Chewing over Khat prohibition
The globalisation of control and regulation of an ancient stimulant
Khat has been consumed for thousands of years in the highlands of Eastern Africa and Southern Arabia.Strict bans on khat introduced in Europe ostensibly for the protection of immigrant communities have had severe unintended negative consequences.
Discussions about appropriate regulatory systems and the implications of rising khat use for European drug policies should take cognizance of social, demographic and cultural trends, and compare the existing models of control that exist in Europe. Khat provides a unique example of a herbal stimulant that is defined as an ordinary vegetable in some countries and a controlled drug in others. It provides a rare opportunity to study the effectiveness, costs and benefits of diverse control regimes. As long as khat is legally produced and traded, it also allows for the views of stakeholders such as farmers and traders to be included in policy discussions.
Conclusions & recommendations
- Where khat has been studied extensively, namely Australia, the UK and until recently the Netherlands, governments have steered clear of prohibition because the negative medical and social harms do not merit such controls.
- Strict bans on khat introduced ostensibly for the protection of immigrant communities have had severe unintended negative consequences.
- Khat prohibition has failed to further the integration, social incusion and economic prosperity of the Somali community.
- Assumptions about causal relations between khat use and the problems of a vulnerable minority with untreated mental health conditions need to be dealt with carefully and should not be used as a pretext for criminalising khat.
- Migrant communities and problematic users need a constructive engagement and targeted interventions. The criminalisation of a cultural practice will only intensify the problem that community leaders are seeking to address.

Martin Jelsma
Martin Jelsma is a political scientist who has specialised in Latin America and international drugs policy. In 2005, he received the Alfred R. Lindesmith Award for Achievement in the Field of Scholarship, which stated that Jelsma "is increasingly recognized as one of, if not the, outstanding strategists in terms of how international institutions deal with drugs and drug policy."
In 1995 he initiated and has since co-oordinated TNI's Drugs & Democracy Programme which focuses on drugs and conflict studies with a focus on the Andean/Amazon region, Burma/Myanmar and Afghanistan, and on the analysis and dialogues around international drug policy making processes (with a special focus on the UN drug control system). Martin is a regular speaker at international policy conferences and advises various NGOs and government officials on developments in the drugs field. He is co-editor of the TNI Drugs & Conflict debate papers and the Drug Policy Briefing series.
