Study Summary
This primary aim of this study is to assess the effects of passive (second-hand) inhalation of cannabis smoke on toxicological analysis of "native" oral fluid (saliva), urine and blood specimens. The results of this study will help inform the validity of oral fluid as a biomarker of cannabis exposure and to determine whether, and for how long, passive inhalation of cannabis smoke could result in a positive toxicology result.
Primary Outcome
After exposure to cannabis, we will conduct a pharmacokinetic analysis of THC in blood collected.
