Cannabis Effects on Sleep, Circadian Rhythms, and Light Sensitivity in Young Adults

Description

Researchers will compare sleep, circadian phase, and light sensitivity within regular cannabis users before, during, and after a cannabis discontinuation protocol; researchers will also compare sleep, circadian phase, and light sensitivity between regular cannabis users and control non-cannabis users.

Participants will:

1. Participate in a 1-week baseline period consisting of at-home monitoring (sleep diaries, actigraphy, EEG headband).
2. Participate in a 2-night lab visit consisting of circadian phase and light sensitivity assessment.
3. Participate in a 4-week cannabis discontinuation protocol (cannabis users only).
4. Participate in a second 2-night lab visit after the discontinuation protocol (cannabis users only).
