Document Summary
The altering of consciousness by drugs (chapter 7 in myers) Psychoactive drugs: change perception of external (and internal) environment, perhaps change mood. Tolerance: with repeated use, tolerance develops, a larger dose is required to produce the same effect, withdrawal (craving for drug, physical dependence (physical addiction). Physical pain, craving for drug: psychological dependence (psy. addiction). For some drugs (particularly the hallucinogens), there may be negative tolerance: a lower dosage is required to obtain the same initial effect. This might be because some of these drugs linger in the body for a very long time. False claims about addiction: all psychoactive drugs lead to addiction, no! For some there is no addiction (e. g. , lsd). For even highly addictive drugs (alcohol, cocaine, heroin) only 10% will show addiction. Also, those who use drugs medically do not usually become addicted to them: soft drugs (marijuana, hash, etc) lead to hard drugs.
