How Indica, Sativa, and Hybrid labels affect what people expect and feel from cannabis
Effects of Cannabis Species Labeling and Marketing on Perceptual, Subjective and Objective Use Outcomes
This project looks at whether labeling cannabis as Indica, Sativa, or Hybrid changes what adults expect, how they feel right after using it, and how they perform on tasks.

What this research studies
If you join, you'll be an adult (21+) who is shown cannabis products with different species labels and marketing claims and asked about your expectations. You may use or sample products in a controlled setting and report how you feel afterward. Researchers will also measure objective short-term effects such as performance on tasks related to attention or driving. The goal is to see whether labels alone change perceptions, subjective effects, and real-world safety-related behaviors.
Who could benefit from this research
Good fit: Adults aged 21 or older who use or might use recreational cannabis are the ideal candidates for participation.
Not a fit: People under 21, those who do not use cannabis, or whose cannabis use is strictly medical may not get direct benefit from this project.
Why it matters
Potential benefit: If successful, this work could lead to clearer labeling and marketing rules that help people make safer choices about cannabis use.
How similar studies have performed: Research in tobacco and other consumer products shows labeling can change perceptions, but controlled experiments specifically testing cannabis species labels are limited and relatively new.
