The authors used several indices to assess the relationship between
marijuana and hostility as both inner affect and verbal behavior in a
small-group setting. Marijuana subjects reported a small but statistically
significant decrease in hostile feelings after the introduction of a
frustration stimulus. They also showed significantly less verbal hostility
than placebo subjects both before and after introduction of a frustration
stimulus. The authors note that research findings on marijuana and
hostility are not consistent and suggest a multidetermined relationship
based on dose, environment, nature of the frustration stimulus, and
intraindividual factors.Abstract Teaser
