Science: Marijuana Users Ain't 'Stupid Stoners' The consumption of cannabis, even long-term, poses few adverse effects on cognitive performance, according to clinical trial data to be published in the scientific journal Addiction.
Investigators at the University of Melbourne and the Australian National University, Center for Mental Health Research assessed the impact of cannabis use on various measures of memory and intelligence in over 2,000 self-identified marijuana consumers and non-users over an eight-year period. Among cannabis consumers, subjects were grouped into the following categories: ‘heavy’ (once a week or more) users, ‘light’ users, ‘former heavy’ users, ‘former light’ users, and ‘always former’ — a category that consisted of respondents who had ceased using marijuana prior to their entry into the study. Separate studies have previously reported that long-term marijuana use is not associated with residual deficits in neurocognitive function.
