Brief Summary

Currently, marijuana (MJ) is the most popular illicit drug, but there are few effective interventions to help young adults (age 18 to 25 years) to reduce their MJ intake. In this study, we will develop and initially test a smart phone app designed to promote exercise/physical activity as a positive alternative to MJ use. The app will be tested in an efficacy study in which MJ users are randomly to either receive personalized feedback about MJ use + use the exercise app or personalized feedback only. The results will contribute to knowledge about exercise/physical activity as a strategy for reducing young adults' MJ use and problems.

Conditions

Outcome Measures

Primary Outcomes (2)

• Physical Activity

  Counts based on data collected by accelerometers.

  Change in exercise at 1 month, 3 months, and 6 months after interventionts

• Substance Use

  Change in marijuana use at 1 month, 3 months, and 6 months after intervention

Study Arms (2)

Lifestyle counseling

EXPERIMENTAL

MJ users assigned to this condition will participate in 4 individualized intervention sessions that are based on Motivational Interviewing principles. They will receive personalized feedback on their MJ use and will be provided a smart phone app on which they report their MJ use episodes, which also is designed to promote the use of exercise/physical activity as an alternative to MJ use. Level of Physical activity will be measured using accelerometers.
