Maximum symptom relief when using inhaled, dried Cannabis flower by THC and CBD levels. a Symptom relief by CBD and THC level in overall sample. b Symptom relief by THC level by symptom type. c Symptom relief by CBD level by symptom type. Notes: Adjusted maximum symptom relief is reported, which refers to covariate-adjusted change in symptom severity (minimum symptom level reported within 4 h after session initiation minus the starting symptom level) and was obtained from a user-level fixed effects model controlling for subtype, inhalation method, and starting symptom level. Tetrahydrocannabinol (THC) and cannabidiol (CBD) are measured in %/dry wt. CBD categories are controlled for in the THC figure and THC categories are controlled for in the CBD figure. Potency levels represent percentage of labeled, laboratory-tested dried weight
