Drug Abuse

Drug abuse is the inappropriate and continued use of drugs, even when they cause work-related, legal, health or family difficulties.

Drug addiction is the long term compulsive consumption of drugs. The user will possibly try to stop using drugs but will return to them repeatedly in spite of the social, physical and emotional damage that they cause.

Drug dependency means that the body begins to need higher doses of the drug to achieve the same effect and to prevent withdrawal symptoms.

Commonly abused drugs include the following: Cocaine, Heroin, Morphine, LSD (Lysergic acid diethylamide), Marijuana, methamphetamines (Speed) , PCP (Phencyclidine, also known as Angel Dust), Ecstasy, GHB ("date rape” drug), Ketamine, steroids, inhalants, prescribed medicines used incorrectly such as opiate pain killers, amphetamines, sleeping pills or anxiolytics (anti-anxiety medicines).

The exact cause of drug abuse and dependency is not known. Nonetheless, there are many theories on the subject. For example, it is possible that some people inherit certain genes which make them more disposed to drug abuse. Another theory suggests that a person learns to consume drugs copying the behavior of others. Additionally, the changes that take place in the brain due to long term drug use can reinforce a person´s desire to continue using drugs.
