Many drugsbromides, morphine, cocaine, hashish, marijuana, mescaline, scopolamine, di-isopropyl fluorophosphate, ACTH, pervitin, sodium amytal, lysergic acid, reserpine and chlorpromazine are known to have marked effects on the mental processes of the individuals who receive them. These effects are varied and cannot be discussed here. Suffice it to say that some drugs produce symptoms which resemble those observed in mental disease others work in the opposite direction.

There is no evidence of any -weight regarding the mental and moral injuries from the moderate use of these drugs. Moderation does not lead to excess in hemp any more than it does in alcohol. Regular, moderate use of ganja or bhang [forms of marijuana] produces the same effects as moderate and regular doses of whiskey. ... 

Cocaine acts similarly to amphetamine with regard to its ability to enhance the effects of the catecholamines and serotonin at the synapse. The actions of cocaine on the brain lead to increased alertness, reduced hunger, increased physical and mental endurance, increased motor activity, and an intensification of most normal pleasures. This last feature may explain why so many claim that cocaine enhances emotional and sexual feelings. Cocaine abusers usually co-administer other drugs that are brain depressants (e.g., alcohol, heroin, or marijuana) to decrease the unpleasant hyperstimulant aspects of cocaine. 

Many researchers have studied the relationship between marijuana and mental illness. Early twentieth century proponents of marijuana prohibition in the United States often cited studies showing a link between marijuana and insanity and referred to reports of large numbers of institutionalized mental patients in India and Egypt who had used marijuana. However, since the 1970s, researchers have effectively refuted the claims of a direct link between marijuana use and mental illness. 

Although the major effects of marijuana smoking last only about four to six hours, residual amounts can disrupt some physiological, mental, and emotional functions for a longer period. Urine tests may be positive for as long as ten to fifteen days in daily users and as long as a year in heavy users. Even casual use may result in positive tests for about five to seven days..—...

Dr. Tart s data should lay to rest one of the nastiest myths the Anslinger brigade fostered about marijuana, i.e., that it leads to sexual and other violence. "Loss of control to the point of antisocial actions is reported to be the rarest of all marijuana effects recorded in the Tart study (p. 192). This is consistent with what s been found elsewhere in several NIMH (National Institute of Mental Health) studies. One of the most meticulous of these, The Blumer Report, determined that use of the plant s leaves reduced violence in juvenile delinquents in Oakland.

I have considered lead pollution in detail, but lead is not the only villain in the prenatal environment. Others include methyl-mercury polychlorinated biphenyls (PCBs) dioxins pesticides ionizing radiation and maternal use of alcohol, tobacco, marijuana, and cocaine. These villains can cause a range of behavioral effects from severe mental retardation and disability to subtle changes in mental function that depend on the timing and dose of the chemical agent. Indeed, more than zoo industrial... 

Marijuana/hashish These are cannabis drugs that seem to act as a CNS depressant. The effects are mental relaxation and euphoria and decreased inhibitions. 

Acute and chronic administration of alcohol can inhibit the biotransformation or detoxification of many drugs, such as barbiturates, meprobamate, and amphetamines by liver enzymes. The effect can occur in two opposite ways. Alcohol and cannabinoids effects are additive. Both are CNS depressants. Animal studies indicate that simultaneous administration of alcohol and tetrahydrocannabinol (THC), the psychoactive component of marijuana, increased the tolerance and physical dependence to alcohol. Human studies show that alcohol and THC combination enhanced the impairment of physical and mental performance only, and there is no evidence of any interaction between both drugs. With barbiturates.
