Hub of illicit drug trade: Criminal networks in Africa are setting up fake pharmaceutical companies as a front to trade in substances used to make street methamphetamines, a psychostimulant, the International Narcotics Control Board's 2008 annual report said. Companies forge import permits to illegally divert ephedrine and pseudoephedrine, ingredients in the highly addictive central nervous system stimulant crystal meth, the report added. Inadequate laws and ineffective administrative mechanisms have led to poor enforcement of controls like licensing and inspection of distribution channels of these drugs.
