Amphetamine sulphate is a white or off-white powder that is soluble in water. Illicit products mostly consist of powders, usually mixed with other ingredients, such as lactose, dextrose or caffeine, but tablets containing amphetamine are also available and may carry logos similar to those seen on ‘ecstasy’ tablets. Captagon tablets containing amphetamine are produced and consumed in large numbers in south-eastern Europe. Amphetamine sulphate may be ingested, snorted and, less commonly, injected. Unlike the hydrochloride salt of methamphetamine, amphetamine sulphate is insufficiently volatile to be smoked.
