Brief summary
Researchers at the University of Colorado Anschutz Medical Campus, Colorado School of Public Health, and Injury & Violence Prevention Center want to learn more about how people are affected by cannabis in different ways. The study will use a driving simulator to compare the driving performance of adults who use cannabis daily, occasionally or have not recently used cannabis.
