Official title
Dose Ranging Clinical Study to Evaluate the Effects of Oral Delta-9-tetrahydrocannabinol (Δ9-THC) With and Without Alcohol on Perception and Driving Performance in Healthy Adults
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
With 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.
