English edit

Etymology edit

From methamphetamine, apparently by analogy with amphetamines.

Noun edit

methamphetamines pl (plural only)

  1. Methamphetamine.

Usage notes edit

  • Since the term methamphetamine denotes a specific compound (one of the amphetamines), the term methamphetamines may be considered meaningless; nonetheless, it is in wide use as a synonym for methamphetamine, though less so in technical literature.
