Both current and projected future cannabis demand predicted use frequency three months later, suggesting demand-based screening could identify at-risk young adults.

Both current and projected demand predicted 3-month use
What the researchers found
Demand measures were stable across 3 months. Participants accurately projected future demand. Both current and projected demand predicted 3-month cannabis use frequency.
Why it matters
A simple purchase task can forecast cannabis use three months out, enabling potential early intervention.
The numbers in context
Three MPT timepoints compared; demand stable; both current and projected predicted future use.
How the study worked
Prospective cohort. Young adult cannabis users completed current and projected Marijuana Purchase Tasks at baseline, then reassessed at 3 months.
What this study cannot tell us
Sample size not detailed. Short follow-up. Hypothetical purchase scenarios.
How to read the evidence
Prospective design with validated measures. Limited detail on sample and effect sizes.
When this study was published
2025 study of prospective cannabis demand-use associations.
The bigger picture
Extends behavioral economic purchase tasks from cross-sectional to prospective prediction of substance use.
Questions still open
- Could MPT-based screening enable early intervention?
- Does projected demand add value beyond current demand?
Common questions
Can you predict future cannabis use?
Can people predict their own future use?
