I. Marijuana causes behavioral changes A. Chronic Marijuana users become more aggressive during withdrawal. People who have smoked marijuana daily for many years display more aggressive behavior when they stop smoking the drug, according to a new study by researchers at Harvard Medical School. The study, funded by the National Institute on Drug Abuse (NIDA), National Institutes of Health, is further evidence that a withdrawal syndrome is associated with abstinence from long-term marijuana use, and suggests that aggressive behavior is part of this syndrome. Human and animal studies conducted since the early 1970 s have suggested the existence of a marijuana withdrawal syndrome, characterized by insomnia, restlessness, loss of appetite, and irritability. " This syndrome although less dramatic than the withdrawal syndrome associated with alcohol, opiate, or cocaine withdrawal may contribute to relapse among those dependent on marijuana, " says NIDA Director Dr.
Alan I. Lesser. " People addicted to marijuana may continue to use the drug at least partly to prevent the onset of withdrawal symptoms. Identifying the exact nature of this syndrome is crucial to developing treatment strategies for those attempting to stop their marijuana use. " The Harvard study, using a computer test of aggressive behavior, compared 17 long-term heavy users of marijuana with 20 people who were infrequent or former smokers. All of the volunteers were abstaining from the use of marijuana and all other drugs of abuse during the study. To avoid any suggestive influences, the investigators did not reveal to the volunteers that their aggressive behavior was being studied. Instead, the volunteers were told that they were participating in a test designed to measure movements and a variety of physiological characteristics, such as pulse rate and body temperature.
They were also told that another volunteer of the same sex was sitting in another experimental chamber and would be participating in the test with them. Facing each volunteer in the experimental chamber was a computer monitor and a response panel. On a panel were two buttons, labeled A and B. Pressing A 100 times allowed the volunteer to gain 1 point, which was worth 50 cents. Pressing B 10 times subtracted 1 point from the other participant, who, in actuality, was not a person but a computer. Three 1 -second beeps signaled that the " opponent" was subtracting 1 point from the volunteer.
The researchers labeled the pressing of B as an aggressive response, and the point subtractions from the volunteers as provocations. The volunteers participated in one of these sessions on each of five different occasions: at the beginning of the study, and at days 1, 3, 7, and 28 of abstinence. Results showed that the current marijuana users became significantly more aggressive, as indicated by the number of times they pressed B, on days 3 and 7 of withdrawal, as compared to the infrequent of former marijuana users.
