Cannabis Demand Measures Predict How Much Young Adults Will Use Three Months Later
Both current and projected future cannabis demand predicted use frequency three months later, suggesting demand-based screening could identify at-risk young adults.
Quick Facts
What This Study Found
Demand measures were stable across 3 months. Participants accurately projected future demand. Both current and projected demand predicted 3-month cannabis use frequency.
Key Numbers
Three MPT timepoints compared; demand stable; both current and projected predicted future use.
How They Did This
Prospective cohort. Young adult cannabis users completed current and projected Marijuana Purchase Tasks at baseline, then reassessed at 3 months.
Why This Research Matters
A simple purchase task can forecast cannabis use three months out, enabling potential early intervention.
The Bigger Picture
Extends behavioral economic purchase tasks from cross-sectional to prospective prediction of substance use.
What This Study Doesn't Tell Us
Sample size not detailed. Short follow-up. Hypothetical purchase scenarios.
Questions This Raises
- ?Could MPT-based screening enable early intervention?
- ?Does projected demand add value beyond current demand?
