The 'ban' for public health that wasn't? Views and impressions on cannabis retail promotion/advertising realities amidst legalization policy in Canada

Should cannabis self-cultivation be part of a public health‒oriented legalization policy framework?

Cannabis control policies are increasingly being liberalized, including the legalization of non-medical cannabis use and supply in multiple settings, for example in Canada, with main policy objectives focusing on improved public health. An important while contested matter has been the appropriate design of legal cannabis supply structures and sources. These, in most Americas-based legalization settings, have included provisions for (limited) 'home cultivation'. Recent data suggest that about 8% of active consumers engage in cannabis home cultivation for their own supply, while approximately 14% are exposed to it in/around their home. Home cultivation commonly exceeds legal limits and/or occurs where not allowed, and is disproportionately associated with high-frequency and/or other risk patterns of cannabis use. In addition, home cultivation may facilitate exposure or diversion of cannabis to minors, as well as pose possible environmental exposure risks especially when occurring indoors. Given its placement in private spaces, related regulations are largely shielded from enforcement. Home cultivation, therefore, bears substantive potential to circumvent or work counter to public health‒oriented legalization policy objectives. Recent assessments of health outcomes from cannabis legalization show mixed-including multiple adverse-results, implying the need for regulatory revisions towards protecting public health outcomes. Especially in settings where extensive (e.g. commercial) retail systems were established to provide regulated, legal cannabis products to consumers, it is questionable whether home cultivation overall serves primary public health‒oriented objectives; relevant data should be expanded and used to review related provisions.

Germany's cannabis act: a catalyst for European drug policy reform?

With the enforcement of the Cannabis Act on 1 April 2024, Germany has adopted one of the most liberal legal approaches to cannabis on the continent. The German model prioritises a non-profit approach and precludes legal market mechanisms. We believe these are the main drivers for increasing cannabis use and related health problems, based on observations following cannabis legalisation in Canada and many states in the U.S. Although legalising cannabis possession and cultivation may not immediately eliminate the illegal market, it is expected to serve public health goals. Despite the overall positive evaluation of the Cannabis Act in Germany, there are three potential areas of concern: the potential for misuse of the medical system, the normalization of cannabis use, and the influence of the cannabis industry. The German model may herald the beginning of a new generation of European cannabis policies, but concerted efforts will be required to ensure that these policy reforms serve rather than undermine public health goals.
