The medicinal uses of marijuana span a wide variety of diseases and disorders, but a recent study conducted by Colorado State University indicates that cannabis may not be as useful for treating depression and anxiety.
In December 8, researchers in the Department of Psychology at Colorado State University published a study regarding the relationship between marijuana use and depression and anxiety in study participants. Led by professor Lucy Troup, a cognitive neuroscientist at CSU, the study focused on the residual effects of marijuana over time on three groups of students — casual users, chronic users and non-users — and observed how individuals assessed their levels of depression and anxiety.
