NEW STUDY ON NEGATIVE LONG-TERM EFFECTS OF HEAVY MARIJUANA USE ON BRAIN FUNCTION AND BEHAVIOR

A study published in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging looked at the effects of heavy marijuana use on brain function and behavior. The accompanying press release summarizes, "Young people with cannabis dependence have altered brain function that may be the source of emotional disturbances and increased psychosis risk that are associated with cannabis abuse. The alterations were most pronounced in people who started using cannabis at a young age [emphasis added]. The findings reveal potential negative long-term effects of heavy cannabis use on brain function and behavior, which remain largely unknown despite the drug’s wide use and efforts to legalize the substance."
