Across Canada, the legal age for buying cannabis varies. This variation allowed researchers to study how these age limits affect hospital visits related to cannabis use among young people. They looked at data from 2015 to 2022, focusing on individuals aged 15 to 44.

    The study found that before cannabis was legalized, hospitalizations due to cannabis use were rising by 2% every three months for both younger and older individuals. After legalization, something interesting happened. For those below the legal age, hospitalizations started to decrease by 2% every three months. However, for those above the legal age, the rate of hospitalizations remained the same.

    Three and a half years after legalization, the number of hospitalizations for those below the legal age dropped by 34% compared to those above the legal age. This suggests that setting a minimum legal age for cannabis purchases might help reduce cannabis-related hospitalizations among young people.

    It's important to note that the study only shows a correlation, not a direct cause-and-effect relationship. Other factors could also influence these trends. For instance, education campaigns, changes in social attitudes, or even the quality of cannabis available might play a role.

    The findings raise questions about the broader impact of cannabis legalization. While it might reduce hospitalizations among youth, it could potentially increase them among adults. This highlights the need for ongoing research and careful policy-making. Policymakers need to consider how to balance the benefits and risks of cannabis legalization, especially for different age groups.

    The study also underscores the importance of setting appropriate legal ages for cannabis use. It shows that these age limits can have a real impact on public health outcomes. However, more research is needed to fully understand how these laws work in practice and how they can be improved.
