A grey area has emerged between what is legal and what is not as states struggle with how to respond to the many new synthetic compounds emerging onto the market. Of the various types of ‘Legal highs’ the seminar focused on stimulants because of the parallels with the other main drug-policy issue of the moment; i.e. the status of traditional herbal stimulants. These older discussions have been reinvigorated by: Bolivia’s efforts to de-schedule coca-leaf at UN level; the debates on the status of khat between EU States, and of kratom across Asia; and the increasing stride of legitimate cannabis use on the domestic front, as in for example Spain.
Khat leaves are cultivated in the highlands of the Horn of Africa, Southern Arabia and along the East African coast. In many countries, chewing khat is an age-old tradition. More recently, the mass migration of people from the Horn of Africa has been associated with the spread of khat usage to neighbouring countries, Europe and the rest of the world. Exact numbers of regular khat users on a worldwide scale do not exist, however estimates range up to 20 million. This paper presents the challenges associated with the spread of khat consumption.
