Primary Outcome Measures :
  1. Change in frequency of cannabis use as reported on the Timeline Follow-Back (TLFB) [ Time Frame: 3 and 6 months post-baseline ]
    30-day TLFB self-report will be used to assess total number of days of cannabis use.

  2. Change in quantity of cannabis used as reported on the Timeline Follow-Back (TLFB) [ Time Frame: 3 and 6 month post-baseline ]
    30-day Timeline Follow-Back (TLFB) self-report will be used to assess quantity (grams) of cannabis consumed.

  3. Change in Consequences of Cannabis Use as measured by the Marijuana Adolescent Consequences Questionnaire [ Time Frame: 3 and 6 months post-baseline ]

    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



Secondary Outcome Measures :
  1. Change in perceived risk of cannabis use as measured by modified items from the Monitoring the Future survey [ Time Frame: 3 and 6 months post-baseline ]
    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.

  2. Change in peer approval/disapproval of cannabis use as measured by item modified from Monitoring the Future Survey [ Time Frame: 3 and 6 months post-baseline ]
    One item rating of current perception of whether their close friends would disapprove of their cannabis use (regardless of how much they use), rated as: 1 Not disapprove 2 Disapprove 3 Strongly disapprove

  3. Changes in cannabis impaired driving as measured by 5 items from the modified Young Adult Driving Questionnaire [ Time Frame: 3 and 6 months post-baseline ]

    Five items from the modified Young Adult Driving Questionnaire will be used to assess past 3 month driving under the influence of cannabis. Questions include report of number of times of driving under different levels of cannabis use. Response values will be summed for a total score.

    Response scale:

    0 Never

    1. 1-2 times
    2. 3-5 times
    3. 6-10 times
    4. 10+ times

  4. Change in other drug use as measured by items modified from Monitoring the Future survey [ Time Frame: 3 and 6 months post-baseline ]

    Items from the Monitoring the Future Survey will be used to assess past 30 day use of 9 other substances - substances used and number of times of use. Response values will be summed for a total score.

    Response scale:

    0 0 Occasions

    1. 1-2 Occasions
    2. 3-5 Occasions
    3. 6-9 Occasions
    4. 10-19 Occasions
    5. 20-39 Occasions
    6. 40 or More Occasions

  5. Change in frequency of alcohol consumption as reported on the Timeline Follow-Back (TLFB) [ Time Frame: 3 and 6 months post-baseline ]
    30-day TLFB self-report will be used to assess total number of days of alcohol consumption.

  6. Change in quantity of alcohol consumption as reported on the Timeline Follow-Back (TLFB) [ Time Frame: 3 and 6 months post-baseline ]
    30-day TLFB self-report will be used to assess the quantity of alcohol consumed.
