Highly potent cannabis concentrates are widely available and associated with affective disturbance and cannabis use disorder. Little is known about the effects of concentrated Δ9-tetrahydrocannabinol (THC) and cannabidiol (CBD) and their relationship to long-term affect. We explored how baseline affective symptoms (anxiety and depression) relate to acute (i.e., immediate or short-term) subjective mood and intoxication effects during naturalistic use of cannabis concentrates. Fifty-four cannabis users (48% female; M age = 29.87) were assigned to ad libitum use of either a THC-dominant (84.99% THC and THCa, < 1% CBD) or CBD-dominant (74.7% CBD, 4.1% CBDa, 4.5% THC and THCa) concentrate. Individuals were assessed at baseline and before, immediately after, and 1 hr after naturalistic use of their assigned product. Models regressed each outcome on time, product condition, baseline affective symptoms, and their interactions. An interaction emerged between condition and baseline depression symptoms on positive mood ( F = 9.47, p < .005); higher depression symptom level was associated with higher positive mood with THC-dominant product use. There was an interaction between condition, baseline depression symptoms, and time on negative mood ( F = 5.55, p < .01); negative mood decreased with CBD-dominant product use for all depression symptom levels but increased with THC-dominant product use at high levels. Finally, there was an interaction between condition and time on intoxication ( F = 3.72, p = .03); the THC-dominant condition was more intoxicated postuse than the CBD-dominant condition. This novel exploratory study suggests that baseline affect moderates the acute effects of ad libitum use of THC and CBD concentrates such that preexisting affective symptoms modulate the intensity of subjective drug experiences.
