High Potency Cannabis Associated with Mental Health Issues in Adolescence
A study from the University of Bristol, the first of its kind to look at data from a general population sample, finds that those who use high-potency marijuana (10 percent or more THC) are four times more likely to report associated problems and twice as likely to report anxiety disorder, compared to those who use low-potency marijuana (less than 10 percent THC).

Understanding Opioid Use Disorder
Early initiation of marijuana (before 18 years) emerged as the dominant predictor. Decision trees revealed that early marijuana initiation especially increased the risk if individuals: (i) were between 18-34 years of age, or (ii) had incomes less than $49,000, or (iii) were of Hispanic and White heritage, or (iv) were on probation, or (v) lived in neighborhoods with easy access to drugs. Conclusions: Machine learning can accurately predict adults at risk for OUD, and identify interactions among the factors that pronounce this risk. Curbing early initiation of marijuana may be an effective prevention strategy against opioid addiction, especially in high risk groups.
