All of the above indicates that the programme for eradication of khat and its consumption following the prohibition law of 1983 has been successful. At present, the problem of khat-chewing affects seriously only some of the countries in the Arabian Peninsula and East Africa. In the latter area, neighbouring countries are affected, but the degree of severity of the khat problem varies considerably among them. As the khat-chewing habit has for centuries been limited to the same geographical area where it has been traditionally grown and habitually consumed, it may also be assumed that the problem will always remain within its traditional boundaries. However, in a world where rapid changes are taking place in the way of thinking and of life, this assumption may prove to be dangerously wrong.
Modern communications make the importation of new habits and fashions very easy.
This transformation occurred without arousing much alarm until it was almost too late. Furthermore, it has been observed that some foreign experts and visitors fall victim to khat-chewing during their stay in areas of endemic use. On their return home, these new disciples of khat may be tempted to continue in the newly acquired habit, favoured in this by the availability of fresh khat transported by air. It would not be a hard task for them to spread the habit to other eager followers. At present, khat consignments reach some European countries where the drug is consumed mainly by immigrants from areas of endemic use.
