Iran is a key transshipment point for Southwest Asian heroin to Europe.

It has also become a key transshipment point for Asian heroin and Latin American cocaine.

Southeast or Southwest Asian heroin both are available to varying degrees in markets throughout the country.

Southwest Asian heroin averaged 29.8 percent in six cities.

The purity of Southeast Asian heroin was 23.9 percent in four metropolitan areas.

Chinese and West African criminal groups control the wholesale distribution of Southeast Asian heroin.

The rumored wholesale price for two tons of Asian heroin was forty million dollars, cash.

It is also at this stage that another complication arises for Southeast Asian heroin.

The light-brown crystals found in the straining cotton in the kit came back as 55 percent pure heroin, Asian blend.

More recently, with some assistance from the Triads, they've begun to deal in Asian heroin, as well.
