This paper discusses the nature and extent of student drug use, its meaning and significance, society's response to it, and some of the problems resulting from efforts to control it. Drugs are any substance which by its chemical nature affects the structure or function of the living organism. Abuse refers to any use of a non-medically approved drug or of a medically approved drug for non-medically approved purposes. The greatest increase in drug usage is in the use of mood changing drugs, particularly marihuana. Many of the reasons young people use drugs are the same as the reasons for adults using drugs: for fun, to facilitate interaction (social), to feel better, and to relieve boredom. The effects of drugs are varied depending on sex, age, state of health, and individual differences. Whether the outcomes or reactions are good or bad is a value judgment. Much research is needed for more information on drugs and their use. Limiting the supply of a particular drug does not decrease drug use, but rather causes the user to look for another drug. Drug education is badly needed. Furthermore, instead of treating the problem, we are attempting to regulate the symptoms. Perhaps more care in dealing with basic problems or at least identifying these problems will help solve today's drug problems. (KJ)
