“Cannabis is commonly used to alleviate symptoms of negative affect. However, a paucity of research has examined the acute effects of cannabis on negative affect in everyday life.
The current study provides a naturalistic account of perceived changes in symptoms of depression, anxiety, and stress as a function of dose and concentration of Δ9tetrahydrocannabinol (THC) and cannabidiol (CBD).
Cannabis is commonly used to alleviate depression, anxiety, and stress. Indeed, one of the most commonly reported motives for cannabis use is to cope with stress, with 72% of daily cannabis users reporting use of cannabis to relax or relieve tension.
Results from the present study indicate that medical cannabis users report a substantial and significant reduction in symptoms of negative affect shortly after using cannabis.”
