FDA warns about products containing gamma butyrolactone or GBL and asks companies to issue a recall. GBL presents cross-tolerance with 1,4-Butanediol and GHB, since GBL and 1,4-Butanediol act as prodrugs for GHB. Cross-tolerance with other depressants such as alcohol, phenibut, baclofen and other GABAB-agonists is likely. 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. GBL (gamma-butyrolactone) is a cyclic ester of gamma-hydroxybutanoic acid.
The ADF acknowledges the Traditional Custodians of the lands across Australia upon which we work. We recognise the continued connection of First Nations people to the land, the waterways and to community and kin, and pay respects to Elders past and present. At present, there is little reliable evidence to determine the purity of GBL. GHB and GBL will typically show up in a urine sample for 24 hours afterwards.

Its chemical structure is similar to that of ketone body beta-hydroxybutyrate. As a supplement or drug, it is used most as a salt.6 GHB is also produced as a result of fermentation. Small amounts of the substance can be found in some beers and wines. 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.
Unlike GHB, 1,4-Butanediol has a distinct taste, described as being repulsive, plastic-like and chemical. To check the type of plastic used on a bottle, one can look at the bottom for a number in the triangle-shaped recycling label. 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. Keeping the lid tightly sealed is also essential to ensure the GBL doesn’t evaporate. GBL is also highly soluble in water, so it should be kept from any excess moisture in the air. It’s best to keep GBL in its original container, as plastic containers may leach chemicals into the GBL, making it less effective.
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. GBL is also used to treat narcolepsy and enuresis and to reduce muscular spasms.
Aké Sú Účinky GHB?
It is found naturally as a neurotransmitter and is also a precursor to GABA, glutamate, and glycine in certain brain areas. It acts on the GHB receptor and is a weak agonist at the GABAB receptor. Mixing GHB/GBL with other drugs can have unpredictable effects and increase the risk of harm. These withdrawal symptoms are especially likely if the user runs out of the drug and has to suddenly stop taking it.
How Do You Manage Withdrawal From GHB/GBL/1,4-BD?
That is to say that, over time, the concentration of GHB in the system decreases below the threshold for significant GABAB receptor activation and activates predominantly the GHB receptor, leading to wakefulness. Evidence is emerging that shows it is possible to become physically dependent on GHB and GBL/1,4-BD. While this does seem to be quite rare, when someone develops a dependency it can be severe, with a rapid onset of unpleasant withdrawal symptoms which may include delirium, psychosis, tremor, insomnia and severe anxiety. Cravings are very common during detox and can be challenging to overcome.
GBL + Medications For Pain (Narcotic Drugs)
- Some people report using GHB and GBL to come down off other drugs, like MDMA.
- However, these drugs may not be tested for often as they can only be picked up on in a very short window (1–2 days) and can be unreliable.
- GBL is a prodrug of GHB, meaning that it is converted into GHB once ingested.
- Remember, drug checking can tell you what is in your drugs, but can’t tell you how strong they are.
- The effects and risks of GBL can depend on the frequency and amount of use, individual age, weight, and health, and the use of additional substances.
GBL is primarily used as an industrial solvent for cleaning oils, fats, and waxes from metal surfaces and removing textile adhesives. It is also used in the food industry as an extractant for flavors and fragrances, a solvent for dyes, and a chemical agent. GBL is used in the production of polymers, plastics, and resins, as well as in the production of pharmaceuticals and cosmetics. GHB presents cross-tolerance with 1,4-Butanediol and GBL, since these act as prodrugs for GHB. Cross-tolerance with alcohol and baclofen has been shown in rats,3536 and is likely with other GABAB-agonists.
How Can You Be Safer When Using GHB/GBL/1,4-BD?
While a small proportion of GBL drug overdose cases require ventilation in the intensive care unit (ICU), the great majority present in a coma, and after a few hours waken rapidly and are discharged. Dependent patients who present with an overdose may transition rapidly from intoxication to withdrawal. GHB, GBL and 1,4-BD can cause dizziness, extreme sleepiness, impaired judgement, and confusion, and people can appear ‘out of it’. 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.
These drugs can cause poor judgement and result in an increased risk of transmitting sexually transmitted infections like HIV because of not using condoms. 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. 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.
As such, it is essential to understand the chemistry behind the synthesis of GBL to ensure that it is produced safely and efficiently. 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. With doses of 10 mg/kg of GHB, they were decreased by 61% in the hippocampus region and 32% in the prefrontal cortex, and with 100 mg/kg, they were decreased by 38% and 9%, respectively. This paper demonstrates contradicting effects on neuronal loss, with lower doses (10 mg/kg) producing the most neurotoxicity, and higher doses (100 mg/kg) producing less.
Auditory Effects
GHB (gamma hydroxybutyrate), GBL (gamma butyrolactone) and 1,4-BD (1,4-Butanediol) are depressant drugs. GBL is a highly potent chemical; even small doses can be harmful. It can cause dizziness, nausea, vomiting, confusion, and loss of consciousness. It is also highly addictive, and long-term users may suffer from withdrawal symptoms such as anxiety, depression, and cravings.
Can GBL Be Detected In Your Body?
While they share many similarities, there are also important differences between the two substances, including their legal status, potency, and side effects. It is important to use caution when using either GBL or GHB, as they can be dangerous when misused or abused. 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.
Date Rape Drug
Lying in the recovery position can prevent one from suffocating on their own vomit. 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. 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. In many cases, traumatic experiences can result in a mental health disorder and substance abuse.
When GBL is mixed with alcohol, users may experience intensive breathing difficulties. The serious side effects of GBL include the inability to control the bowels, vomiting, mental changes, agitation, sedation, memory loss, serious breathing and heart problems, seizures, fainting, coma, kidney failure, and death. The effects can be made worse by alcohol or narcotics such as heroin, morphine, and others. After long-term use, abruptly stopping use of this substance may lead to withdrawal symptoms, including tremors, insomnia, and anxiety. 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.
