Methamphetamine is a more potent form of the drug amphetamine. Both amphetamine and methamphetamine belong to the ‘stimulant’ class of drugs, which also includes ecstasy and cocaine. These drugs stimulate the brain and central nervous system.

Methamphetamine comes in different forms, including powder/pills (“speed”), a sticky paste (“base”), or a crystal form (“ice”). Powder is the least potent form, while crystal is the most potent. Methamphetamine may be swallowed, injected, smoked or snorted. Occasionally people ‘shaft’ it (suppository).
