It is also a popular recreational drug called “liquid ecstasy” or “fantasy.” GBL is also an adulterant in illicit drugs such as ecstasy, methamphetamine, cocaine, and marijuana. Using GBL as an adulterant can be very dangerous, producing adverse reactions such as vomiting, nausea, agitation, and even coma. In New Zealand and Australia, GHB, 1,4-B, and GBL are all Class B illegal drugs, along with any possible esters, ethers, and aldehydes. GABA itself is also listed as an illegal drug in these jurisdictions, which seems unusual given its failure to cross the blood–brain barrier, but there was a perception among legislators that all known analogues should be covered as far as this was possible.
What Happens If You Have Too Much GHB/GBL/1,4-BD?
It is often sold or found in a variety of containers such as water bottles, eyedroppers and/or vitamin bottles. Ingestion is usually achieved by mixing the solution with a beverage, usually water or various alcoholic drinks. Like other drugs (e.g., ecstasy, marijuana) the chemical composition of GHB is highly variable, and sold in a wide range of concentrations. As a result, there is no definitive way for users to know how strong a particular form of GHB is, thereby increasing the risk of an overdose. Powder forms of GHB are not as prevalent as liquid forms, yet the method of use is nearly identical 13.

Treatment Options For GBL Dependence

These could include shakes, tremors, spasms, panic, hallucinations or delusions. While such dependency will not develop with infrequent users, anyone using GHB for a sustained period of time should seek expert drugs advice before discontinuing use abruptly 7. Like these other “club drugs,” GHB is taken because users feel that it enhances the experience of being in a club or at a party; small doses of GHB are thought to act as a stimulant and aphrodisiac. In clinical trials Xyrem significantly reduced cataplexy attacks at a dose of 6-9g per night, which is generally divided between two doses. This is about a third the dose used recreationally, but almost all narcolepsy patients in the clinical trials were already stabilized on CNS stimulants such as modafinil; in patients not prescribed modafinil, this dosage could be dangerous and should be reduced appropriately. Also, the prescribing information for Xyrem states that patients should take the dose immediately before going to bed, and then a second dose 3–4 hours later.
Alcohol (Ethanol) Interacts With GAMMA BUTYROLACTONE (GBL)
Because of this, it is unsafe to drive, operate machinery or do things that need concentration or motor coordination. These drugs can cause euphoria, increased sexual arousal, forgetfulness, slurred speech and risk taking, which can make interacting with others difficult. It may also mean you do or say things or act in ways that are out of character. GBL is used in various pharmaceuticals, agrochemicals, and industrial solvents. It is commonly used as a solvent for coatings, inks, adhesives, and resins.
How Do You Manage Withdrawal From GHB/GBL/1,4-BD?

GHB and GBL comedowns are generally not severe, and effects usually pass within a day. It is best not mix alcohol with GBL/GHB/1,4-BD as it increases unpleasant effects and your chance of overdose. Avoid mixing GHB, GBL or 1,4-BD with other depressant drugs, like alcohol. It is used in various industrial solvents, such as those found in paint thinners and cleaning products. It can also be used to produce certain pharmaceuticals and is used in some beauty products. Synthesizing gamma-butyrolactone (GBL), Cas # , is a complex process that involves several steps.
Other Types Of Depressants
In New Zealand and Australia, GHB, 1,4-B and GBL are all Class B illegal drugs, along with any possible esters, ethers and aldehydes. GABA itself is also listed as an illegal drug in these jurisdictions, which seems unusual given its failure to cross the blood-brain barrier, but there was a perception among legislators that all known analogues should be covered as far as this was possible. Another possibly fatal combination of substances are serotonergic substances, which might cause serotonin syndrome. Serotonin syndrome is a result of excess serotonin in the brain, which can cause seizures, anxiety, tremors, nausea, coma and possibly a deadly fever.
Giving up GHB after using it for a long time is challenging because the body has to get used to functioning without it. This is why it’s important to speak to a health professional when planning to stop using GHB. GHB and GBL produce essentially the same effects – feelings of euphoria, reduced inhibitions and drowsiness. The effects start after about 10 minutes to an hour and can last for up to seven hours or so 1. Orally, usually in small doses such as a teaspoon (5ml) at a time 6. Anecdotal evidence suggests that use of the drugs is fairly widespread on the UK club scene, particularly in gay clubs, but have yet to become significant players among the general drug-taking population 8.
Report Shows Concerning Signals In Overdose Trends
Different people will be more or less sensitive to the effects, just as with alcohol. If you buy or are given a pre-prepared solution of any of these drugs, the risks of accidentally taking too much is especially high. Taking an unmeasured dose of an unknown solution is very risky, even if it seems like a small amount. Measuring out doses millilitre by millilitre using a pipette, and starting with a small dose, reduces the risk 4. Taking GHB or GBL every day results in increased tolerance and users may become dependent on it. Those dependent on GHB and GBL usually suffer from cravings, anxiety, low mood, and have trouble sleeping if they do not re-dose every few hours 4.
Gamma-butyrolactone

Because of its strong sedative effects, patients should not drive or operate heavy machinery for at least six hours after taking sodium GHB. 1,4-Butanediol (also known as 1,4-B, BDO, BD or 1,4-BD) is a depressant substance and a prodrug for GHB. GBL and GHB have both been used medically as anesthetics and to treat conditions such as narcolepsy and alcohol withdrawal. GHB is also used to treat cataplexy, a condition characterized by sudden muscle weakness or paralysis. However, both substances have a high potential for abuse and are classified as controlled substances in many countries. Gamma-butyrolactone (GBL) and gamma-hydroxybutyrate (GHB) are two closely related chemicals that are often used for their euphoric and sedative effects.
GHB has been used in a medical setting as a general anaesthetic, to treat conditions such as insomnia, clinical depression, narcolepsy, and alcohol withdrawal, and to improve athletic performance 3. 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 it easy to overdose. Thank youHuge thanks to the volunteers who give their time freely to research and write this complex section. We are not doctors or substance misuse professionals, rather a group of gorgeous informed gay men, passionate about sex and our health, with direct experience of drug use, addiction, withdrawal, and recovery. Certain substances called “pro-drugs”, are changed to GHB in the stomach.
- You should be careful about accepting any form of drug (including alcohol) from someone who is not known to you.
- Unlike GHB, 1,4-Butanediol has a distinct taste, described as being repulsive, plastic-like and chemical.
- GHB and GBL testing windows can change depending on how much you have taken, how often and your individual body.
- GHB and GBL users can adopt a ’24/7′ dosing regime.39 This is where the user has become tolerant to the effects of the drug, increasing the dosage and frequency of dosage simply to avoid withdrawal symptoms.
- One study found that repeated administration of GHB to rats for 15 days drastically reduced the number of neurons and non-neuronal cells within the hippocampus and in the prefrontal cortex.
Gamma-butyrolactone (GBL) is used in cleaning solvents and similar industrial products. It is also used as a precursor to make the illicit substance gamma-aminobutyric acid (GHB) or is ingested to produce euphoric or sedative effects. GBL can cause many short-term and long-term risks and can lead to dependence and addiction.
Even at lower doses, GHB, GBL and 1,4-BD are drugs that can affect your day-to-day activities. The effects usually last up to 4 hours, after which you may start to experience a comedown period. The effects may last for a much longer period if you use GHB or GBL regularly, mix it with other drugs or take very large doses. In people who have used GHB or similar drugs regularly for a long time, ‘cold turkey’ withdrawal can sometimes be dangerous. It is important to speak with a medical professional first if you are worried about withdrawing from these drugs. Most people who use GHB, GBL or 1,4-BD will only use them from time to time and are unlikely to develop addiction or dependence to the drug.
You can become addicted to GHB and GBL and experience unpleasant effects when you stop taking it. Overall, the long-term effects of GHB, GBL and 1,4-BD have not been well researched, so it can be hard to predict what might happen if you use this drug regularly for a long time. GHB, GBL and 1,4-BD can be very easy to overdose on because there is a small difference between a common dose and a dangerous dose. Drugs affect everybody differently, depending on things like your body size, any other drugs you’ve taken, what you have eaten, where you are, and how you’re feeling. GBL has a low oral LD50, the amount of a substance that must be consumed to cause death in 50% of the test population.

Before we get into the specifics of how to store GBL properly, let’s first review some basic safety information. GBL is a colorless, odorless, highly flammable liquid that can be hazardous to human health. It’s essential to keep GBL away from any open flames or other heat sources and always to wear protective clothing, such as safety glasses, gloves, and a respirator when handling it.
The sedative properties of GHB and its related compounds, as well as their neutral odour and taste have led some to link the drugs to instances of drug-facilitated sexual assault, although the extent of the drugs’ use in these crimes remains unclear. A 2006 study by the Association of Chief Police Officers (ACPO) found that of 120 instances of alleged drug-facilitated sexual assault, only two victims had tested positive for GHB. GHB, GBL and 1,4-BD are clear, odourless, oily liquids that taste slightly salty. When intended for illicit use, GHB, GBL and 1,4-BD are sold in small bottles or capsules.
