Investigated the interaction of psychological and physiological measures of the marihuana intoxicated state. The subjective measure of intoxication was the “How High” Scale, a rating of percentage of the S 's usual “high.” The objective measure was pulse rate, which has been found to be the most consistent physiological indicator of marihuana intoxication. By means of biofeedback techniques, S s in the experimental group were taught to increase voluntarily pulse rate when intoxicated. A control group attended to feedback, but did not manipulate pulse rate. Group comparisons of the dependent measures demonstrated that while both groups experienced a similar subjective “high,” the experimental group demonstrated a significantly higher pulse rate. This discrepancy between objective and subjective measures demonstrates the complexity of the intoxicated state.
