Primary Outcome Measures :
  1. Frequency of Cannabis Use as Reported on the Timeline Follow-Back (TLFB) [ Time Frame: 3-months post baseline ]
    30-day TLFB self-report will be used to assess total number of days of cannabis use.

  2. Frequency of Cannabis Use as Reported on the Timeline Follow-Back (TLFB) [ Time Frame: 6-months post baseline ]
    30-day TLFB self-report will be used to assess total number of days of cannabis use.

  3. Quantity of Cannabis Used as Reported on the Timeline Follow-Back (TLFB) [ Time Frame: 3-months post baseline ]
    30-day Timeline Follow-Back (TLFB) self-report will be used to assess quantity (grams) of cannabis consumed.

  4. Quantity of Cannabis Used as Reported on the Timeline Follow-Back (TLFB) [ Time Frame: 6-months post baseline ]
    30-day Timeline Follow-Back (TLFB) self-report will be used to assess quantity (grams) of cannabis consumed.

  5. Consequences of Cannabis Use as Measured by the Marijuana Adolescent Consequences Questionnaire Using Dichotomous Response Scale as Previously Described Throughout This Trial Registration. [ Time Frame: 3-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

    Minimum score =0, maximum = 26. Higher score = more consequences.


  6. Consequences of Cannabis Use as Measured by the Marijuana Adolescent Consequences Questionnaire [ Time Frame: 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

    Minimum score =0, maximum = 26. Higher score = more consequences.



Secondary Outcome Measures :
  1. Perceived Risk of Cannabis Use as Measured by 2 Modified Items From the Monitoring the Future Survey [ Time Frame: 3-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.

    Items are--

    How much do you think people risk harming themselves (physically or in other ways), if they:

    1. Use marijuana or marijuana products occasionally
    2. Use marijuana or marijuana products regularly

    Response options are:

    1. No risk
    2. Slight risk
    3. Moderate risk
    4. 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.


  2. Perceived Risk of Cannabis Use as Measured by Modified Items From the Monitoring the Future Survey [ Time Frame: 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.

    Items are--

    How much do you think people risk harming themselves (physically or in other ways), if they:

    1. Use marijuana or marijuana products occasionally
    2. Use marijuana or marijuana products regularly

    Response options are:

    1. No risk
    2. Slight risk
    3. Moderate risk
    4. 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. Peer Approval/Disapproval of Cannabis Use as Measured by Item Modified From Monitoring the Future Survey [ Time Frame: 3 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

  4. Peer Approval/Disapproval of Cannabis Use as Measured by Item Modified From Monitoring the Future Survey [ Time Frame: 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

  5. Cannabis Impaired Driving as Measured by 5 Items From the Modified Young Adult Driving Questionnaire [ Time Frame: 3 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. Response values will be summed for a total score.
