Households with adolescents face potential long-term economic consequences including reduced educational attainment, lower future earnings potential, and increased mental health treatment costs. Parents may increase spending on mental health services and educational support.
Likely to strengthen cannabis regulation for minors, increase age-restriction enforcement, and potentially trigger public health campaigns. May influence school policies and mental health funding. Could pressure cannabis industry toward stricter marketing controls and potency labeling. May drive demand for youth mental health services and educational interventions.
