Narcotics and Other Dangerous Substances

Narcotics addiction. Some sub­stances are even more dangerous than alcohol. These are drugs that dull a person's senses and cause him to be­come so dependent on drugs that he will cheat, beg, steal, or even kill to maintain his supply. These drugs, called narcotics, make the user both physically and mentally dependent on them.

Why do people become addicts? People become addicts for many rea­sons. Some people take their first dose of drugs for the "kicks" and feelings of joy that the first few doses bring. A few others become addicts because they become dependent on drugs that were prescribed to ease the pain of an illness or surgical operation. This group is very small, however.

Almost all narcotics addicts use drugs to escape reality. They are men­tally ill, as well as physically depen­dent on drugs. They cannot face real life so they escape into the dream world, where they can ignore the prob­lems and responsibilities of life.

Synthetic drugs. Two types of man-made drugs are also creating serious problems in the United States. These are the barbiturates (bar bich' ə rāts) and amphetamines (am fet' ə mēnz). These two compounds are often used under medical advice. But their use by persons without a doctor's supervision is dangerous. Because both drugs are relatively easily obtained, they are a menace to people who might be tempted to misuse them.
