In contrast to schizophrenic psychosis, acute psychosis
induced by amphetamines seems to have a faster recovery
[60-63], and appears to resolve with abstinence,
although the recovery may be incomplete [43]. Japanese
researchers have argued that psychosis induced by
amphetamines could, in fact, be of much longer duration,
up to several years [64-66]. This research
describes spontaneous psychotic relapses in the long
term after remittance of psychosis (“flashbacks”), a
phenomenon acknowledged in the popular folk culture
in the USA and Europe, but much less researched
