Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

The investigators will study the harm-reducing effect of hemp-derived CBD in non-treatment-seeking emerging adults who use cannabis regularly. The study will use a novel naturalistic cannabis administration approach, which examines ecologically valid cannabis use utilizing a mobile lab setting to assess the effects of the cannabis products the participants regularly use. The investigators will recruit a sample of emerging adults, half of whom primarily use flower products and half of whom primarily use concentrate products. Individuals will be randomly assigned to hemp-derived CBD or placebo.
