We are aware that GHB (Gamma Hydroxybutyrate) is used recreationally at events, even though it’s not often brought to KnowYourStuffNZ for testing. It’s one of the substances that people think doesn’t need testing because it comes in an easily recognisable format. However, all of the samples brought to us as GHB this summer have turned out to be GBL (gamma-Butyrolactone).
GBL is chemically very similar to GHB and converts to GHB quickly once it enters the body. However it’s also two to three times stronger, making the amount required to overdose much lower. The amount that will cause an overdose is also bodyweight dependent, which means taking a GHB-sized dose of GBL can easily lead to overdose and death – especially for smaller people. Adding other drugs increases the risk. Alcohol is especially dangerous to combine with GHB or GBL.
It’s important to know whether you have GHB or GBL before ingesting – please test it first. If you done have access to KnowYourStuffNZ’s testing service, test kits can be purchased here. Avoid combining it with alcohol, other depressants, stimulants, or dissociatives. As ever, know what you are taking and research the risks.
