What This Study Found

People using CBD+THC products showed significantly higher medicinal and recreational cannabis demand than those using THC or CBD alone (all p<0.001), and 65.2% of participants would try medicinal cannabis if legalized vs. 62.1% for recreational.

Key Numbers

N=1,492 aged 16-30; 65.2% would try medicinal cannabis; 62.1% would try recreational; CBD+THC users had higher demand than both THC-only and CBD-only (all p<0.001); men reported higher demand than women (all p<0.023)

How They Did This

Cross-sectional study of 1,492 Spanish participants aged 16-30 using two Marijuana Purchase Tasks to estimate demand for medicinal and recreational cannabis, with bivariate analyses and split-plot ANOVAs across CBD, THC, and CBD+THC user groups.

Why This Research Matters

As Spain and other countries consider legalization, understanding that existing CBD/THC product users form a ready consumer base helps predict market dynamics and target prevention efforts.

The Bigger Picture

The growing over-the-counter CBD market may serve as a gateway to broader cannabis use if legalization occurs, suggesting prevention programs should proactively target existing CBD consumers.

What This Study Doesn't Tell Us

Hypothetical scenario may not reflect actual behavior; Spanish sample may not generalize; young adult sample; cross-sectional design; self-reported cannabis use categories; no measure of actual purchasing behavior.

Questions This Raises

  • ?Would actual purchasing behavior match hypothetical demand?
  • ?How would pricing affect uptake?
  • ?Do these patterns hold in countries that have already legalized?

Frequently Asked Questions

Would more people use cannabis if it were legalized?

This Spanish study suggests yes — about 65% of young adults said they would try medicinal cannabis if legal, with existing CBD product users being most likely to adopt cannabis use.

Does using CBD products predict future cannabis use?

People already using both CBD and THC over-the-counter products showed significantly higher demand for both medicinal and recreational cannabis than those using either substance alone.
