RecruitingPhase 1Drug trialClinical Study to Evaluate the Effects of Oral Delta-9-tetrahydrocannabinol (Δ9-THC) With and Without Alcohol on Perception and Driving Performance in Healthy AdultsWith the increasing prevalence and use of cannabis products by the public, there exists a need to better understand the safety impact of cannabis use, particularly when it comes to subjective perceptions of drug effect and driving impairment. This study aims to evaluate the dose-dependent effects of oral Δ9-THC alone and in combination with alcohol (0.08% BAC \[Blood Alcohol Concentration\]) on driving performance and subjective feeling in healthy adults. The results of this study will address current knowledge gaps on the effects of oral Δ9-THC on driving impairment across a clinically relevant dose range.
