Drug abuse has a wide range of definitions related to taking a psychoactive drug or performance enhancing drug for a non-therapeutic or non-medical effect. Some of the most commonly abused drugs include alcohol, amphetamines, barbiturates, benzodiazepines, cocaine, methaqualone, and opium alkaloids.
Drugs like cocaine, methamphetamine, marijuana, heroin, alter gene expression and brain circuitry. Once drug abuse crosses into addiction, the compulsive drug craving, seeking and use occurs. Our featured publications offer a variety of cultural, social, and scientific views on drug abuse.
The use of chemicals to alter the way we feel and see things is one of the oldest activities of the human race. But a person’s use of a drug such as tobacco, alcohol, cannabis or heroin can become uncontrolled, or start to control them. Even when the use of drugs leads to serious physical and mental problems, the person using may still not want to stop. If they do decide to give up, they may then find it’s much harder.
A drug is any chemical that produces a therapeutic or non-therapeutic effect in the body. Chemicals, on the other hand, are a broad class of substances — including drugs — that may or may not produce noticeable effects in the body. Many chemicals (such as tin, lead, gold) have harmful effects on the body, especially in high doses. Most foods are not drugs. Alcohol is a drug — not a food, in spite of the calories it provides. Nicotine is a chemical that is also a drug.

Four levels of drug use are easily identifiable: non-drug use, drug use, drug abuse, and drug dependency.
Non-drug users do not use drugs whatsoever. Drug users use drugs from time to time, typically in the company of others during recreational time. Drug abusers use drugs more readily, at times when sobriety is called for and in such a manner that other life functions or roles are either put at risk or are already compromised. Drug dependent persons use drugs very regularly to the point where there is a physiological dependency. Given physiological dependency, abrupt cessation of the drug results in physical symptoms ranging from agitation to depression to physical pain to death.
Many people regard marijuana and alcohol as innocuous substances when used recreationally from time to time. That is arguable. At the very least, no one became a drug abuser without first becoming a drug user.
Drug abuse is of greater concern however and is more than occasional recreational use. While it may be argued that occasional recreational use is not destructive, problems do develop for those whose more frequent use interferes with psychological, marital, family, social, academic or vocational life. Further, the threshold of drug abuse is readily identifiable when it occurs during non-recreational time; where intoxication overlaps with non-recreational activities; when use or the after-effects of use interfere with any activity. In addition, if drug use is frequently or always associated with recreational activities, then this rises to the level of abuse, as the user is remarkably limited in scope of other healthy recreational activities.
