AI Summary

Researchers have developed a new tool called the Edibles Marijuana Purchase Task (eMPT) to measure how much people value cannabis edibles and their willingness to pay for them at different price points. This fills an important gap in cannabis research, as previous demand assessment tools only measured interest in cannabis flower (traditional smoking products), leaving researchers without a way to study the growing market of edibles. The study validated the eMPT across two independent samples totaling 205 participants who regularly use cannabis edibles, examining whether the tool accurately reflects real purchasing behavior and cannabis use patterns.

The eMPT proved to be a highly valid and reliable measurement tool. Results showed that individual demand patterns were consistent and predictable, with multiple measures from the eMPT strongly correlating with each other and with existing cannabis use assessments. Importantly, the tool successfully identified individuals engaging in hazardous cannabis use, showing that people with problematic use patterns displayed higher consumption intensity and willingness to pay, while showing lower price sensitivity. The eMPT also correlated meaningfully with standard cannabis use disorder screening tests and actual spending on cannabis products, suggesting it could be valuable for clinicians and researchers.

This validation study has practical implications for both scientific research and real-world applications. With cannabis edibles becoming increasingly prevalent in legal markets, having a validated tool to measure edible-specific demand will help researchers better understand consumption patterns, identify at-risk users, and develop targeted interventions. The findings also suggest that future research should develop similar assessment tools for other emerging cannabis formulations, as the market continues to expand with novel products beyond traditional flower and edibles.

📄 Original Abstract

The traditional Marijuana Purchase Task (MPT) assesses hypothetical demand (i.e., relative value) for cannabis flower across escalating prices and has been related to cannabis use, cannabis expenditure, and cannabis use disorder symptoms. However, the MPT is specific to demand for cannabis flower, resulting in limited utility for individuals who endorse the use of other cannabis formulations, including edibles. The present investigation aimed to validate a novel measure of cannabis edible demand: the Edibles MPT (eMPT). Data were drawn from two samples (i.e., laboratory: n = 74; crowdsourced: n = 131) who endorsed use of cannabis edibles. Participants completed the eMPT, as well as key cannabis use outcome measures including the Cannabis Use Disorders Identification Test-Revised and cannabis expenditures. Demand data from the eMPT were highly systematic and prototypical across samples. Individual-level demand curves showed substantial variability in consumption. Multiple eMPT indices were significantly intercorrelated (laboratory: |rs| = .43-.93; crowdsourced: |rs| = .36-.89), correlated with corresponding MPT indices (laboratory: |rs| = .52-.69; crowdsourced: |rs| = .47-.74), and associated with Cannabis Use Disorders Identification Test-Revised scores and cannabis expenditures (laboratory: |rs| = .24-.54; crowdsourced: |rs| = .23-44). Additionally, the eMPT differentiated participants in the crowdsourced sample based on hazardous cannabis use via the Cannabis Use Disorders Identification Test-Revised; participants exhibiting hazardous use showed significantly greater intensity, breakpoint, and Omax and lower elasticity (ps < .03; ds .18-.67). These findings demonstrate that the eMPT is a valid assessment of cannabis edible demand and fulfills an unmet need in the cannabis demand literature for edible-specific purchase tasks. Subsequent research should continue to develop purchase tasks for other increasingly prevalent cannabis formulations due to the proliferation of novel cannabis products in the recreational market.
