As much as the contents of the report, its irony -- as if the 1950s House Un-American Activities Committee had paid for a report finding that communists were good guys after all -- attracted a barrage of media attention. Gen. Barry McCaffrey, director of the Office of National Drug Control Policy, was forced to put on a brave face. McCaffrey, who since taking office in 1996 has called medical marijuana a "cruel hoax" and "Cheech and Chong" medicine, commissioned the report, which eventually cost $896,ooo, in January 1997, just months after California and Arizona became the first two states to endorse the use of marijuana for medicinal purposes. The study, "Marijuana and Medicine: Assessing the Science Base," was conducted by the National Academy of Sciences' Institute of Medicine, which in August 1997 assembled an eleven-person panel to conduct an eighteen-month investigation of marijuana's benefits and risks through a series of public hearings and exhaustive study of current research. What drew the most attention after the release of the report was its finding that some of the sixty-six "cannabinoid" substances found in smoked marijuana have "potential therapeutic value ... moderately well-suited for certain conditions, such as chemotherapy-induced nausea and vomiting and AIDS wasting." Less noticed, however, was the report's point-by-point dismantling of many of the key anti-marijuana arguments made by drug warriors. In understated, scientific language, the institute questioned the widely cited "gateway" theory, which holds that marijuana leads users on to harder drugs like heroin and cocaine; cast doubt on marijuana's addictive properties; rejected the notion that use of medical marijuana will stimulate wider recreational use of the drug; and knocked down the idea that marijuana is dangerous to its users. Not surprisingly, marijuana advocates cheered the report's conclusion and promised that behind these findings they would expand the campaign to win statewide ballot initiatives in support of medical marijuana. McCaffrey, on the other hand, was left with nothing to do but spin, citing the report's conclusion that smoking marijuana is a risky and uncertain method for delivering the drug's active ingredient, to the body. "The study concludes that there is little future in smoked marijuana as a medically approved medication," said McCaffrey in a statement faxed from his office. This point is essentially well taken. The report indeed notes that research into the potential uses of marijuana ought to emphasize pills, inhalers and other "non-smoked, rapid-onset cannabinoid delivery systems." But it also says that for certain patients, short-term use of smoked marijuana might be helpful. Until other delivery systems are developed, the report says, “there is no clear alternative for people suffering from chronic conditions that might be relieved by smoking marijuana, such as pain or AIDS wasting." It also points out that the very act of smoking marijuana raises serious concerns about respiratory diseases and cancer, similar to or even more intense than those associated with tobacco smoke. But if the danger of marijuana rests chiefly in the fact that marijuana smoke can cause lung and respiratory disease, that hardly justifies including marijuana in the War on Drugs. "By that measure, it would be logical to jail cigarette smokers,” says Bill Zimmerman, executive director of Americans for Medical Rights, the organization leading the effort to place medical-marijuana initiatives on statewide ballots. THE INSTITUTE OF MEDICINE'S task force scoured the literature for research on marijuana. Its researchers setup a Web site for public comment and solicited input from 130 organizations, and they also visited four cannabis-buyers' clubs in California and two HIV-AIDS clinics. In public hearings during the winter of 1997-98 in California, Louisiana and Washington, D.C., the report's authors and its advisory panel of scientists not only heard testimony from dozens of experts but also listened to a wide range of patients who use marijuana to treat AIDS, cancer, multiple sclerosis, glaucoma and other ailments. While noting that exact data are not available, the report says that based on its informal surveys, medical-marijuana users are over-whelmingly male, usually in their forties and typically suffering from AIDS. Cancer patients and victims of chronic pain, including back pain, are the next most common users of medical marijuana. Though patients' stories are often disparaged as anecdotal and unscientific, one of the study's two principal investigators, Dr. John A. Benson Jr., dean and professor emeritus at Oregon Health Sciences University School of Medicine in Portland, says, “in medicine, you start with anecdotes. The idea was to get a feel for, one, whether it is harmless, and two, whether it helped them. So we're educating ourselves and learning the scope of the illnesses." Many of the patients who appeared before the panel were located and organized by the Marijuana Policy Project, a marijuana-law-reform group based in Washington, D.C. According to Chuck Thomas, a co-founder of the MPP, the testimony from marijuana-using patients was crucial. "It humanized the issue," he says. "It took it out of the realm of just scientific data to show the human dimension." A case study cited in the report is that of "G.S.," who used marijuana to treat AIDS wasting syndrome. "After years of final-stage AIDS, I had wasted to 130 pounds," G.S. testified. "The purple Kaposi's sarcoma lesions were spreading. The dark circles under my eyes told of sleepless nights and half-waking days." But smoking marijuana, said G.S., "calmed my stomach against handfuls of pills [and] made me hungry again so that I could eat without a tube." Pot, he said, also eased his pain and "calmed my soul," leading him to accept the fact that he was likely facing death: "I lived to gain fifty pounds, regain my vigor and celebrate my thirty-fifth birthday." Says Benson, clearly moved, "The patients were enormously, enormously grateful to us. The National Institutes of Health didn't let them in the door, and, well, we seemed official. They just wanted someone to listen." DRUG WARRIORS ARE WORRIED THAT the report grants new legitimacy to medical marijuana, but they may have an even bigger problem on their hands, because the report also undercuts one of their most precious assumptions: the gateway theory. The warriors have argued for years that there is scientific and medical proof that among many users, pot acts as a steppingstone to more potent, more addictive and more dangerous substances. A leading advocate of that point of view is Dr. Herbert Kleber. Kleber works for the National Center on Addiction and Substance Abuse (headed by former Secretary of Health, Education and Welfare Joseph A. Califano Jr.) at Columbia University. He was selected as one of thirteen pre-publication reviewers of the report, but he says that his criticisms of it were ignored. He had urged its authors to give more weight to recent research showing that marijuana helps to release a chemical in the brain, called dopamine, the same chemical whose activation is triggered by harder drugs like heroin. By activating a sort of "reward system' within the brain, Kleber's argument goes, marijuana conditions the brain’s pleasure centers to certain kinds of stimulation and sends the user on a quest to deliver ever-greater kicks - from more powerful drugs - to those pleasure centers. "They didn't pick it up," says Kleber of the report's authors. He adds that the evidence of marijuana's effect on dopamine could be the “smoking gun" that could help prove the gateway theory. The Institute of Medicine report, however, explicitly dismisses this idea, noting that "brain reward systems are not strictly 'drug reinforcement centers.' Rather, their biological role is to respond to a range of positive stimuli, including sweet foods and sexual attraction." In other words, if marijuana is a gateway to cocaine, so are chocolate and sex. If pot is a gate-way to use of narcotics, the report continues, it may only be because of the drug's social and legal stigma. That is, users have to break the law to obtain marijuana, often interacting with dealers of other drugs. "There is no evidence that marijuana serves as a steppingstone on the basis of its particular drug effect," says the report. “Instead, it is the legal status of marijuana that makes it a gateway drug." Other points in the report: Marijuana, if addictive, is only mildly so, and few users develop a dependence on the drug. "They appear to be less likely to do so than users of other drugs (including alcohol and nicotine)," it says, "and marijuana dependence appears to be less severe than it is for other drugs." It adds, "A distinctive marijuana withdrawal syndrome has been identified, but it is mild and short-lived." It notes that in 1996 almost 69 million Americans over age twelve had tried marijuana, but only five percent of the population were current users. Contradicting those who say that approving marijuana for medical use or decriminalizing it would increase its use for recreational purposes, there port says, "At present the data on drug-use progression neither support nor refute the suggestion that medical availability would increase drug abuse." Also, it notes, "there is not strong evidence that decrirminalization [of marijuana] causes a significant increase in marijuana use." While noting that "marijuana is not a completely benign substance," the report says, "Except for the harms associated with smoking, the adverse effects of marijuana use are within the range [of effects] tolerated for other medications." Yet, it warns, abuse of marijuana can lead to "diminished psycho motor performance" (i.e., don't smoke and drive) and possible short-term effects on the body's ability to resist bacteria, viruses or tumors. All of this doesn't help McCaffrey’s War on Drugs, which in 1997, the most recent year for which FBI figures are available, resulted in the arrest of 695,000 Americans on marijuana-related charges, eighty-seven percent of them for possession. Mike Gray, author of Drug Crazy and one of the most knowledgeable critics of U.S. drug policy, points out that marijuana is the linchpin of the federal government's $17 billion drug war (a total that, he says, expands to $50 billion when state and local efforts and collateral programs are counted). Without marijuana's 10 million regular users, the drug war involves just 3 million users of other drugs, hardly a significant enough problem to sustain the all-out effort now under way, says Gray. "How would they justify it? You can't, once you take marijuana out of the mix." But taking marijuana out of the drug-war mix is not about to happen any time soon. Though the report suggests a wide range of research studies that might lead to more-concrete conclusions about marijuana's usefulness as medicine, it's unclear whether the powers that be -namely, McCaffrey's ONDCP, the National Institute on Drug Abuse and Congress - will allow such research to go forward. Both McCaffrey and Rep. Bill McCollum, a Florida Republican who bitterly opposes efforts to approve medical marijuana on state ballots, say that they will support further research, as recommended by the Institute of Medicine's report. And Benson, the Oregon scientist, says, "We hope that it will go on. It was our intent to suggest specific research projects." But others wonder who will be willing to put up the money - perhaps tens or even hundreds of millions of dollars-to develop cannabinoid-based medicines. (Only one such drug, called Marinol, a synthetic version of THC, the active ingredient in marijuana, is available in pill form now.) Private research into marijuana's usefulness is hamstrung; scientists cannot obtain samples of the illegal substance for research purposes except through NIDA, which is reluctant to make it available. "The Number One obstacle to this treatment is politics," says Daniel Zingale, executive director of AIDS Action. In February, the group joined up with dozens of other AIDS activists to urge McCaffrey to change U.S. policy on medical marijuana, to no avail, and also battled McCaffrey unsuccessfully over needle-exchange programs that could help prevent AIDS transmission via shared syringes. "If it weren't for the politically charged nature of this debate, the science would be driving the policy," says Zingale. "But the politicians are lagging behind the public." Certainty, the public favors the idea of medical marijuana. Polls consistently show strong support for marijuana for medical purposes, usually in the range of sixty to eighty percent, says Chuck Thomas of the MPP. But at the same time, the polls register a conflict: While favoring medical marijuana, Americans also exhibit a strong and fervent opposition to the legalization of marijuana for nonmedical use. A poll taken for the. American Civil Liberties Union revealed that two-thirds of Americans oppose legalization, most of them adamantly, and fifty-seven percent agree that using marijuana to get high is morally wrong. Bill Zimmerman, who helped engineer the medical-marijuana ballot initiative in California in 1996, as well as successful votes last year in Alaska, Oregon, Washington and a first round in Nevada, says that medical marijuana will appear on ballots in more and more states - - unless the federal government radically revises its marijuana policy. Maine will vote on a medical-marijuana initiative this year; in 2000, votes will be taken in Colorado and Nevada. Popular or not, the idea of using marijuana for medical purposes is a non-starter in Congress. Last September, Bill McCollum, perhaps Congress' leading militant in the War on Drugs, organized passage of a House of Representatives resolution condemning efforts to approve marijuana for medical use. Hard-core conservatives like Georgia Republican Rep. Bob Barr - who called the Institute of Medicine report "a waste of taxpayer money and another step toward drug legalization" - - can be counted on to raise a furor over, say, research money to study medical marijuana use. Says Zingale, "I think that we have a long, long way to go before Congress understands this issue." - --- MAP posted-by: Richard Lake
