Only individuals who are in good mental and physical health, with a BMI of 17-30 kg/m2, as verified by health questionnaires and the Structured Clinical Interview for DSM-IV (SCID), will participate in this study.

Additionally, subjects will fulfill one of two criteria: 1) not smoke or use other tobacco products or 2) smoke tobacco cigarettes or use other nicotine delivery systems (e.g., hookah, cigars, chewing tobacco) fewer than 5 times per day (on average) for the past year. Current use of MJ and tobacco will be verified by detectable urine Tetrahydrocannabinol (THC) and nicotine metabolites. All subjects will be required to provide four pre-quit baseline urine samples. The mean creatinine-normalized THC concentration across these samples must be of 175 ng/ml or greater based. -~Exclusion Criteria:~Criteria include meeting DSM-IV criteria for current abuse or dependence on a substance other than MJ, nicotine, or caffeine, using psychoactive substances (other than MJ, alcohol, nicotine, \& caffeine) 6+ times/month, testing positive for stimulants, antidepressants, anxiolytics, and/or opiates (10-panel urine drug test), testing above a salivary cotinine concentration of 150 ng/ml during the initial screening, using creatinine or creatinine-containing supplements, testing positive for adulteration of urine samples, consuming more than 6 alcoholic drinks per day continuously for a month, mental disorders including bipolar disorder, schizophrenia, psychotic symptoms, currently, recently, or ever chronically at significant suicidal risk or experiencing violent thoughts or current major depression.
