Drug abuse is the chronic or habitual use of any chemical substance to alter the body or mind for other than medical purposes. Drugs with potential for abuse include:
* narcotics, such as morphine, opium, heroin and methadone,
* depressants, such as alcohol, barbiturates, and sedatives,
* stimulants, such as cocaine (crack) , speed, and
* hallucinogenic drugs, such as LSD and marijuana.

Alcohol, nicotine or caffeine may also be abused. Anabolic steroids and human growth hormone may be abused by athletes and body builders. Prescription drugs can be abused, if taken in ways they are not directed to be taken.

Some drugs are addictive. This means one can become physically dependent upon them. Withdrawal symptoms will occur in the absence of the drug. Some examples of addictive drugs are heroin, crack and Librium. Other drugs are psychologically habituating. This means that one can become psychologically dependent. But, there will not be withdrawal symptoms if the drug is withheld. An examples of this is marijuana.

Sooner or later, if a person is abusing drugs, it will begin to affect their life. Drug abuse tends to get worse over time. Legal, medical, work and relationship problems may begin to occur. Drug abuse may be a problem, if you or someone you care about is:
* in trouble at work, or school,
* in increased conflict with family and friends,
* putting getting high ahead of other activities,
* not taking care of responsibilities, and
* letting go of activities, hobbies and friendships.

* clergy,
* a school or occupational nurse,
* a school counselor, or
* Employee Assistance Program.
