Working with the Heavy Cannabis User

In our teaching clinical at the North American Institute of Medical Herbalism in Boulder, Colorado, we began to see an increasing number of heavy Cannabis users as patients after the legalization of Cannabis dispensaries in 2010. This course is based on a review of the cases and histories of more than 40 patients using between 4 and 10 doses of Cannabis per day, or using highly concentrated forms more than once a day. We began to recognize a consistent pattern of complaints and side effects in these patients which were consistent with side effects and withdrawal symptoms reported in the scientific literature and by such groups as Marijuana anonymous. About 1/3 of these patients were seeking assistance to cut down or quit Cannabis use after repeated attempts on their own to do so, and we got hands-on experience with different strategies.

Course Overview

Beginning in 2016, the NAIMH did a thorough scientific literature review of issues surrounding tolerance, dependence, side effects and withdrawal symptoms, and updated this review in 2021. In this course, we include example case reports, and also present more than 35 fully referenced scientific articles and literature on the topic, as well as specialized intake forms and educational materials for patients.

We are vigorous advocates for the complete legalization of Cannabis, but we feel that the safety insert on a package of medical marijuana should say more than “But its safer than alcohol.” Practitioners and patients should know what to expect and how to recognize the common effects, side effects, and withdrawal symptoms. This course can be helpful for the health professional working with heavy daily users of Cannabis, whether medical or recreational, or if you are a heavy user yourself.
