Gamma-Butyrolactone (also known as γ-butyrolactone and commonly as GBL) is a synthetic depressant substance of the tetrahydrofuran chemical class that produces powerful euphoric and disinhibiting effects similar to that of alcohol intoxication. In humans it acts as a prodrug for GHB, where 1ml is equivalent to 1.66 grams of GHB.
