lack of traffic lights lets vehicles get up to speed—but a gap in the flow suddenly opened up, allowing me to sprint across.

Seen through the glass door, the inside of the shop looked deserted, but I tried the knob and it opened to the sound of jangly brass bells. The proprietor—a smiling Chinese gentleman whom I later learned was in his eighties—came in from a back room. He welcomed me with rather good English, but I switched into Thai as I began a spiel that would lead to a description of what I was after. This narrative was well rehearsed and allowed me to keep the conversation going toward my goal in a way that sounded natural and unhurried. It also kept the antiques merchant from wasting both my time and his by giving him too much freedom to offer me items that I had no interest in buying.

I began by asking if he had an example of the most ubiquitous piece of opium paraphernalia in existence: the porcelain pillow. Unlike a pillow for sleeping, the porcelain opium pillow was a raised platform for the head, enabling a smoker to comfortably lie on one side and allowing for an unobstructed view of the pipe bowl as it was held above the opium lamp. Every antiques shop in Bangkok seemed to have one or two of these on hand. The old gentleman indeed had one, but its green-hued glaze was badly chipped. After pretending to give the pillow an appraising look, I asked about other opium antiques. He went into the back room and returned with an old soup dish containing a selection of pipe bowls in one hand and a porcelain Chinese teapot in the other. The antiques merchant invited me to drink a cup of tea, letting me sit and examine the pipe bowls at my leisure.

During our conversation it came out that he was originally from Talat Noi, the neighborhood in Chinatown where I was living. Without any prompting he then told me about how he had visited the Chinatown opium dens as a child while accompanying his uncle, who was an enthusiastic smoker. The old merchant mimed smoking a pipe, and his gestures—he cocked his head to one side as though reclining—left little doubt he had witnessed the ritual firsthand.

I asked him where the dens used to be located and he smiled and said he didn’t know the present-day names for the warren of alleys that once made up the old opium quarter. Speaking in Thai, he attempted to give me directions: “The opium dens were located off Prosperous City Road, this road in front of my shop, the one you Westerners call New Road. Follow it across the bridge over the canal and then turn left down Lane 22. Then walk about a hundred meters and turn left into the first alley. Back then, Lane 22 was known as ‘Dog Shit Lane’ and the principal alley with many opium dens was called ‘Raw Ghost Alley.’ Go in there and ask the old folks; they’ll point to where the dens used to be.”

I bought a bowl from the proprietor, although it was rather common and plain, as a way to thank him for what I felt was a fascinating bit of local color. I wondered why I’d never before heard those vulgar old street names, but it was typically Thai to withhold such history on the assumption that a shady past would reflect badly on the present. On the walk back to my apartment I stopped at a hole-in-the-wall eatery that specialized in stewed duck and ordered my usual lunch of duck over rice.

As I was waiting for my order, I started a conversation with “Old Uncle,” the patriarch of the family-run restaurant, who was always puttering around collecting empty glasses and wiping food scraps from the stainless tabletops. I showed him the pipe bowl that I’d just bought and asked him to guess what it was. He knew. I then asked the old man if he had ever heard of “Raw Ghost Alley.” He laughed upon hearing the name. “One way into that alley is right there,” he said, pointing to a narrow walkway that passed right through a motorcycle repair shop next to the eatery.

“Do you mean there were once opium dens around here?” I asked.

“You’re sitting in an old opium den!” he said and laughed again, waving his arms around to indicate the very restaurant where I had lunch practically every day.

The news that I was living in Bangkok’s old opium quarter didn’t surprise me. At that point I was ready to believe that fate had drawn me to the neighborhood in the first place. Days later, I again brought up the subject with Old Uncle at lunchtime, and this time he elaborated on Raw Ghost Alley, pointing to another entrance some twenty yards away from the eatery and next to one of the neighborhood’s best preserved traditional Chinese homes. Despite having lived in the area for years, I had never explored these narrow alleys. I was curious but something always held me back. Just a peek down the alleys—there were toddlers playing among slumbering dogs and oldsters lounging in the shade—had been enough to convince me that I would be intruding had I strolled on in. I decided instead to let the sleeping dogs of Raw Ghost Alley lie, leaving it all unexplored for the time being.

Many months later, during the two-week opium smokefest that my forty-fifth birthday developed into, Raw Ghost Alley came back into my thoughts. The name was intriguing. Anyone who has lived in Southeast Asia for a longish spell will have noticed that ghosts are widely believed in throughout the region. While living in the Philippines, I often heard about people who had been visited by spirits—although I never met anybody who admitted to having actually seen one themselves. Later, when I began doing guidebook work, I frequently came across ghost stories—most often associated with hotels that were supposedly haunted—in Laos, Burma, Cambodia, and Thailand. In fact, some Thais seemed to be so terrified of the supernatural that it was difficult to get them to talk openly about ghosts; my inquiries about hauntings often produced bulging eyes and silence.

However, the ghosts referred to in the alley’s informal name weren’t the disembodied spirits of deceased opium smokers. In Thai, phi dip directly translates into English as “raw ghost,” but the meaning is actually more akin to the term “the living dead.” In other words, opium smokers in old Bangkok were thought of as zombies—people dead to the world yet still walking around among the living. Interestingly, “ghost” was also an American underworld term for opium smoker. But I didn’t think the imagery these words evoked was meant to paint opium habitués as slack-jawed ghouls. Instead, I felt the meaning probably conveyed the idea that opium smokers were withdrawn and no longer took an interest in society.

Rudyard Kipling’s short story “The Gate of the Hundred Sorrows” opens with what the author claimed was an old opium-smoker’s proverb: “If I can attain heaven for a pice, why should you be envious?” (“Pice” is the old Anglo-Indian spelling for “paisa,” a near valueless copper coin, one hundred of which made up a rupee.)

As I spent my birthday blissfully preparing one pipe after another, I could very much relate to the sentiment raised by Kipling’s proverb. Good quality chandu was no longer available for pennies, but why should anyone object if opium made the lives of those who chose to partake of it so delicious?

Why was opium illegal? From my vantage point next to the layout tray, the historic anti-opium crusades did look like petty envy—resentment soured by large doses of ignorance. Surely the banishment of opium was just another example of Victorian efforts to truss up society in a rigid corset of morality; the same kind of righteous zealotry that begat the temperance movements that led to the Volstead Act and a decade of Prohibition; the same hysteria that caused most countries in Europe to ban absinthe after a mass murder was wrongly attributed to the drink in 1905.

Starting in the last week of July 2007, I again forced myself to fast, this time abstaining from opium for an entire month—longer than I had gone without the drug since I began smoking with Roxanna. My birthday celebration, with its round-the-clock rolling, was exquisite, but during that two weeks of indulgence I’d done no work. It was time to catch up on some assignments. I found the weeklong detox period uncomfortable but manageable—reinforcing my belief that the torment of opium withdrawal had been grossly overstated. While working at my laptop, I noted that my mind often wandered to the mat, but I had no problem keeping to my fast, despite seeing the bottle of chandu rolling around on the egg shelf of my refrigerator every time I opened it.

In mid-August I was visited by an old friend whom I’d first met years before when she was posted at the U.S. embassy in Bangkok. Lisa Bailey was a Southerner who managed to shatter all the Southern stereotypes. She was also the first of what would become many American embassy friends whose transcendent coolness debunked my preconceived notions about whom the State Department sends abroad. I best remembered Lisa for an informal Bangkok nightclub she introduced me to. In a city known for its nightlife, this place was unique. Lisa and her friends had dubbed it “the Japanese speakeasy” because it apparently had no liquor license and was run as a hobby by a Japanese fashion designer who rented the building—a century-old mansion on a quiet back lane. There was a tiny, handwritten sign on the gate out front, but other than that, there was no indication the house was anything but a private residence. Here was a nightclub minus the loud music, flashing lights, and gyrating pole dancers. Instead there was a genteel atmosphere behind high hedges where one could throw house parties—imagine a scene from The Great Gatsby if West Egg had been in tropical Asia. There my embassy friends drank vodka tonics and bemoaned having to work in offices overseen by the sneering visage of Dick Cheney.

Lisa’s August 2007 visit to Bangkok immediately followed her having been posted in Afghanistan. We met at the tiny riverside café up against the Sheraton Hotel, which had become my usual place to meet people—this was where Helmut P. had begged me to stop collecting a few years before. Lisa was very excited about my recently published book and had bought a copy. We talked about what I had been doing to promote it, and I told her about the website that I had paid to have constructed, OpiumMuseum.com, on which images of my collection were displayed together with historical photographs of opium smokers in China, Southeast Asia, and America.

“Have you had a book launch party yet?” she asked.

“Who would pay for it?” I asked. “My publisher?”

“Why not?”

“I have absolutely no complaints about my publisher, but Silkworm Books is a small operation. I don’t think anybody gets a book launch party.”

“Well, why don’t you let me arrange one for you?” Lisa asked with an eager look in her eyes that told me she was serious.

It sounded like fun, but my first reaction was to decline. Lisa pushed the idea in a playful tone, but then let it drop after making me promise to let her know if I changed my mind. She had only a few more days left in Bangkok and said she was going to have a small get-together with friends to see her off. “We could make it into a goodbye party for me and a book launch party for you.”

I said I would give it some thought and we parted with a hug. On the walk back to my apartment I remembered how much I’d enjoyed the opening night of the exhibition in Rotterdam—which was unusual for me because getting a lot of attention was always something that made me uncomfortable. And then I remembered exactly why I had enjoyed both opening night and the demonstration at the tea house in Paris a few days later: Beforehand I had been smoking Armand Hoorde’s opium. I pictured the sweet little bottle of chandu in my refrigerator and felt a wave of excitement just like a kid feels during the last days of school before summer vacation. I decided then and there that I would break my fast for a worthy cause: my book launch party.

A few days later I was in a taxi arriving at a modern high-rise—the residence of the American embassy’s cultural attaché, who through Lisa had offered to host my party. Alone in the elevator, I straightened my collar before a wide mirror that covered the back of the compartment. My pupils were pinpoints, but I could detect no other clue that might give away the fact that I had broken my monthlong fast by smoking fifteen pipes prior to leaving my apartment. I had purposely arrived at the party early to get accustomed to the surroundings and help with setting up, but the host had already seen to all the arrangements: There was a table in the dining room, every inch of which was covered with platters of Thai food. Two stacks of copies of my book were arranged on a coffee table in the living room.

Lisa was already there. She was booked on a flight back to the States later that night so we took advantage of the quiet and talked over things before the guests began arriving. She said that quite a few people from the embassy would be there, although except for the host, I knew none of them because all of my embassy friends had rotated to new postings outside of Thailand. It didn’t matter. Atypically for me, I was looking forward to being in a room full of new faces.

I’ve known U.S. embassy people to be punctual, and these were no exception. By 7:30 P.M. the apartment was crowded with guests and I was kept busy being introduced and signing copies of my book. At one point there were sharp, ringing taps on a wineglass and I was asked to say a few words. Speaking in front of crowds has always been one of my least favorite tasks, but I was aided by the confidence-bolstering properties of opium—which seemed to turn my leaden tongue to silver.

The rest of the evening was spent chatting and answering questions. People approached me one at a time or in groups of twos and threes. Many of them had been in Southeast Asia for some time—not exactly old hands but savvy enough to know the score. After complimenting me on my book, they all seemed to ask the same question: Was it possible to smoke opium in Thailand?

Recreational drug users are well known for wanting to “turn on” others to an activity they find highly enjoyable. But recreational drug use, by its very definition, is something outside the realm of work or study—and for that reason I didn’t see myself as engaging in it. I was using opium for research, and, enjoyable as my experiences might have been, I knew there was nothing to be gained by introducing others to the bliss that I had found within the glow of the opium lamp. In fact, there was much to lose by doing so.

I smiled patiently as one person after another worked through some introductory small talk before popping the question. Was it my imagination or did I detect a glimmer of hope in their eyes? I became convinced that many of them wanted me to answer with a wink and a whisper. Instead, with the pupils of my eyes as tiny as poppy seeds, I shook my head with feigned regret as I shut the door on their hopes. “I’m afraid nothing remains of that old world,” I said.
