Prolong use of GHB can result in the user developing a tolerance, requiring larger doses to achieve the desired effects. As doses and frequency of its use increases the user is at great risk of developing an physical and psychological dependency to the drug. When stopping the use of GHB abruptly the user will experience withdrawal symptoms that can be painful and overwhelming 18. The levels of lactonase enzyme can vary between individuals, meaning that first-time users can show unpredictable results, even from small doses. In many this manifests as slow onset of effects, followed by headaches, semi-consciousness which is distinct from GBL sleep in normal users.
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. It is rapidly converted into GHB by lactonase enzymes found in the blood. A 2022 review22 compared 43 studies on GHB-induced cognitive impairment in humans and animals. The analysis suggests that moderate or clinical use may result in acute cognitive impairment.
Sought After Effects
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. Additionally, if abruptly stopped, GBL can cause physical dependency and addiction and lead to withdrawal symptoms. Furthermore, GBL has been known to interact with other legal and illegal drugs and can cause serious health issues when taken with certain medications. GHB and GBL are depressant drugs which can produce a mild high in smaller doses and sedation in higher doses. Users of GHB/GBL and 1,4-BD report that the drugs make them feel euphoric, with a loss of inhibitions, increased confidence and higher libido.
As GHB/GBL and 1,4-BD help promote ‘slow wave sleep’, during which growth hormone is secreted, the substances have also been used by bodybuilders. 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. As a lactone, GBL is hydrolyzed under basic conditions, for example in a sodium hydroxide solution into sodium gamma-hydroxybutyrate, the sodium salt of gamma-hydroxybutyric acid. In acidic water, a mixture of the lactone and acid forms exists in an equilibrium. These compounds then may go on to form the polymer poly(4-hydroxybutyrate) as well as the dimer 1,6-Dioxecane-2,7-dione. When treated with a non-nucleophilic base, such as lithium diisopropylamide, GBL undergoes deprotonation of the alpha carbon atom to the carbonyl.
GHB was synthesised and introduced into medicine in 1960 and in 1963 discovered as a naturally occurring chemical in the human brain 22. Throughout much of the 1960’s it was a popular anaesthetic, but was abandoned by doctors following discoveries of its poor analgesic effects 23. In the 1970’s, GHB was recommended for the treatment of narcolepsy, though it was also found to be an ineffective and unpopular form of treatment primarily due to its euphoric side-effects. Use began to intensify in the 1980’s when it was marketed as a fat burner and muscle developer.
GBL / GHB
GHB overdose is a medical emergency and immediate assessment in an emergency department is needed. Gamma hydroxybutyrate (GHB) and Gamma-Butyrolactone (GBL) are depressant drugs with strong sedative effects. GHB and GBL look, taste, and smell the same, but GBL is stronger as it is converted into GHB in the body. GHB was developed in the USA as a pre-medication to help patients sleep before surgery. Some people who use the drug illicitly do so not for the euphoric effects, but rather use higher doses to help them sleep.
Where To Buy Gamma Butyrolactone (GBL)?
This is especially important for 1,4-BD as it might take longer to feel the effects than if you were taking GHB or GBL. If you plan on re-dosing, consider separating out your doses into small containers and use a phone alarm to schedule when you’ll take them. Reduce the amount you’re re-dosing with each time to lower your risk of overdose.
GHB: Swallowed
GHB is produced in the body in very small amounts, and blood levels may climb after death to levels in the range of 30–50 mg/L.57 Levels higher than this are found in GHB deaths. Levels lower than this may be due to GHB or to postmortem endogenous elevations. Also note that both of the metabolic breakdown pathways shown for GHB can run in either direction, depending on the concentrations of the substances involved, so the body can make its own GHB either from GABA or from succinic semialdehyde. Under normal physiological conditions, the concentration of GHB in the body is rather low, and the pathways would run in the reverse direction to what is shown here to produce endogenous GHB. However, when GHB is consumed for recreational or health promotion purposes, its concentration in the body is much higher than normal, which changes the enzyme kinetics so that these pathways operate to metabolise GHB rather than producing it.
Pharmacology Of GHB
The sodium salt of GHB has a salty taste.34 Other salt forms such as calcium GHB and magnesium GHB have also been reported, but the sodium salt is by far the most common. GHB induces the accumulation of either a derivative of tryptophan or tryptophan itself in the extracellular space, possibly by increasing tryptophan transport across the blood-brain barrier. The blood content of certain neutral amino-acids, including tryptophan, is also increased by peripheral GHB administration. GHB-induced stimulation of tissue serotonin turnover may be due to an increase in tryptophan transport to the brain and in its uptake by serotonergic cells.
- GBL is currently found in a number of products including stain and glue removers, and industrial solvents.
- The information below is from other websites about how much people commonly use overseas.
- GBL 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.
- People using up to 30mls per day – or more – face an increased risk of severe withdrawal symptoms that might need specialist treatment.
- While butane-1,4-diol is not currently scheduled federally in the United States,22 a number of states have classified 1,4-butanediol as a controlled substance.
Lying in the recovery position can prevent one from suffocating on their own vomit. Avoid mixing GHB/GBL/1,4-BD with other drugs, especially alcohol and depressants. GHB and GBL have very strong effects, and when mixed with other drugs, they can become more dangerous. This is especially the case for alcohol and other depressant drugs as effects become more intense and the risk of overdose increases. GHB, GBL and 1,4-BD are most commonly mixed into a drink and swallowed, which releases them into your body slower than by snorting or injecting. If you swallow GHB, GBL or 1,4-BD, try to wait for 2 hours before re-dosing as you may not feel the effects right away.
More Drugs
- This means someone who takes a second dose without having waited for the effects to reach their peak could be taking a big risk.
- 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.
- Test your GHB, GBL and 1,4-BD to make sure it isn’t mixed with other drugs.
- Use began to intensify in the 1980’s when it was marketed as a fat burner and muscle developer.
- It is often sold or found in a variety of containers such as water bottles, eyedroppers and/or vitamin bottles.
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. These contaminants can cause serious health problems, including organ failure and death.
Safety Tips For Using GHB:
The penalty for trafficking or manufacturing the substance is a HK$150,000 fine and life imprisonment. Possession of the substance for consumption without license from the Department of Health is illegal with a HK$100,000 fine or five years of jail time. GBL (Gamma butyrolactone) and 1,4-BD (1,4-butanediol) are chemicals that are closely related to GHB. Once GBL or 1,4-BD enter the body, they convert to GHB very quickly. To avoid a possible overdose of GBL, it is important to start with a low dose and work your way up slowly by increasing the dosage in small increments. One should best use a glass bottle with an integraded 1ml pipette to exactly measure their dosages.
Dangerous Combinations
In the United States, GHB is classified as a Schedule I controlled substance, meaning that it is illegal to manufacture, distribute, or possess without a license. GBL is not specifically listed as a controlled substance in the US, but it is considered a precursor chemical to GHB and is therefore regulated. In other countries, both substances may be classified as controlled substances.
In the 1980’s It was marketed for a short time as a fat burner and muscle developer. However, in 1990, based off many reports of GHB-linked illness, the FDA declared GHB unsafe, and ordered it to be removed from stores shelves. These drugs may be carried in quantities enough for several overdoses, so it may be safest to prepare in advance the quantity you wish to take in one session so that when intoxicated, you can only take up to an arranged limit. GBL is converted to GHB in the body, appears in the same liquid form and produces equivalent effects to GHB 5.
One leading fine chemical supplier in China, we can supply you with different raw materials of pharmaceutical intermediates and custom synthetic services. GBL is a highly toxic chemical and can cause serious health problems if ingested. 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.
Anxiolytic effects are diminished and side effects increased when used in combination with alcohol. Gamma-butyrolactone is rapidly converted into GHB by lactamase enzymes found in the blood. GBL is more lipophilic (fat soluble) than GHB, and so is absorbed faster and has higher bioavailability; the paradox is that this can mean that GBL has a faster onset of effects than GHB itself, even though it is a prodrug.
