The Connecticut State Legislature has introduced House Bill 7258, aimed at addressing the growing concerns surrounding driving under the influence of cannabis and psilocybin. Proposed on April 23, 2025, the bill mandates a study by the Department of Emergency Services and Public Protection to explore the feasibility of establishing specific blood levels of tetrahydrocannabinol (THC) and psilocybin that would classify a driver as per se intoxicated, similar to existing laws for blood alcohol content.

The bill directs the department to analyze the driving under the influence frameworks of several states, including Colorado, Illinois, Montana, Nevada, Ohio, and Washington, which have already implemented various measures regarding cannabis and psilocybin use. The findings from this study are expected to be reported by February 1, 2026, along with recommendations for potential legislation on setting these blood level thresholds.

Key discussions surrounding the bill have focused on public safety and the implications of legalizing cannabis and psilocybin. Proponents argue that establishing clear legal limits is essential for ensuring road safety and providing law enforcement with the necessary tools to address impaired driving. However, there are concerns regarding the scientific validity of measuring impairment through blood levels, as the effects of cannabis and psilocybin can vary significantly among individuals.

The bill's introduction comes at a time when states are increasingly grappling with the implications of drug legalization and its impact on public health and safety. Experts suggest that the outcomes of this study could lead to significant changes in how Connecticut approaches drug-related driving offenses, potentially influencing future legislation and law enforcement practices.

As the bill progresses, it will likely spark further debate on the balance between personal freedoms and public safety, making it a noteworthy development in Connecticut's legislative landscape. The study's findings could pave the way for new regulations that may reshape the state's approach to driving under the influence of these substances.
