However, potential problems include harms from prenatal exposure unintentional childhood exposure; decline in educational or occupational functioning after early adolescent use, adulthood, impaired driving vehicle crashes; disorders (CUD), withdrawal, psychiatric comorbidity. Evidence suggests national increases potency, adults, increased CUD, cannabis-related emergency room visits, fatal crashes. Twenty-nine states have medical marijuana laws (MMLs) these, 8 recreational (RMLs). Many studies indicate that MMLs their specific provisions did not increase use. more limited literature led to exposures, adult CUD. Ecological-level suggest substitution for opioids, also possibly medications. Much remains be determined about trends role RMLs these trends.

Abstract Aims To conduct a systematic review and meta‐analysis of studies in order to estimate the effect US medical marijuana laws (MMLs) on past‐month use prevalence among adolescents. Methods A total 2999 papers from 17 literature sources were screened systematically. Eleven studies, developed four ongoing large national surveys, meta‐analyzed. Estimates MML effects any included obtained comparisons pre–post changes states non‐MML over comparable time‐periods. These estimates standardized entered into model with fixed‐effects for each study. Heterogeneity study by data survey was tested an omnibus F ‐test. additional outcomes, provisions (e.g. dispensaries) demographic subgroups abstracted summarized. Key methodological modeling characteristics also described. Preferred Reporting Items Systematic Reviews Meta‐Analyses (PRISMA) guidelines followed. Results None 11 found significant compared contemporaneous The yielded non‐significant pooled (standardized mean difference) −0.003 (95% confidence interval = −0.012, +0.007). Four pre‐MML differences all higher rates passage. Additional tests specific provisions, outcomes generally results, although limited heterogeneity may warrant further Conclusions Synthesis current evidence does not support hypothesis that until 2014 have led increases adolescent prevalence. Limited exists MMLs other patterns use, within particular population provisions.
