The disruption of marijuana intoxication.

Ninety-six males Ss were divided into four drug conditions; coltsfoot, placebo, marijuana low dose, and marijuana high dose. Half of the Ss smoked marijuana while listening to music in a relaxing environment, and half smoked marijuana in the same environment but had two 10-min periods of aversive-noise superimposed over the music. A subjective measure of intoxication demonstrated significant drug and environmental group effects with suppression of self-report of intoxication being especially strong for the marijuana low dose noise group. The usual positive correlation between subjective measures and pulse rate measures of marijuana intoxication was interfered with by the noise effect. Although subjective ratings were suppressed, the noise group demonstrated significantly higher pulse rates than the music group. The results are discussed in terms of the effect of extraneous factors on marijuana intoxication, the significance of dosage in this type of research, and the nature of marijuana intoxication.
