GHB

KO drops

GHB (gamma-hydroxybutrate) is an anaesthetic often referred to as 'KO Drëpsen' (KO drops) in Luxembourg.  

GBL (gamma-butyrolactone) is a very similar substance that is converted into GHB when consumed and produces identical effects.

Forms

GHB is generally sold in liquid form or in the form of a white powder dissolved in liquid, such as water, juice or alcohol. In liquid form, GHB is clear, colourless and slightly salty in taste. GHB is used for medical purposes in the treatment of narcolepsy.

GBL is used in the automotive industry as a stain remover, rust inhibitor, superglue remover, alloy cleaner and paint stripper. It therefore has a very strong chemical taste and smell.

Effects

The effects begin to be felt around 10 to 30 minutes after ingestion. They can last for several hours.

The duration of the effects depends on the quantity consumed, the person's weight and age, and if they have taken any other medication or substances.

GHB and GBL produce similar effects, which can be comparable to the effect of drinking alcohol.

At low doses, they can make a person: euphoric, relaxed and excited, also with disinhibitory effects.

If GHB or GBL are consumed in high doses, the effects include loss of consciousness and the risk of dizziness and light-headedness.

Risks

In liquid form, GHB can be added to a drink (in a nightclub, for example) without being noticed, which makes it very dangerous. In addition to its sedative effects, which can prevent victims from resisting sexual assault, this drug can also cause amnesia. When the effects wear off, the victims no longer remember what happened to them.

GHB and GBL can also be addictive when used regularly, and it is easy to consume too much of the substance and overdose as a result.

Dangerous combinations

It is dangerous to combine GHB with other drugs – particularly other depressants and sedatives. The effects of these different substances are cumulative and amplify each other. These combinations pose a serious risk to health.
