Note. CAN = Cannabis; ALC = alcohol; MON = money; AUC = area under the curve from purchase task data; k = delay discounting rate from 5-trial adjusting delay discounting task; Alcohol Heavy = past month heavy alcohol use days (5 or more [males] or 4 or more [females] drinks in a single day): CD Count = number of cannabis use dependence symptoms endorsed; Month Use = percentage past month cannabis use days. n = 64 cannabis users, sample sizes included in the table vary for each measure due to self-reported use or rates of systematic data. Bold = significant at p < .05
