Healio (9/30, Gawel) reports a study found that “cannabis amplifies the effects of childhood trauma as a key driver of paranoia, indicating opportunities for trauma-informed clinical approaches and cannabis harm reduction strategies.” The study cohort “included 2,482 individuals (52%) who reported some form of trauma, including abuse (24.6%), neglect (19.1%), household discord (30.3%) and bullying (20.6%), based on a modified version of the Childhood Trauma Screen questionnaire adapted for this study. Results from the Green Paranoid Thoughts Scale yielded mean scores of 54.96 for those exposed to trauma and 43.67 for those with no exposure.” Researchers observed “associations between heightened paranoia symptoms and physical and emotional abuse strong, adding that physical and emotional abuse were the strongest predictors of paranoia.” In addition, the researchers “said participants exposed to sexual abuse had the highest weekly standard THC unit consumption.” They noted that “positive associations between weekly standard THC unit exposure also included emotional and physical abuse.” The study was published in Psychological Medicine.
