About Michael Castleman



KILLER WEED Plot Summary

Financial ruin threatens longtime stoner and historian-turned-journalist Ed Rosenberg. He and his wife, Julie, victims of newspapers’ decline, have just been fired from the San Francisco Foghorn.

Scrambling for work, Ed lands a gig researching the hippie Haight-Ashbury for a museum exhibit sponsored by a tech billionaire whose birth mother was a small-time marijuana dealer shot to death in Golden Gate Park in 1968, a killing never solved. Meanwhile, Julie is hired as media liaison for mayoral candidate Dave Kirsch, a former pot dealer and author of best-selling guides to growing weed. Then Kirsch is murdered in Golden Gate Park. His death costs Julie her job and returns the couple to the brink of financial disaster.

Ed’s research about the hippie Haight-Ashbury’s tie-dyed past vividly illuminates that era. The derivation of “psychedelic”? How the Grateful Dead and Jefferson Airplane got their names? All that and more in Killer Weed. Ed’s investigation also introduces him to a rogue’s gallery of characters—a hairdresser, florist, laundromat operator, and real estate mogul— who, he realizes, may have been involved in the ex-dealer’s murder. Then someone starts shooting at him.

The pages turn quickly and San Francisco—both then and now— comes alive. Killer Weed features remarkably true-to-life characters, and a compelling, nuanced portrait of a marriage under duress. Their careers upended, Ed and Julie feel anxious and stressed—and both use drugs to cope. He smokes more weed, which she doesn’t like, and she drinks more alcohol, which he can’t stand. Will the marriage survive?

While Killer Weed is a mystery, it’s more than a standard whodunit. It’s the only book that recounts the real forty-year history of marijuana dealing in America—importation from Mexico, then rendezvous with Colombian freighters on the high seas, followed by outdoor cultivation in national forests, to indoor growing under solar-powered lights. Castleman’s portrait of the business side of weed is so detailed and authoritative, you’ll wonder what this author has actually been doing the past four decades.

Killer Weed is a fast-paced, ingeniously plotted novel with characters so real you’ll want to turn on, tune in, and drop everything to reach the surprising, deeply satisfying conclusion.


Why Castleman Wrote KILLER WEED

Mur­der is cen­tral to each of Michael Castleman’s Ed Rosen­berg nov­els, but in addi­tion, each book also deals with San Fran­cisco history—everything from the events of 1906 to the bit­ter dock strike of 1934. In Killer Weed, the focus is the hip­pie era and the marijuana/cannabis indus­try, specif­i­cally, dope deal­ing from 1965 to the present day.

Castleman did not live in San Fran­cisco dur­ing the late 1960s. He was fin­ish­ing high school in New York. But he embraced hip­pie culture, and from 1968 to ’75, lived in Ann Arbor, Michi­gan, a col­lege town that had a strong hip­pie vibe, many deal­ers, and mar­i­juana activism that, in 1973, passed the nation’s first decrim­i­nal­iza­tion law—a $5 fine for posses­sion. Castleman arrived in San Fran­cisco in 1975, and lived in the Haight-Ashbury for sev­eral years, inhaling its cul­ture—in more ways than one. In addi­tion, he’s read exten­sively about that era, but none of the books described the 40-year sweep of the mar­i­juana busi­ness. He wanted to cor­rect that.

In addi­tion, Castleman is a strong sup­porter of cannabis legal­iza­tion. He’s a mem­ber of NORML, the Drug Pol­icy Alliance, and the Mar­i­juana Pol­icy Project. “It’s totally insane,” he says, “that alco­hol and tobacco are legal, yet annu­ally kill 85,000 and 450,000 Amer­i­cans respec­tively, while weed is ille­gal but kills few, if any. It’s ridicu­lous that enforce­ment of point­less pro­hi­bi­tion laws costs bil­lions of tax dol­lars, while legal­iza­tion would gen­er­ate bil­lions in tax rev­enue, save a for­tune in prison costs, and reduce the vio­lence asso­ci­ated with drug traf­fick­ing. Finally, with appro­pri­ate diag­no­sis and dose con­trol, cannabis is less likely to harm than heal.”

Character Names in KILLER WEED

Michael Castleman was named for a deceased relative, a Jewish custom. Castleman has adapted it to his novels, naming characters after people he’s known who have passed away. “My characters’ personalities are not inspired by their namesakes, but their physical descriptions are.”

Chief among Castleman’s memorials is his protagonist, Ed Rosenberg. “I met Eddie in seventh grade and we remained friends until he died—way before his time—of an undiagnosed heart defect in 1987 at age 37. I’m still in touch with his parents, now frail and living in Florida.”

Another old friend memorialized in the book is Carol Covington. In the book, she’s a former editor of the San Francisco Oracle, who becomes a teacher and directs a gospel choir. “I met Carol when we were twelve. She was one of the warmest people I’ve ever known. She died in 2010 at age 60.

Other memorial names include: Castleman’s father-in-law Gene Simons, and Ken Kelly, Sandra Selden, Pat Lucas, Wallace Turner, Joe Bogen (real name Ellenbogen), Dave Kirsch (Kirschberg).

“Naming character has always been difficult for me,” Castleman says. “Memorializing solves that problem while honoring the memories of people I’ve known.”

Persuading Dealers to Talk: How Michael Castleman Researched KILLER WEED

Michael Castleman has been a cannabis consumer since 1967 when a high-school friend first turned him on. During the past 45 years, he has read extensively about the business, but more importantly, over the years, he has coaxed many of his dealers to reveal how they’ve obtained their weed and run their businesses.

“It never ceased to amaze me how forthcoming most dealers are,” he says. “You’d think they’d keep quiet—and some won’t say a word—but most have been only too happy to discuss everything from their supply chains (minus names) to their stories for the taxman.”

Castleman has purchased cannabis from dealers who imported from Mexico, Panama, and Jamaica, who offloaded from Colombian freighters on the high seas, and who have grown it outdoors and more recently indoors. Currently, Castleman has a California medical marijuana card and buys from a store in San Francisco that’s vertically integrated. The owners grow it indoors at various locations around the Bay Area and sell mostly what they grow, obtaining the rest from other local growers.

Few of Castleman’s dealers have had front businesses through which they’ve laundered illegal income, but among those with fronts, businesses have included: a clothing store, consulting firm, auto repair shop, and rental real estate.

All the dealers in Killer Weed are fictional, but one, Paul Nightingale, is based on a friend Castleman met in the late 1970s. In the book, Nightingale starts with smuggling a few pounds at a time from Mexico and winds up offloading tons from Colombian freighters off the coast of Northern California until he’s arrested by the DEA. Nightingale has no front and spends a decade in federal prison for drug crimes and tax evasion.

The model for Nightingale started out driving a few pounds from Mexico to the Northeast. Eventually, he bought hundreds of pounds at a time from Colombian freighters off the coast of Maine. He laundered his drug money through a portfolio of real estate investments, but eventually got caught and spent several years in federal prison. In addition, under the RICO law—racketeer-influenced corrupt organizations—the IRS seized his buildings. After his release, he returned to real estate. Castleman lost touch and does not know if he returned to dealing.

“Any business is interesting,” Castleman says, “but illegal businesses are fascinating because the owners must be especially shrewd and creative.”
