GHB & GBL

How long the effects last and the drug stays in your system depends on how much you’ve taken, your size and what other drugs you may have also taken.

To kick in

It can take from 10 minutes to an hour for GHB or GBL to take effect. You should always wait for at least two hours before taking another dose. Overdosing on GHB and GBL is very easy to do.

The effects can last for seveal hours.

How long a drug can be detected for depends on how much is taken and which testing kit is used. This is only a general guide.

GHB (gammahydroxybutrate) and GBL (gammabutyrolactone) look identical.

They are sold as:

• colourless oily liquids
• capsules, but this is rare
• as powder or paste, but this is also rare

GHB has a medical use in the treatment of narcolepsy, and GBL is used in stain remover, rust remover, superglue remover, as an alloy cleaner and as a paint stripper.

• GHB has almost no smell and a salty/soapy taste.
• GBL has a very strong chemical taste and smell.

It's very easy to overdose on GHB and GBL. This is because there's only a very small difference between the dose causing the desired effects and the dose leading to severe overdose.

Experienced users measure the drug out very carefully using a pipette or a syringe, or by filling pre-measured vials (small bottles) to avoid taking too much. If you don’t measure the dosage, you’re likely to overdose and fall unconscious.

Orally

Drinking GHB or GBL on its own would lead to chemical burns in your mouth and throat. Because of this, people take GHB and GBL orally by using a pipette, syringe or pre-measured vial to measure the dose and then mix it into a soft drink.

Injecting

You can’t inject GBL, but some people inject GHB – although this is rare and particularly dangerous.

Snorting

You can’t snort GBL (as it’s a liquid), but some people snort GHB powder, but this is also very rare.

Yes, people who take GHB or GBL regularly can develop a dependence on the drug. People have reported the following withdrawal symptoms: confusion, shaking, epileptic seizure and coma.

These withdrawal symptoms are especially likely if the user runs out of the drug and has to suddenly stop taking it.

Like drink-driving, driving when high is dangerous and illegal. If you’re caught driving under the influence, you may receive a heavy fine, driving ban, or prison sentence.

If the police catch people supplying illegal drugs in a home, club, bar or hostel, they can potentially prosecute the landlord, club owner or any other person concerned in the management of the premises.

GBL is available for legitimate use in industry, but if someone supplies or possesses it knowing or believing that it will be swallowed and ingested, they are committing an offence.

The Sexual Offences Act 2003 states that it is an offence to administer a substance, like GHB and GBL, to a person with intent to overpower that person to enable sexual activity with them. This is punishable by up to 10 years imprisonment.
