GHB (gammahydroxybutrate) and GBL (gammabutyrolactone), are closely related, dangerous drugs with similar sedative and anaesthetic effects.
GBL is converted to GHB shortly after entering the body. Both produce a feeling of euphoria and can reduce inhibitions and cause sleepiness.
But both can kill and are particularly dangerous when used with alcohol and other depressant or sedative substances.

Appearance
When they are sold as drugs they are usually sold as an odourless, colourless, oily liquid in small bottles or capsules and they both taste slightly salty. A teaspoon or a capful is a normal dose although the strength of GHB varies so it can be very difficult for people to know how much they're taking, making easy to overdose.
There is a form of GHB (called iGHB) that does come in powder form but is rare. Prices can vary from region to region, on average a 30ml plastic container of GHB costs about £15.

Use
GHB has a medical use in the treatment of narcolepsy, while GBL has a legitimate use as a stain remover, rust remover, alloy cleaner, superglue remover and as a paint stripper.

GHB and GBL and the law
GHB and GBL are both Class C drugs - but GBL is available for legitimate use in industry, but if someone supplies or possesses them knowing or believing that they will be swallowed and ingested, they are committing an offence.
Possession can get you up to two years in prison and/or an unlimited fine.
Supplying someone else, even your friends, can get you 14 years in jail and/or an unlimited fine
Did you know?
A conviction for a drug-related offence could have a serious impact. It can stop you visiting certain countries – for example the United States – and limit the types of jobs you can apply for.
Like drinking and driving, driving while impaired from using GHB and/or GBL is illegal – you can get a heavy fine, be disqualified from driving or even go to prison.
Allowing other people to use GHB and/or GBL in your house or any other premises is illegal. If the police catch someone using GHB and/or GBL in a club they can prosecute the landlord, club owner or person holding the party.
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.
This depends on which drug you are talking about and what method is being used to test for the drug. The list below shows the drug detection times (using a urine test) for the most common drugs:
By mixing drugs you increase the chances of having a bad time. The effects of the drugs might be greatly increased, the drugs might interact in an unexpected way or one drug may stop part of your body working properly which makes the other drug(s) that have been taken more dangerous.
All drugs are potentially dangerous and have varying effects on individuals, so it is not possible to name the worst drug. For more information on the effects and risks of various drugs go to the A-Z of drugs.
