Gamma-Butyrolactone Overdose Potentially Complicated by Co-Ingestion of Industrial Solvent N-Methyl-2-Pyrrolidone

J Anal Toxicol. 2021 Mar 12;45(3):322-324. doi: 10.1093/jat/bkaa076.

Abstract

Gamma-hydroxybutyrate (GHB) is misused as an intoxicant, either alone or concurrently with other substances. Because GHB is illegal, the precursor chemicals 1,4-butanediol and gamma-butyrolactone are also misused for the same effect, either through pre-ingestion alteration or endogenous metabolism to GHB. We describe a case of a 50-year-old man with a history of polysubstance misuse who experienced an overdose of GHB from gamma-butyrolactone ingestion. The patient also co-ingested a common industrial solvent, N-methyl-2-pyrrolidone (NMP). This co-ingested substance raised theoretical concern of metabolism to a GHB congener, underscoring that the emergence of new psychoactive substance use patterns requires ongoing vigilance and toxicologic confirmation.
