Investigating Real-world Stress-related Mechanisms in Heavy Cannabis Users

During intake, a research assistant will demonstrate how to place the Heart Rate Variability monitor and provide instructions on completing the saliva samples at home. Participants will wear the Heart Rate Variability monitor for three consecutive, randomly selected days twice (72 hours each). Participants will be provided with six saliva sample collection tubes per day with explicit directions on when the saliva sampling should occur (hours since waking: +0, +1, +2, +4, +6, +10 hours, and before going to sleep). Participants will also complete a subjective report using similar questions included in the survey prompts at the same scheduled time as the saliva sample. All participants will complete a total of 6 such days during the study.
