Psychoactive drug



A psychoactive drug, psychopharmaceutical, or psychotropic is a chemical substance that changes brain function and results in alterations in perception, mood, or consciousness. These substances may be used recreationally, to purposefully alter one's consciousness, or as entheogens, for ritual, spiritual, or shamanic purposes, as a tool for studying or augmenting the mind. Some categories of psychoactive drugs, which are prescription medicines, have medical therapeutic utility, such as anesthetics, analgesics, hormonal preparations, anticonvulsant and antiparkinsonian drugs or for the treatment of neuro-psychiatric disorders, as hypnotic drugs, anxiolytic and some stimulant medications used in ADHD and some sleep disorders. There are also some psychoactive substances used in the detoxification and rehabilitation programs for psychoactive drug users.Psychoactive substances often bring about subjective (although these may be objectively observed) changes in consciousness and mood that the user may find rewarding and pleasant (e.g. euphoria) or advantageous (e.g. increased alertness) and are thus reinforcing. Substances which are both rewarding and positively reinforcing have the potential to induce a state of addiction – compulsive drug use despite negative consequences – when used consistently in excess. In addition, sustained use of some substances may produce a physical dependence or psychological dependence syndrome associated with somatic or psychological-emotional withdrawal states respectively. Drug rehabilitation aims to break this cycle of dependency, through a combination of psychotherapy, support groups, maintenance and even other psychoactive substances. However, the reverse is also true in some cases, that certain experiences on drugs may be so unfriendly and uncomforting that the user may never want to try the substance again. This is especially true of the deliriants (e.g. Jimson weed) and powerful dissociatives (e.g. Salvia divinorum). Most purely psychedelic drugs are considered to be non-addictive (e.g. LSD, psilocybin, cannabis, mescaline). ""Psychedelic amphetamines"" or empathogen-entactogens (such as MDA and MDMA) may produce an additional stimulant or euphoriant effect, and thus have an addiction potential.In part because of this potential for substance misuse, addiction, or dependence, the ethics of drug use is debated. Restrictions on drug production and sales in an attempt to decrease drug abuse is very common among national and sub-national governments worldwide. Ethical concerns have also been raised about over-use of these drugs clinically, and about their marketing by manufacturers.
