    The chemically-based frame of reference adopted by the UN Single Convention is mistaken in the culturally loaded and falsely “scientific” manner in which it was applied to different plants.

    Within the last decade the hitherto little known psychoactive substance of khat has emerged as a regional and international issue. In the Horn of Africa khat production has spurred an economic boom, but dramatic increases in consumption have raised public health concerns. Given the complexity of the topic spanning multiple academic disciplines and fields of professional practice, the need for a systematic overview is urgent.
  3. A good chew or good riddance

    The article reviews the status of khat, the most recent plant based psychoactive substance to reach a global market, and considers policy making processes in general and the framework of drug control in particular. The risk assessment and classification of psychoactive drugs is a contested arena where political, economic and moral agendas collide, leaving countries that have banned khat, with significant social costs. To best manage the risks arising from the increasing availability of khat it is therefore suggested to draft a regulatory framework with clear objectives and guiding principles.

    Regulating khat

    The regulation of khat, one of the most recent psychoactive drugs to become a globally traded commodity, remains hotly contested within different producer and consumer countries. As regimes vary, it has been possible to compare khat policies in Africa, Europe and North America from different disciplinary perspectives. The research established the significance of khat for rural producers, regional economies, as a tax base and source of foreign exchange. At the same time, khat as a psychoactive substance is associated with health and public safety problems that in turn are met with often ill-informed legislative responses. Bans have in turn lead to the criminalisation of users and sellers and illegal drug markets.
