What this trial studies

This study aims to explore the effects of cannabis on mental and physical states, focusing on mood, cognition, perception of temperature and pain, and heart rate. Participants will engage in two in-person visits over the course of one week, completing various tasks that will take approximately 2.5 hours in total. The study will utilize water temperature variations as part of the experimental interventions to assess these effects.

Who should consider this trial

Good fit: Ideal candidates are adults aged 21-65 who regularly use cannabis for coping and have experience with both CBD and THC products.

Not a fit: Patients with substance use or psychotic disorders, or those who have recently used other illicit drugs, will not benefit from this study.

Why it matters

Potential benefit: If successful, this research could provide insights into how cannabis use influences emotional and sensory experiences, potentially guiding therapeutic applications.

How similar studies have performed: While there have been studies on cannabis effects, this specific focus on perceptual influences is relatively novel and less explored.
