Study: Adolescent Marijuana Use Not Associated With Health Problems In Early Adulthood

Marijuana use by adolescents, including self-reported chronic use, is not associated with adverse health effects later in life, according to an assessment of longitudinal data published in the journal Psychology of Addictive Behaviors. Authors concluded, “Overall, data from this sample provide little to no evidence to suggest that patterns of marijuana use from adolescence to young adulthood … were negatively related to the indicators of physical or mental health studied.”

Study: THC Increases Brain Activity In Response To Positive Stimuli

The administration of THC modulates emotional processing in healthy volunteers, according to placebo-controlled crossover trial data published online by the journal European Neuropsychopharmacology. Researchers concluded: “These results indicate that THC administration reduces the negative bias in emotional processing. This adds human evidence to support the hypothesis that the endocannabinoid system is involved in modulation of emotional processing. Our findings also suggest a possible role for the endocannabinoid system in abnormal emotional processing, and may thus be relevant for psychiatric disorders such as major depression.”
