The aim of this study is to determine the effects of regular cannabidiol (CBD) use on the psychobiological mechanisms of the stress response. This will be achieved by comparing acute stress responses of adults who either use or do not use CBD regularly. Correlates of CBD use, including tobacco use, will be collected.

RECRUITINGChange in subjective states (stress, anxiety, positive affect)
Participants will self-report the extent to which they have felt stressed, overwhelmed, anxious/nervous, cheerful, and happy during the last 30 minutes before acute stress, immediately after acute stress, and after a recovery period. The Subjective States Questionnaire will be used to score responses. The minimum values are 0 (not at all) and the maximum values are 7 (very strongly). Higher scores mean more stress, more anxiety, and more positive affect.
Time frame: 2.5 hours
Change in cardiovascular activity and cortisol
Saliva will be collected (for later cortisol assays) and cardiovascular activity will be measured before, during, and after acute stress.
Time frame: 2.5 hours
