• The effect of marijuana on affective changes and interpersonal skills, including empathy, acceptance, warmth, and genuineness, was studied in 20 dyadic relationships in which the experimental subject smoked marijuana containing 6 mg of delta-9-tetrahydrocannabinol and a placebo in separate trials. Marijuana caused a relative decrease in the ratings of the interpersonal skills of the experimental subjects and decreased affective resonance between the experimental subjects and their partners.
