Powder methamphetamine

Powder methamphetamine -- also known as speed -- is not common in Southeast Asia, although it has been found in Cambodia, Indonesia, Japan, and Thailand. However, it is the most popular form of methamphetamine in Australia and the United States. Powder ranges in color from dingy white to reddish brown, depending on the chemicals used in the manufacturing process. It is usually injected or snorted; it can also be orally ingested or smoked. Due to lack of capacity to perform chemical analyses among many of the countries in the region, there is some concern that seizures of powder methamphetamine may sometimes be misidentified as heroin.
