Consequences of Cannabis Use as Measured by the Marijuana Adolescent Consequences Questionnaire Using Dichotomous Response Scale as Previously Described Throughout This Trial Registration. Primary · 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.

Social Media Intervention	10.1	± 5.7

Perceived Risk of Cannabis Use as Measured by 2 Modified Items From the Monitoring the Future Survey Secondary · 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.

Group	Value	95% CI
Social Media Intervention	3.1	± 1.1
Control	3.5	± 1.1

Cannabis Impaired Driving as Measured by 5 Items From the Modified Young Adult Driving Questionnaire Secondary · 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. In the PAST 3 MONTHS...how many times did you drive within one hour after using marijuana or marijuana products containing THC? * how many times did you drive while a little high on marijuana or marijuana products containing THC? * how many times did you drive while very high on marijuana or marijuana products containing THC? * how many times did you drive when you knew your use of marijuana/marijuana pro
