Primary	Frequency of Cannabis Use as Reported on the Timeline Follow-Back (TLFB)	30-day TLFB self-report will be used to assess total number of days of cannabis use.	3-months post baseline
Primary	Frequency of Cannabis Use as Reported on the Timeline Follow-Back (TLFB)	30-day TLFB self-report will be used to assess total number of days of cannabis use.	6-months post baseline
Primary	Quantity of Cannabis Used as Reported on the Timeline Follow-Back (TLFB)	30-day Timeline Follow-Back (TLFB) self-report will be used to assess quantity (grams) of cannabis consumed.	3-months post baseline

Primary	Consequences of Cannabis Use as Measured by the Marijuana Adolescent Consequences Questionnaire Using Dichotomous Response Scale as Previously Described Throughout This Trial Registration.	Marijuana Adolescent Consequences Questionnaire will be used to assess past 3 month consequences of cannabis use. Consequences are measured by report of number of times incidents from the list of 26 items (e.g., quality of work suffered, had less energy, etc.) resulted from cannabis use. Responses will be dichotomized (0 = never, 1= greater than never) and summed for a total score reflecting total number of consequences.; Response scale: Never 1-2 times 3-5 times 6-10 times More than 10 times; Minimum score =0, maximum = 26. Higher score = more consequences.	3-months post-baseline

Higher score = more consequences.	6-months post-baseline
Secondary	Perceived Risk of Cannabis Use as Measured by 2 Modified Items From the Monitoring the Future Survey	Two items rating current opinion on a scale from "no risk" to "great risk" of their perceived risk harm from occasional cannabis use and regular use.; Items are--; How much do you think people risk harming themselves (physically or in other ways), if they: Use marijuana or marijuana products occasionally; Use marijuana or marijuana products regularly; Response options are: No risk; Slight risk; Moderate risk; Great risk; Answers from both items are added together. The total range of two items summed can be 2-8. Higher totals indicate higher perceived risk.	3-months post-baseline
