GBL is a synthetic depressant of the lactone chemical class that functions as a prodrug for GHB, producing powerful euphoric and disinhibiting effects comparable to alcohol intoxication. It is widely available as an industrial solvent and cleaning agent. GBL is a strong acid that corrodes mucous membranes and must be heavily diluted in a non-alcoholic beverage before oral consumption. It also dissolves most plastics, requiring glass or high-density polyethylene containers for storage.
