drugs addict

Drug addiction is a dependence on an illegal drug or a medication. When you're addicted, you may not be able to control your drug use and you may continue using the drug despite the harm it causes. Drug addiction can cause an intense craving for the drug. You may want to quit, but most people find they can't do it on their own.
For many people, what starts as casual use leads to drug addiction. Drug addiction can cause serious, long-term consequences, including problems with physical and mental health, relationships, employment and the law.
You may need help from your doctor, family, friends, support groups or an organized treatment program to overcome your drug addiction and stay drug-free.
