Note. AUC = area under the demand curve from purchase task data; k = discounting rate from 5-trial adjusting delay discounting task; % Month Use Days = percentage past month cannabis use days; # CD Symptoms = number of cannabis use dependence symptoms endorsed. n = 46 cannabis users. Bold = significant at p < .05
