Teenagers are the people that are in the adolescence. Adolescence is a period of the life of changes and discovery.<br />Adolescence<br />
A drug is any substance, solid, liquid or gas, that brings about physical and/or psychological changes. The drugs of most concern in the community are those that affect the central nervous system. They act on the brain and can change the way a person thinks, feels or behaves.<br />Drugs<br />
Beneficial drugs are drugs that in small quantities can cure diseases.<br />Beneficialdrugs<br />
Because they are illegal, there are no price or quality controls on the illicit drugs such as heroin and ecstasy. Various batches of an illegally manufactured drug may have different mixtures of the drug and additives such as poisons, caffeine or even talcum powder.<br />Illegaldrugs<br />
Stimulants act on the central nervous system to speed up the messages to and from the brain. They can make the user feel more awake, alert or confident. Some stimulants are:<br /><ul><li>Ephedrine used in medicines for bronchitis, hay fever and asthma
Hallucinogens <br />Hallucinogens affect perception. People who have taken them may believe they see or hear things that aren't really there, or what they see may be distorted in some way. Hallucinogensinclude:<br /><ul><li>Datura

<ul><li>Biology. The genes that people are born with in combination with environmental influences account for about half of their addiction vulnerability.
Environment. A person's environment includes many different influences from family and friends to socioeconomic status and quality of life in general.
Development. Although taking drugs at any age can lead to addiction, the earlier that drug use begins, the more likely it is to progress to more serious abuse. And because adolescents' brains are still developing in the areas that govern decision making, judgment, and self-control, they are especially prone to risk-taking behaviors, including trying drugs of abuse.</li></ul>Causes ofdrugaddictioninadolescense<br />
