The latter development is evidenced by the fact that East African countries and certain European countries have reported annual growth in seizures of heroin of African origin. This may be a reason for the increased abuse of heroin in East Africa. Traffickers in search of new illicit markets for cocaine and heroin have targeted the nascent middle class in certain African countries, such as Benin, which has been used as a transit country for many decades, and Namibia, a transit country that is becoming a consumer country.
