Study Summary
The investigators will follow probability-based cohorts of adult non-medical marijuana users (N=1,500; ages 21+) and susceptible adolescents and young adults (AYA) users (N=1,000; ages 15-20) over four years. The investigators will use a prospective survey to collect marijuana use information and will conduct volumetric choice experiments (VCEs) where participants choose quantities to purchase among three legal product prototypes: flower, edible, and concentrate; and one illegal flower product, under simulated retail marijuana tax structures. The presentation of edibles and concentrates will change over time to capture the range of product varieties in the market and to accommodate new products and characteristics as they evolve. Choice experiments including VCEs use a series of manipulations as a measurement device to elicit preferences for products and consumption. Therefore, the experimental design is within-subjects with repeated measures, which allow for causal identifications of the impact of design attributes (e.g., tax bases and rates) on preference and consumption outcomes. The attributes and levels are selected to reflect THC levels in the market, existing (weight, price, tiered price by forms) and novel (potency) tax bases, existing (10%-40% of retail price or equivalent in other bases) and potential (high 60% and 80% of retail prices or equivalent) tax rates, and price distribution for each product. Price distribution levels (5 to 95 percentiles) will come from our price data collection and will be updated over time and vary by participants' state and locality of residence. Before the experiment, study personnel will instruct participants 1) how to answer the choice experiment question, including considering their weekly expenditures when answering VCE questions; 2) that there is no access to other products, no stockpiling, no selling or giving away products to others, etc., to ensure that participants choose products that reflect their usual purchase p
Primary Outcome
Number of units that participants intend to purchase, if taxes and prices are set at a certain level.
