Definition

Drug abuse occurs when a person feels the need to use a drug repeatedly for various reasons. Drug addiction is said to be present when a person compulsively abuses a drug after serious problems related to the drug use have occurred.

What is going on in the body?

Drug abuse is a widespread problem that affects people of all socioeconomic levels. The symptoms of abuse and addiction differ slightly based upon the drug being taken. Drug abuse and addiction cause many health-related and social problems.

What are the signs and symptoms of the condition?

Several of the following symptoms or signs occur when a person is addicted to a drug. The person may:

Physical symptoms vary depending on the drug being abused and the extent of the drug use. The health risks of tobacco, for example, are different than the health risks of drugs such as alcohol or cocaine.

What are the causes and risks of the condition?

The exact reason why some people abuse and become addicted to drugs is not known. There appears to be a complex relationship between biological and environmental factors that leads to abuse and addiction.

What can be done to prevent the condition?

The best prevention available now is education. If a person has any symptoms of drug abuse, it is important to seek help. The earlier the treatment, the better the results.

How is the condition diagnosed?

The condition is diagnosed by asking the person about drug use. If several of the symptoms or signs mentioned above are present, the person is said to be abusing drugs and may become or may already be addicted to drugs.

What are the long-term effects of the condition?

Problems associated with drug addiction vary widely among different people. Long-term use may result in changes in brain function that last long after the person stops using drugs. Tobacco dependence is the number one cause of preventable disease and death in the U.S. Alcohol is not far behind. People with drug dependence can have financial, social, legal, and other personal problems. These may last long after they stop using the drug. Death is fairly common in those with drug dependence due to harmful effects of the drug on the body.

What are the risks to others?

Drug abuse is not contagious and poses no risk to others, but those abusing or addicted to drugs may inflict harm to obtain drugs or while affected by them.

What are the treatments for the condition?

Treatment partly depends on the drug that is used and the personality of the affected person. Treatment is complex. Often it must address the addiction as well as the person's mental and physical health and any work or social problems that occur. Effective treatment may include behavioral therapy, medicines, or some combination of these.

Behavioral therapy helps people: The best drug abuse programs will provide a combination of therapies and services. Successful treatment recognizes or responds to certain important issues.

What are the side effects of the treatments?

Drug abuse is a chronic problem. There may need to be several kinds and numbers of therapies. If medications are used, they may have side effects of their own, or in some cases, the result may be that the person simply switches from one addiction to another.

What happens after treatment for the condition?

Monitoring and therapy are needed at least until a person can function fully and long-term abstinence, or avoidance of drug use, has been achieved. Self-help programs are often useful in keeping a person sober or "clean."

How is the condition monitored?

Monitoring may include the use of drug tests. These can be urine, saliva, or blood tests. Any new or worsening symptoms should be reported to the healthcare professional.
