Don’t make a hash of it! A thematic review of the literature relating to outcomes of cannabis regulatory change

Globally cannabis regulations are rapidly changing. In recent years social and political pressure, not science, has driven this change. Experience from jurisdictions that have implemented regulatory change, although relatively new, should be used to inform future policy development for other jurisdictions, assisting in addressing the wicked problem that cannabis regulations present. This review aimed to elicit underlying themes from a broad range of literature exploring the effects of regulatory change relating to cannabis. To achieve this a meta-narrative theoretical approach using inductive constant comparative analysis was used to synthesize data until thematic saturation was reached. Following a systematic literature search, 92 papers were analyzed before thematic saturation was complete. Five super-ordinate themes emerged that observed the societal and health effects following legislative and regulatory change: Normalization; Economics; Gatekeeping; Community and Health. These themes, empirically derived through a formal qualitative approach, were considered regarding cultural contexts, providing an understanding of how cannabis regulation is changing the social landscape. Consideration of the themes during future research may provide a focus point for the discussion of legislation and policy, not only relating to cannabis, but also other broad-ranging areas such as social policy, welfare, education and health.
