Why do some people choose to use drugs when they’re so bad for you? The causes of drug addiction are as varied as the amount of drugs that are available for use – both legally and illegally. There is no one cause for drug addiction just like there is no consistent profile of a drug user.
People who have a history of drug use or abuse in their families are at risk for drug addiction problems. It has been proven that children of alcoholics will exhibit addictive tendencies. Children of alcoholics or drug users generally have low self-esteem and see their parents escaping from problems using drugs. When they see this, their minds say that this is the way to act and they themselves become users.
There is also a biological basis for causing drug addiction. Drugs alter the brain’s chemicals and the way the brain functions. Drug addiction creates dependence in the brain by changing the brain’s reward functions – the part that reinforces certain behaviors.
