Review'Legal highs'--novel and emerging psychoactive drugs: a chemical overview for the toxicologist.
'Legal highs' are psychoactive chemicals which are sold from 'head shops', the internet and from street suppliers and may be possessed without legal restriction. An increase in the marketing of these materials has resulted in a corresponding increase in published reports of their adverse effects. However, a lack of primary literature pertaining to their chemistry, pharmacology and toxicology, makes an evaluation of their harm difficult. This review covers the basic chemistry of these novel psychoactive compounds and relates them to endogenous neurotransmitters and existing drugs of abuse. ⋯ 'Legal highs' are gaining in popularity and present clear challenges to toxicologists and society as a whole. Whilst improved use of existing legislation and development of new legislation can be used to reduce the supply of these materials, investment in better education for young people on the harms associated with 'legal highs' is needed.
