60 Peer-Reviewed Studies on Medical Marijuana
Our list includes only peer-reviewed studies from 1990 to present that have been done using the marijuana plant or extracts derived from the plant, such as Sativex and Epidiolex. Studies involving synthetic reproductions of isolated compounds from the marijuana plant – e.g. products such as Marinol, Nabilone, Cannabinor, and others – were not included. Double-blind studies (in which neither the subjects nor the researchers know which patients are receiving the placebo or actual treatment) have been noted as such.
The studies are categorized as Pro, Con, or Not Clearly Pro or Con in relation to the specific purpose being investigated in the study. For example, a study showing a benefit of using marijuana to treat Multiple Sclerosis would be categorized as Pro. If the results were mixed, the study would be listed as Not Clearly Pro or Con. A study concluding that marijuana is not useful for treating the specific condition would be labeled Con.
We tried to find all the peer-reviewed studies related to testing the utility of marijuana in treating various health conditions since 1990, however we likely missed some. Despite our good faith efforts, please recognize that this list is neither exhaustive nor comprehensive.
