Seven Legal Marijuana Patients • NIDA supplies marijuana to seven patients under FDA Compassionate Use Program. • Russo E, et al.

Journal of Cannabis Therapeutics Vol. 2 (1) (2002): 3 -57. (MAPS supported-in part by grandson of W. Erastus Upjohn)
Efficacy Conclusions • Cannabis smoking, even of a crude, lowgrade product, provides effective symptomatic relief of pain, muscle spasms, and intraocular pressure elevations in selected patients failing other modes of treatment. • Patients reduce use of other prescription medicines and improve quality of life.
Safety Conclusions • Side effect profile of NIDA cannabis in chronic usage suggests mild pulmonary risk. • No malignant deterioration observed, nor consistent or attributable neuropsychological or neurological deterioration. • No endocrine, hematological or immunological sequelae observed.
Medical Marijuana Research • At present, there is no research outside of the US in which smoked marijuana is being administered to patients in a clinical research study. • Research is proceeding with marijuana extracts such as sublingual lozenges and THC capsules (Marinol).
Dr. Abrams Marijuana/AIDS Research • Recently completed, this is the first FDAapproved study of the use of marijuana in any patient population in 15 years! • Study took 7 years to obtain approval, MAPS worked closely with Dr. Abrams and funded two of his NIH grant applications. • Funded by NIDA- $1 million.
Study Design • 21 -day in-patient study, HIV+ patients taking protease inhibitors • Twenty-one subjects were randomized for smoked marijuana, 25 for oral dronabinol, and 21 for the oral placebo. • Viral loads (HIV RNA levels), immune system, caloric intake, weight gain.
Dr. Abrams’ conclusions • Patients with HIV infection taking protease inhibitors do not experience short-term adverse virologic or immunological effects from using smoked marijuana or oral THC as compared to placebo. • Caloric intake and weight gain highest in marijuana group >oral THC > placebo. • Paper under review
Medical Marijuana Research • There is only one study in the US in which smoked marijuana is being administered to patients, in this case to AIDS patients. • Dr. Dennis Israelski, chief of infectious diseases and AIDS medicine at San Mateo County Hospital and Clinics. • Funded by San Mateo County.

Nicole Achs Freeling, Half Moon Bay Review, October 13, 2001
Lone Patient Quits Study • "The pot was stale and it was full of seeds. When marijuana seeds burn, they smell and taste really bad. " • “Apparently, the two joints a day that he was required to smoke through the study had aggravated a throat condition. The doctor issued an edict - no more smoking NIDA marijuana. ”
NIDA’s Product • “We know the level of THC is lower in this federal-provided marijuana [ than what patients purchase through buyer’s clubs] , but unfortunately we don't have any control over that. We have to use whatever we're given by the federal government for this study. " Jonathan Messinger, assistant to program director Dr. Dennis Israelski.
Back to Illicit Supplies • “Once his throat condition clears, Alden says he will go back to treating himself at the cannabis clubs. ” • "It works. I have no doubt about that, " he said.
NIDA’s Monopoly • NIDA has a monoply on the supply of marijuana that can be used in FDAapproved research. This is the only Schedule 1 drug for which NIDA has a monopoly, not MDMA, LSD, psilocybin. • NIDA, whose mission is to research the harms of marijuana, must approve all research into marijuana’s potential benefits.
