Summary
This study looked at how combining alcohol with high-THC cannabis concentrates affects people. 146 heavy drinkers who also use cannabis regularly took part. They drank alcohol and used their own cannabis product in a mobile lab, then had their blood drawn, breath tested, and completed surveys and cognitive tasks. The goal was to see if the order of use (alcohol first or cannabis first) and the THC level change intoxication, heart rate, and impairment.
