An analogue that is not a 1,4-butanediol derivative but is related and still shows affinity for the GHB receptor is 3-chloropropanoic acid (UMB66). The risk of having your drink spiked with GHB should not be exaggerated. American research has shown that alcohol alone is implicated in over 90% of sexual assaults. The listed effects will rarely (if ever) occur all at once, but heavier doses will increase the chances and are more likely to induce a full range of effects.
How Can You Be Safer When Using GHB/GBL/1,4-BD?
It is possible for oral ingestion of GBL to cause nausea and other similar problems, possibly more so than with GHB. GHB (Xyrem) was approved by the FDA in 2002 for use in the treatment of narcolepsy/Cataplexy 3. Synthesis of this chemical was first reported in 1874 by Alexander Zaytsev. But the first major research in humans was conducted in the early 1960’s by Dr. Henri Laborit to use in studying the neurotransmitter GABA.
Identify Raw Materials Immediately – Without Waiting Time

Using GHB in combination with alcohol is dangerous even in small amounts. If you choose to use GHB avoid mixing it with other alcohol and other drugs. Methamphetamine suppresses autonomic response and can cause sores and abrasions in the mouth. Another study found no effect following intracerebroventricular injection of butane-1,4-diol in rats.21 This contradicts the hypothesis of butane-1,4-diol having inherent alcohol-like pharmacological effects. Otherwise, effects are similar to GHB, although weight for weight it is significantly more powerful, meaning dosage must be lowered accordingly. If ingested undiluted through the oral route, GBL can irritate innards.
If you don’t measure the dosage, you’re likely to overdose and fall unconscious. This explains the paradoxical mix of sedative and stimulatory properties of GHB,115 as well as the so-called “rebound” effect, experienced by individuals using GHB as a sleeping agent, wherein they awake suddenly after several hours of GHB-induced deep sleep. Because of the faster and more complete absorption of GBL relative to GHB, its dose-response curve is steeper, and overdoses of GBL tend to be more dangerous and problematic than overdoses involving only GHB or 1,4-B. Any GHB/GBL overdose is a medical emergency and should be cared for by appropriately trained personnel. Evidence is emerging that shows it is possible to become physically dependent on GHB and GBL/1,4-BD.

Therefore, it is best to keep GBL away from areas where children and pets can access it. Finding reliable suppliers can be difficult, but there are a variety of ways to locate suppliers. Anbu Chem is one gamma-butyrolactone supplier in China known for providing quality GBL at competitive prices. Furthermore, Anbu Chem offers a variety of shipping options, meaning you can select the best method for you.

The drugs do not feature in any of the major national surveys of recreational drug use, such as the British Crime Survey Drug Misuse Declared bulletin. GHB (Gamma hydroxybutyrate) is an anaesthetic with primarily sedating rather than painkilling properties. It is often sold as ‘liquid ecstasy’ because of its relaxant and euphoric effects, although it has no relationship to ecstasy.
- People who are dependent on or addicted to GBL may benefit from professional advice and treatment.
- It is also recommended to store your GBL in a container that no one would drink out of.
- When taken in large doses, GBL can cause various side effects, including dizziness, drowsiness, confusion, difficulty breathing, vomiting, agitation, and in severe cases, coma and even death.
- Friends should always look out for each other – if someone is suffering bad effects, then seek medical assistance immediately.
- In so far as gay men are more likely to have heard about ‘safer sex’ and ‘safer drug use’, ‘harm…

Additionally, if you have a history of addiction or mental illness, seeking treatment before using GBL is essential. This is because there’s only a very small difference between the dose causing the desired effects and the dose leading to severe overdose. 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. Mixing GHB/GBL with other drugs can have unpredictable effects and increase the risk of harm.

What Is Gamma-butyrolactone Used For?
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. GHB can be easiliy manufactured from GBL which is typically sold in plastic bottles, sometimes labelled but often unmarked 5.
In Hong Kong, GHB is regulated under Schedule 1 of Hong Kong’s Chapter 134 Dangerous Drugs Ordinance. It can only be used legally by health professionals and for university research purposes. Anyone who supplies the substance without prescription can be fined HK$10000.

Further, never mix GBL with alcohol or other drugs, as this could lead to serious health complications. Other side effects of GBL include nausea, headache, blurred vision, rapid heart rate, and increased blood pressure. In addition, long-term abuse of GBL can lead to severe psychological and physical problems. This can include depression, anxiety, paranoia, and even psychotic episodes. It is formed from the condensation of 1,4-butanediol with acetaldehyde.
It can also be a good idea to colour liquid GHB/GBL/1,4-BD with blue food colouring. This way, it will not be mistaken for water and added to your or someone else’s drink without knowing. Be aware that other methods of using GHB, GBL and 1,4-BD (snorting/injecting) can increase your risk of overdose. Snorting or injecting GHB, GBL or 1,4-BD will deliver these drugs to your body much quicker, which can increase your chances of overdosing. If you do chose to snort or inject these drugs, use new and sterile utensils and equipment every time. GBL is often adulterated with other substances, such as ketamine, GHB, and caffeine.
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. This means GBL is relatively safe to use and handle compared to other industrial solvents. It is used as a sedative and hypnotic, as an anesthetic, and as an antidepressant.

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. As a supplement/drug, it is used most commonly in the form of a salt.7 GHB is also produced as a result of fermentation, and so is found in small quantities in some beers and wines. Succinic semialdehyde dehydrogenase deficiency is a disease that causes GHB to accumulate in the blood. GBL is not considered to be as safe as GHB used responsibly or medicinally, since it is theorized to display additional toxic effects on the body, unlike GHB. The LD50 is above the active dosage, and there is no danger of acute toxicity.
With doses of 10 mg/kg of GHB, they were decreased by 61% in the CA1 region and 32% in the prefrontal cortex, and with 100 mg/kg, they were decreased by 38% and 9%, respectively. It is interesting to note that GHB has biphasic effects on neuronal loss, with lower doses (10 mg/kg) producing the most neurotoxicity, and higher doses (100 mg/kg) producing less. 1,4-Butanediol is not active in its own right; its mechanism of action stems from its identity as a prodrug of GHB, meaning that it is rapidly converted into GHB in the body. 1,4-Butanediol is classified as a subclass of alcoholic compounds called diols.
Auditory Effects
There is a particularly high chance of accidental overdose with GHB and GBL, because an extra half-millilitre of GBL or half-gram of GHB on top of a moderate dose can make you fall into a deep sleep where you could potentially choke to death on your own vomit. Knowledge of the recovery position and how to clear an airway could save lives. Slightly higher quantities can cause coma-like unconsciousness from which the user cannot be woken. This respiratory depression can easily kill or cause brain damage, (although most people who overdose will recover without lasting consequences). Large overdoses can also cause seizures, and interfere with or stop the heartbeat.
