    the Effects of Marijuana in Users


    I. The Weil-Zinberg Study

    In 1968 Andrew Weil, then a medical student at Harvard University, together with Norman Zinberg, a Harvard psychoanalyst, conducted a series of experiments to determine the basic physical and psychological effects of marijuana on human beings This study, which took place at Boston University, represented the first double-blind experiments with marijuana; until the study was completed, neither the subjects nor the experimenters knew who had been smoking a drug and who had been smoking a carefully disguised placebo.
        Here are the conclusions, as reported in the article, "Clinical and Psychological Effects of Marihuana in Man," Science 162 (13 December 1968):1234-42.
        1. It is feasible and safe to study the effects of marijuana on human volunteers who smoke it in a laboratory.
        2. In a neutral setting persons who are naive to marijuana do not have strong subjective experiences after smoking low or high doses of the drug, and the effects they do report are not the same as those described by regular users of marijuana who take the drug in the same neutral setting.
        3. Marijuana-naive persons do demonstrate impaired performance on simple intellectual and psychomotor tests after smoking marijuana; the impairment is dose-related in some cases.
        4. Regular users of marijuana do get high after smoking marijuana in a neutral setting but do not show the same degree of impairment of performance on the tests as do naive subjects. In some cases, their performance even appears to improve slightly after smoking marijuana.
        5. Marijuana increases heart rate moderately.
        6. No change in respiratory rate follows administration of marijuana by inhalation.
        7. No change in pupil size occurs in short-term exposure to marijuana.
        8. Marijuana administration causes dilation of conjunctival blood vessels.
        9. Marijuana treatment produces no change in blood sugar levels.
        10. In a neutral setting the physiological and psychological effects of a single, inhaled dose of marijuana appear to reach maximum intensity within one-half hour of inhalation, to be diminished after one hour, and to be completely dissipated by three hours.
