A Laboratory Model of Increasing THC Potency on Cigarette Smoking

The objective of the proposed research is to investigate how smoking increasing potency of THC (i.e., the psychoactive ingredient in marijuana) changes tobacco cigarette smoking behavior, urges, subjective effects, and abuse liability. This study will be a within-subjects, placebo-controlled study in our clinical laboratory of the effect of active vs. placebo marijuana on cigarette puff topography, exhaled carbon monoxide, urge, subjective effects, and abuse liability among 7 adults who smoke both marijuana and tobacco cigarettes.
