(a) Alcohol effects on breath alcohol levels throughout the session. ‘Drink' shade corresponds to the timing and duration of alcohol/placebo ingestion, and ‘fMRI scan' corresponds to the timing and duration when brain activation was measured. (b) Alcohol effects on self-reported desire to smoke ratings. Alcohol elicited greater smoking urge (>placebo) at 45, 60, and 75 min after initiation of beverage consumption. ‘Drink' shade corresponds to the timing and duration of alcohol/placebo ingestion, and ‘fMRI scan' corresponds to the timing and duration when brain activation was measured. ^*p<0.05, two-tailed.
