"molly" is slang related to drug use: slang for mdma, especially in pure crystalline or capsule form. If your teen uses it casually, it does not automatically mean they are using; many young people repeat drug slang they see in song lyrics, memes, or films without first-hand experience. However, repeated, context-specific use (talking about scoring, prices, plans for the weekend) is worth a calm, non-confrontational conversation. Ask open questions rather than reacting to the word itself, and check what they actually know about the substance.

Definitions
Slang for MDMA, especially in pure crystalline or capsule form. Distinct from "ecstasy," which traditionally refers to pressed pills that may be cut with other substances. The street supply is rarely actually pure MDMA — testing kits are widely advised.

"molly" is informal English meaning slang for mdma, especially in pure crystalline or capsule form. It is used widely across English varieties. A more formal or neutral equivalent would be something like "slang for mdma" expressed in standard vocabulary. A common mistake is to assume "molly" can replace its standard equivalent in every register; keep it for spoken or casual situations and use the formal form in writing. If you are a B2 or C1 learner, it is useful to recognise this word when you hear or read it, but think carefully about whether the situation really calls for it before using it yourself.

Why is this section here?
Slang is read by different audiences for very different reasons. The For parents view re-explains the term in plain, non-judgemental language so a caregiver can understand what their child means without needing the surrounding subculture. The For English learners view focuses on register (when it's safe to use), formal alternatives, and common mistakes — what a textbook won't teach you.
