What is drug addiction? Addiction is a chronic, often relapsing brain disease that causes compulsive drug seeking and use despite harmful consequences to the individual that is addicted and to those around them. Drug addiction is a brain disease because the abuse of drugs leads to changes in the structure and function of the brain. Although it is true that for most people the initial decision to take drugs is voluntary, over time the changes in the brain caused by repeated drug abuse can affect a person’s self control and ability to make sound decisions, and at the same time send intense impulses to take drugs.

It is because of these changes in the brain that it is so challenging for a person who is addicted to stop abusing drugs. Fortunately, there are treatments that help people to counteract addiction’s powerful disruptive effects and regain control. Research shows that combining addiction treatment medications, if available, with behavioral therapy is the best way to ensure success for most patients. Treatment approaches that are tailored to each patient’s drug abuse patterns and any co-occurring medical, psychiatric, and social problems can lead to sustained recovery and a life without drug abuse.

Similar to other chronic, relapsing diseases, such as diabetes, asthma, or heart disease, drug addiction can be managed successfully. And, as with other chronic diseases, it is not uncommon for a person to relapse and begin abusing drugs again. Relapse, however, does not signal failure—rather, it indicates that treatment should be reinstated, adjusted, or that alternate treatment is needed to help the individual regain control and recover.

Introduction You may be hooked emotionally and psychologically. You may have a physical dependence, too. If you have a drug addiction — whether to a legal or illegal drug — you have intense cravings for it. You want to use the drug again and again. When you stop taking it, you may have unpleasant physical reactions.

While not everyone who uses drugs becomes addicted, many people do. Drug addiction involves compulsively seeking to use a substance, regardless of the potentially negative social, psychological and physical consequences. Certain drugs, such as narcotics and cocaine, are more likely to cause physical dependence than are other drugs.

Breaking a drug addiction is difficult, but not impossible. Support from your doctor, family, friends and others who have a drug addiction, as well as inpatient or outpatient drug addiction treatment, may help you beat your drug dependence.

Abuse and addiction are not the same. Drug abuse always comes before addiction, which is a chronic and treatable disease. Drug abuse starts when your teen makes a conscious decision to take drugs. Used too often, drugs may cause your child to crave the substance. That's because physical changes in the brain take place. Neurons, or brain cells, use chemical messengers called neurotransmitters to "talk" to each other. Drugs interfere with this process by making both temporary and structural changes in brain cells. Mood, memory, thinking and even motor skills such as walking may be affected. When this happens, drug abuse turns into addiction. People who are addicted have a compulsive craving and cannot quit by themselves. Not everyone becomes addicted. But any drug abuse is dangerous.
