Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The legalization of recreational marijuana use and sales in Alaska, Colorado, Oregon, and Washington State is a dramatic change in U.S. substance abuse policy that places a priority on developing regulatory and enforcement systems that prevent distribution of retail recreational marijuana to minors. Responsible marijuana vendor training, modeled after effective responsible alcoholic beverage training, has the potential to help the states prevent distribution to minors. This research will produce a responsible marijuana vendor training provided by a third party, not the cannabis industry, and test its effectiveness with retail recreational marijuana licensees and employees in Colorado, Oregon, and Washington State.
