Gamma-Butyrolactone is a hygroscopic colorless oily liquid with a weak
characteristic odor and is soluble in water.
GBL is a common solvent and reagent in chemistry and is used as an aroma
compound, as a stain remover, as a superglue remover, as a paint
stripper, and as a solvent in some wet aluminium electrolytic
capacitors.GBL has been found in extracts from samples of unadulterated
This finding indicates that GBL is a naturally occurring component in
some wines and may be present in similar products.
The concentration detected was approximately 5 μg/mL and was easily
observed using a simple extraction technique followed by GC/MS analysis.
Effects: Journalists have long been calling GHB liquid ecstasy. This is
incorrect - the effects are similar, but different: warm fuzzy feeling,
chattiness, increased energy, ability to stay awake longer, overwhelming
horniness, emotional intensity.
It is not for nothing that GBL took off in the sx clubs and spread to
more mainstream users from there. It's been described as 'a lovely
mellow buzz that leaves you functional and normal, but completely at
ease with the world'.
