While a doubling of incident psychosis appears significant, analysis of the cohort (N=463,396) reveals that 99.14% of adolescent users do not develop the cited disorders. This alarmist framing exemplifies Base Rate Neglect, prioritizing a "Moral Panic" narrative over objective epidemiology.

Furthermore, the data identifies Socioeconomic Deprivation and Medicaid enrollment as more definitive predictors of psychiatric onset than cannabis exposure. By isolating high-potency THC as the primary "culprit," the authors execute a Social Selection Fallacy, ignoring the tripling of risk associated with poverty and familial instability. This secularized temperance rhetoric displaces blame from systemic failures onto individual behavior, suggesting an ideological bias toward state intervention rather than the mitigation of root-cause environmental stressors.
