Introduction

The global shift toward cannabis legalization has triggered intense debate regarding its long-term impact on public health. While proponents highlight economic benefits and criminal justice reform, concerns remain about increased accessibility, normalization, and potential rise in adolescent use, impaired driving, and cannabis use disorders [1-5]. As more jurisdictions move to legalize recreational cannabis, post-legislation data becomes crucial to assess its real-world consequences. This study analyzes post-legalization trends in cannabis use, health-related outcomes, and social behaviors across multiple regions, offering insights into the broader public health implications of this evolving drug policy [6-10] .

Discussion

Trend analysis across several regions with legalized cannabis showed a modest increase in adult use, particularly in those aged 26–35, while youth use either remained stable or slightly declined—possibly due to stricter regulation and reduced illicit market presence. However, emergency room visits related to cannabis intoxication and psychotic episodes rose, especially among first-time users and those using high-THC products. There was also an uptick in impaired driving incidents, suggesting a need for improved public education and roadside testing protocols. On the positive side, legalization contributed to reduced opioid-related deaths in some areas, potentially due to substitution effects. Cannabis-related arrests also significantly decreased, easing burdens on the legal system. The findings indicate that policy design—including age restrictions, advertising control, and taxation—plays a critical role in shaping outcomes. Public health campaigns must accompany legalization to educate communities on responsible use and potential risks.

Conclusion

Cannabis legalization carries both benefits and risks. While it may reduce criminal justice costs and offer therapeutic alternatives, it also poses challenges related to health care utilization and impaired behavior. Careful policy implementation, coupled with surveillance and health education, is essential to maximize public benefit and minimize harm in the post-legalization era.
