A study from The Journal of Neuroscience dated January 28, 2015 was recently released with results from research on brain morphology of daily adult and adolescent users of marijuana.
Here are a few quotes from the study…
“The United States has seen changing trends concerning the acceptance of marijuana. As of 2013, 20 states had either decriminalized marijuana or legalized medical use. Colorado, Washington, Oregon, and Alaska have now legalized its recreational use. Concurrently, the popular press has shown significant interest in scientific studies on the effects of marijuana use.”
“Recent research has suggested that marijuana use is associated with volumetric and shape differences in subcortical structures, including the nucleus accumbens and amygdala, in a dose-dependent fashion. Replication of such results in well controlled studies is essential to clarify the effects of marijuana. To that end, this retrospective study examined brain morphology in a sample of adult daily marijuana users (n_29) versus nonusers (n_29) and a sample of adolescent daily users (n_50) versus nonusers (n_50).”
“No statistically significant differences were found between daily users and nonusers on volume or shape in the regions of interest. Effect sizes suggest that the failure to find differences was not due to a lack of statistical power, but rather was due to the lack of.”
“In sum, the results indicate that, when carefully controlling for alcohol use, gender, age, and other variables, there is no association between marijuana use and standard volumetric or shape measurements of subcortical structures.”
There is so much more in depth scientific data and information in this study that can be reviewed. If you are interested take a look.
