❚ To feel good. Most abused drugs produce intense feelings of pleasure. This initial sensation of euphoria is followed by other effects, which
differ with the type of drug used. For example, with stimulants such as cocaine, the “high” is followed by feelings of power, self-confidence, and
increased energy. In contrast, the euphoria caused by opiates such as heroin is followed by feelings of relaxation and satisfaction.
❚ To feel better. Some people who suffer from social anxiety, stress-related disorders, and
depression begin abusing drugs in an attempt to lessen feelings of distress. Stress can play a major
role in beginning drug use, continuing drug abuse, or relapse in patients recovering from addiction.
❚ To do better. The increasing pressure that some individuals feel to chemically enhance or
improve their athletic or cognitive performance can
similarly play a role in initial experimentation and
continued drug abuse.
❚ Curiosity and “because others are doing it.”
In this respect adolescents are particularly vulnerable
because of the strong influence of peer pressure; they
are more likely, for example, to engage in “thrilling”
and “daring” behaviors.
