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. Although it is not sedating like other date rape drugs, it has been used to facilitate sexual assault.4142 It can increase disinhibition and sexual desire.43 Often Ecstasy is combined with amphetamines or other drugs. The practice is commonly referred to as “party ‘n’ play” (PNP or PnP) by some participants, while others use the term “high ‘n’ horny” (HnH).
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. Reduce the amount you’re re-dosing with each time to lower your risk of overdose.
Medications For Pain (Narcotic Drugs) Interacts With GAMMA BUTYROLACTONE (GBL)
Light to moderate users often experience insomnia and sleep-related problems, whereas heavy, prolonged use can cause severe withdrawal symptoms similar to Benzodiazepine withdrawal syndrome (BWS). Both GBL and GHB can have serious side effects, especially when taken in high doses or in combination with other drugs. These side effects can include respiratory depression, seizures, coma, and even death.
Čo Je GHB?
GHB can be manufactured with little knowledge of chemistry by mixing another drug, GBL, with an alkali hydroxide such as sodium hydroxide, to form the GHB salt. Due to the ease of manufacture and the availability of its precursors, it is not usually produced in illicit laboratories like other synthetic drugs, but in private homes by low-level producers38 or GBL is simply consumed directly. 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. It will help you navigate the complicated process of GHB withdrawal, but it doesn’t address patterns of thought and behavior that contribute to drug use.
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. 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. 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.
What Are The Long-term Effects Of Using GHB/GBL/1,4-BD?
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. 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.
- People are most likely to vomit as they become unconscious, and as they wake up.
- They can also cause drowsiness, dizziness, and loss of coordination.
- This is especially the case for alcohol and other depressant drugs as effects become more intense and the risk of overdose increases.
- 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).
Gamma-Butyrolactone (GBL): All You Need To Know
Taking GBL along with alcohol might greatly increase sleepiness and drowsiness caused by alcohol. Be careful not to confuse GBL with gamma-hydroxybutyrate (GHB) or butanediol 1. Both drugs are often used recreationally in club settings to achieve a euphoric, disinhibiting effect and by bodybuilders to promote growth hormone production. The levels of lactonase enzyme can vary between individuals, meaning that first-time users can show unpredictable results, even from small doses.

Synthesizing gamma-butyrolactone (GBL), Cas # , is a complex process that involves several steps. The most common approach to synthesizing GBL is through acidification or lipase reaction using 4-hydroxybutyrate (4-HB), prepared through microbial fermentation. GBL has a low oral LD50, the amount of a substance that must be consumed to cause death in 50% of the test population.
Can GBL Addiction Be Treated On An Outpatient Basis?
Other symptoms of withdrawal include confusion, insomnia, delirium, and hallucinations. The onset of withdrawal can begin 1-2 hours after the last dose and can progress rapidly. GBL is two to three times as potent as GHB, and its effects are felt faster. This makes it a far greater risk for overdose than GHB, but both drugs can have serious downsides from overconsumption, up to and including coma and death. The drug was linked to almost 40 overdoses at a single music event in Melbourne, Australia, in 2017.
What Products Contain Gamma-butyrolactone?
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. Substance related deaths most commonly occur when combining depressants. Depressants affect the parts of the nervous system responsible for breathing, and an overdose or combination of these substances can result in fatal levels of respiratory depression.
Adverse Effects
Serotonin syndrome is a result of excess serotonin in the brain, which can cause seizures, anxiety, tremors, nausea, coma and possibly a deadly fever. Usually this is caused when a user has used an anti-depressant within the last 2 weeks of consuming said substance. These kind of antidepressants include monoamine oxidase inhibitors (MAOIs), serotonin reuptake inhibitors (SSRIs) and serotonin–norepinephrine reuptake inhibitors (SNRI).
- Studies on rodents have shown that GBL has low acute toxicity and only central nervous system depression has been highlighted.
- You might feel confused, have memory problems, have jitters or feel anxious, feel nauseous or dizzy, feel disinhibited or make risky decisions, feel anxious or paranoid, feel unable to stay awake, stumble or fall over or experience unwanted sexual arousal.
- GBL presents cross-tolerance with 1,4-Butanediol and GHB, since GBL and 1,4-Butanediol act as prodrugs for GHB.
- The differing levels of dehydrogenase enzymes can vary between individuals, meaning that, like alcohol, effects can differ greatly between users.
- Physically, it is a hygroscopic colorless oily liquid with a barely noticeable characteristic odor.
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. GBL can be synthesized from GHB through dehydration of the terminal hydroxy groups, forming a saturated lactone ring. Structurally, GBL is a five-membered ring with an oxygen substituent at R1, adjacent from the oxygen atom in the ring, forming a cyclic ester called a lactone. GBL has reportedly been used as date rape drug (as a legal alternative to GHB), in which it is secretly put dropwise into drinks but there is little evidence to support it being widespread, especially compared to alcohol due to its strong taste.
GBL Drug Long Term Effects
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. It has also been used in the treatment of alcohol and opiate addiction.
