Schwag

American slang for low-quality, often Mexican brick cannabis, attested from the 1990s — earliest documented use c. 1995 in U.S. campus slang. Dictionary.com dates it 1990–1995 as an alteration of swag (19th-century thieves' cant for "plunder" or "cheap goods"). ⚠️ Etymology disputed: some trace influence to Yiddish shvakh ("weak"), paralleling Yiddish-style sch- prefixing (schlock, schmuck); others treat it as a phonetic variant of swag. Wordnik and the OED favor the swag derivation. Has largely faded in legal-market states.
