NCT03073291

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Change in Pseudo-underage Buyer Purchase Attempts

    Successful purchase attempts of a recreational marijuana product by underage-appearing pseudo-patron buyer will be assessed by pseudo-patron teams of a buyer and observer. The observer will enter the retail recreational marijuana store, showing a valid ID indicating they are 21 or older. The buyer will attempt to enter the store. If asked for an ID, the buyer will say they do not have a driver's license (acceptable form of ID) and offer instead a college ID (unacceptable form of ID). If permitted to enter store, buyer will ask to purchase pre-rolled joints. When the clerk asks the buyer to make payment, the buyer will say they do not have enough money and leave the store. The observer and buyer will record the outcome of the purchase attempt. No actual recreational marijuana product will be purchased.

    Baseline, 3-month follow-up, and 9-month follow-up

Secondary Outcomes (1)

  • Change in State-required Store Signage

Study Arms (2)

Responsible Marijuana Vendor Training

EXPERIMENTAL

The TrainToTend online responsible marijuana vendor training teaches responsible sales practices in five modules: Module 1, The Laws; Module 2, ID Checking; Module 3, Health Effects; Module 4, Customer Service, and Module 5, Rules of the Trade. The training content will be conveyed using online educational activities providing application and feedback such as in tabs with appropriate graphics and interactive simulations where users apply the skill and receive informative/corrective feedback.

Behavioral: Responsible Marijuana Vendor Training

Usual and Customary Sales Practices Training

NO INTERVENTION

Usual and customary training in retail sales practices delivered to employees at retail recreational marijuana stores by store managers. Some retail stores in Colorado may receive responsible marijuana vendor training of some type from another state-approved training provider. Thus, we consider the outlets in the control group to have usual and customer sales training but not to be entirely untrained.

Interventions

Responsible Marijuana Vendor TrainingBEHAVIORAL

Employees at retail recreational marijuana stores assigned to the the responsible marijuana vendor training will register them on TrainToTend online training program, create a user profile, and complete the training within four weeks from initial registration. Personnel who complete the training will receive a certificate of completion. New hires at the stores during the trial will be registered and complete the training within four weeks of commencing work. Separate versions of the training will be available reflecting differences in the laws/regulations on recreational marijuana sales in Colorado, Oregon, and Washington State and the content will be reviewed and approved by state regulators.

Data Sharing

IPD Sharing
Will not share

At the conclusion of the project Klein Buendel Inc. will initiate a data sharing plan to make data from this project publicly available via archive files and publish reports describing study procedures in detail in peer-reviewed academic journals. Public data sets will be de-identified so that they are free of all identifiers that would permit linkages to individual research participants and of variables that could lead to deductive disclosure of the identity of individual participants. Individuals wishing to use this data will be required to fill out the KB Data Sharing Request Form, which asks for information on the type of data being requested, anticipated data use, research questions, study design, variables, analysis plan, and IRB approval.
