"Canada's Cannabis Five Times Stronger: Efficiency or Safety - Balancing the 'Potency' of Canadian Cannabis"

In Canada, over the past 20 years, the THC concentration in cannabis has increased approximately fivefold, ushering in an era of "high-THC" where much of the dried flower in the legal market contains over 20%. Research indicates a strong association between high THC and the risk of psychosis, particularly among young, male, and frequent users. The final report from the health department recommends "smart regulation," including defining high THC, adding warnings, clarifying standard doses, and using tax measures as disincentives. On social media, there are discussions about the rigor of causality, mentions of CBD's buffering effects, demand for "weaker weed," and realistic support for regulations like caps and labeling in the legal market. For consumers, key low-risk practices include "Start low, go slow" (using low concentrations in small amounts), avoiding alcohol combination, and preventing overconsumption of edibles. The industry is called to expand low-THC or THC:CBD balanced products, while policy demands comprehensive interventions such as labeling, standard dosing, taxation, and research support.
