Addiction is a condition that results when a person ingests a substance (alcohol, cocaine, nicotine) or engages in an activity (gambling) that can be pleasurable but the continued use of which becomes compulsive and interferes with ordinary life responsibilities, such as work or relationships, even health. Users may not be aware that their behavior is out of control and causing problems for themselves and others.

Experimentation • The first stage, experimentation, is the voluntary use of alcohol or other drugs. Many times it involves teens going to a party and drinking or popping pills in order to fit in. Sometimes, the person experimenting is trying to forget about or escape from an issue. An older person may start drinking to cope with depression after losing a job. Experimentation may even include a teenager taking their mom’s prescription painkillers to cope with an injury from a sports activity. At the time the substance seems to solve the problem. The person takes more, and moves from experimentation to regular use, the next stage. Curiosity.
