Despite the obvious opportunity to generate data on the use of cannabis by these patients, and its possible sequelae, neither NIDA, other branches of the National Institutes of Health, nor the FDA has ever attempted to collect or analyze information from this cohort. The Missoula Chronic Cannabis Use Study provides a unique and important opportunity to amass and analyze the long-term effects of cannabis on patients who have used a known dosage of standardized, heat-sterilized quality-controlled supply of low-grade medical marijuana for 8-22 years. Six of the eight remaining legal patients have agreed to participate in this study. Two prefer to retain anonymity.
Each study patient will undergo the following tests:
The proposed study will be conducted at St. Patrick Hospital and the offices of Montana Neurobehavioral Specialists, Missoula, Montana. Institutional Review Board (IRB) approval for the study has been obtained. The study will be co-conducted by Ethan Russo, MD, and Mary Lynn Mathre, RN. The essence of the study is to evaluate the functional condition of these chronic cannabis patients. All physiological systems will be probed to some degree but concentration will be on pulmonary and neurological functions. Three subjects were fully evaluated from May 3 - May 6, 2001.
MAPS has pledged $10,000 to this study, as has a private donor, while the Zimmer Family Foundation has pledged $1050. The results of the study are to be distributed as widely as possible. Data will be presented at the International Cannabinoid Research Society meeting in Madrid, Spain, in June 2001, and at the Second National Clinical Conference on Cannabis Therapeutics to be held in Portland, Oregon, in the spring of 2002.
A full report of the results will be published in the Journal of Cannabis Therapeutics. Articles on the study will also be submitted to peer-reviewed journals of wide circulation.
This is designed as a one-time study. Replication is possible at a future time if the need or advisability of such replication is deemed appropriate, and if the patients agree to participate. When completed this study can serve as a baseline for future comparisons.
