Researchers from Washington State University found that adults reported a significant reduction in depressive symptoms with just a single puff of medical marijuana that was high in cannabidiol (CBD) and low in tetrahydrocannabinol (THC).

The team also found that at least 10 puffs of marijuana high in both CBD and THC led to significant reductions in self-reported stress, while two puffs of cannabis with any level of CBD or THC led to a reduction in anxiety.

“Existing research on the effects of cannabis on depression, anxiety, and stress are very rare,” says Cuttler, “and have almost exclusively been done with orally administered THC pills in a laboratory.”

For symptoms of stress, at least 10 puffs of high-CBD, high-THC cannabis produced the greatest benefit.

To reach their findings, Cuttler and team analyzed data from Strainprint, a Canadian app used to track medical cannabis use and the symptom severity of almost 280 medical conditions.

For this study, Cuttler and colleagues assessed around 12,000 entries of adults who used the app to track symptoms of anxiety, stress, and depression. Around 20 minutes after drug administration, users are required to report symptom severity on a scale ranging from 1–10.
