Drugs known to cause addiction include both legal and illegal drugs as well as prescription or over-the-counter drugs, according to the definition of the American Society of Addiction Medicine. Stimulants (psychic addiction, moderate to severe; withdrawal is purely psychological and psychosomatic): Amphetamine and methamphetamine Cocaine Nicotine Caffeine Sedatives and hypnotics (psychic addiction, mild to severe, and physiological addiction, severe; abrupt withdrawal may be fatal): Alcohol Barbiturates Benzodiazepines, particularly flunitrazepam, triazolam, temazepam, and nimetazepam Z- drugs like Zimovane have a similar effect in the body to Benzodiazepines. Methaqualone and the related quinazolinone sedative-hypnotics Opiate and opioid analgesics (psychic addiction, mild to severe, physiological addiction, mild to severe; abrupt withdrawal is unlikely to be fatal): Morphine and codeine, the two naturally occurring opiate analgesics Semi-synthetic opiates, such as heroin (diacetylmorphine; morphine diacetate), oxycodone, buprenorphine, and hydromorphone Fully synthetic opioids, such as fentanyl, meperidine/pethidine, and methadone
Addictive drugs also include a large number of substrates that are currently considered to have no medical value and are not available over the counter or by prescription.
Several theories of drug addiction exist, some of the main ones being genetic predisposition, the self-medication theory, and factors involved with social/economic development. It has long been established that genetic factors along with social and psychological factors are contributors to addiction. A common theory along these lines is the self-medication hypotheses. Epidemiological studies estimate that genetic factors account for 40-60% of the risk factors for alcoholism. Similar rates of heritability for other types of drug addiction have been indicated by other studies (Kendler,1994). Knestler hypothesized in 1964 that a gene or group of genes might contribute to predisposition to addiction in several ways. For example, altered levels of a normal protein due to environmental factors could then change the structure or functioning of specific brain circuits during development. These altered brain circuits could change the susceptibility of an individual to an initial drug use experience. In support of this hypothesis, animal studies have shown that environmental factors such as stress can affect an animal's genotype.
The phenomenon of drug addiction has occurred to some degree throughout recorded history (see "Opium"). Modern agricultural practices, improvements in access to drugs, advancements in biochemistry, and dramatic increases in the recommendation of drug usage by clinical practitioners have exacerbated the problem significantly in the 20th century. Improved means of active biological agent manufacture and the introduction of synthetic compounds, such as methamphetamine are also factors contributing to drug addiction.
Depending on the jurisdiction, addictive drugs may be legal only as part of a government sponsored study, illegal to use for any purpose, illegal to sell, or even illegal to merely possess.
Most countries have legislation which brings various drugs and drug-like substances under the control of licensing systems. Typically this legislation covers any or all of the opiates, amphetamines, cannabinoids, cocaine, barbiturates, benzodiazepines, anesthetics, hallucinogenics, derivatives and a variety of more modern synthetic drugs. Unlicensed production, supply or possession is a criminal offence.
Usually, however, drug classification under such legislation is not related simply to addictiveness. The substances covered often have very different addictive properties. Some are highly prone to cause physical dependency, while others rarely cause any form of compulsive need whatsoever. Also, under legislation specifically about drugs, alcohol, caffeine and nicotine are not usually included.
Although the legislation may be justifiable on moral or public health grounds, it can make addiction or dependency a much more serious issue for the individual: reliable supplies of a drug become difficult to secure, and the individual becomes vulnerable to both criminal abuse and legal punishment.
