During the second session, after again providing Breathalyzer and urine samples, participants completed the MWC, MCQ, POMS, and the Biphasic Alcohol Effects Scale (BAES). Electrodes were placed on the participant’s chest and lower back to monitor HR using the BIOPAC 100 system (BIOPAC Systems, Goleta, California, USA), and a baseline HR was recorded. Then, based on their preference, participants were exposed to either a used marijuana bong or pipe while sitting alone at a desk. Via audio tape, they were instructed to focus on the cue, smell it, and imagine what it would be like to smoke marijuana from it. The exposure lasted 2.5 m, after which participants completed the MCQ, POMS, and BAES.
