Many patients desire the benefits of medical marijuana, but they hesitate to use it due to the negative stereotypes and stigmas that surround the plant. In the past, marijuana received a bad reputation, and was blamed for producing negative side effects, leading to bad habits or addictions, or causing mental illnesses and health problems. One theory suggested marijuana led to the development of psychosis, but now, research published in the journal Current Psychiatry Reports suggests it is unlikely that the use of marijuana contributes to the development of psychosis disorder.
The researchers from the University of Wyoming and Columbia University in New York analyzed recent studies surrounding the use of cannabis and psychotic behaviors, and reported cannabis use does not cause psychosis. Instead, the researchers found that subjects who are particularly susceptible to the disorder are more likely to engage in the early-onset of the use of cannabis. The researchers reported, " Evidence reviewed here suggests that cannabis does not in itself cause a psychosis disorder... Rather, the evidence leads us to conclude that both early use and heavy use of cannabis are more likely in individuals with a vulnerability to psychosis."
