Cannabis THC Potency, Metabolism, and Cognitive Impairment in Young Adults

Description

The goal of this interventional study is to determine the impact of high potency THC product use on cognitive function of young adults aged 21-25. The main question it aims to answer is: will cannabis users who switch to less potent THC products demonstrate improved cognitive function compared to baseline? Other questions this study aims to answer include: * Can researchers accurately assess THC consumption among frequent cannabis users? * Can researchers effectively incentivize cannabis users to use less potent THC products? * Do genetic variations in THC metabolism impact urinary THC excretion? * Do genetic variations in THC metabolism impact cognitive performance in cannabis users? * Are quantitative urinary THC values predictive of cognitive impairment? * How can researchers use research findings to inform harm reduction practices for people who use cannabis? Participants will submit blood and urine samples and be incentivized to use less potent THC products.

Conditions
