Gamma butyrolactone (GBL) is also known by other chemical names, including dihydro-2(3H)-furanone, 4-butanolide, 2(3H)-furanone dihydro, tetrahydro-2-furanone, and butyrolactone gamma. When GBL enters the body, it is broken down to gamma hydroxybutyric acid (GHB), an equally dangerous chemical that is also sold illegally. Because the body absorbs GBL better than it does GHB, any given amount of GBL is more potent than the same amount of GHB. Dietary supplements, which are now illegal because they contain GBL, GHB, or the related chemical 1,4 butanediol (BD), could list these ingredients on the label, or they might list tetramethylene glycol or 2(3H)-furanone dihydro. However, some of these products have no label at all. Now that GBL is illegal, it is sometimes made in secret laboratories. As a result, the purity, potency, and contaminants of the drug are completely unpredictable, adding to the dangers involved in using it.
