The term "methamphetamines" is often used broadly to represent the amphetamine derivates: methamphetamine, the designer drug MDMA (ecstasy), and other designer drugs. These substances are similar in chemistry and also have generally similar effects on users. In addition, MDMA is known to show significant cross-reactivity with many types of methamphetamine urine screen tests. Prescription and illicit forms of methamphetamine are discussed below. The designer drug MDMA is discussed on a separate page.
