In some cases criminal or anti-social behaviour occurs when the person is under the influence of a drug, and long term personality changes in individuals may occur as well. Drugs most often associated with this term include: alcohol , amphetamines , barbiturates , benzodiazepines , cannabis , cocaine , hallucinogens , methaqualone , and opioids.
