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. Like gamma-hydroxybutyric acid, butane-1,4-diol is safe only in small amounts. Adverse effects in higher doses include nausea, vomiting, dizziness, sedation, vertigo, and potentially death if ingested in large amounts. Anxiolytic effects are diminished and side effects increased when used in combination with alcohol.
If you have taken GBL for more than seven days in a row, Do not attempt to stop by yourself. Gamma-Butyrolactone (GBL) is an industrial chemical and is available for legitimate use in industry. However, if someone supplies or possesses them knowing or believing that they will be swallowed and ingested, they are committing an offense. GBL is typically marketed for sale as a cleaning solvent or polish. GBL is usually swallowed in its liquid form, often mixed with water or a soft drink.
Further, never mix GBL with alcohol or other drugs, as this could lead to serious health complications. As with any drug, it is important to be aware of GBL’s potential risks and use it responsibly. If you are considering using GBL, speaking with a qualified healthcare professional to ensure it is safe and appropriate for your circumstance is essential. Additionally, if you have a history of addiction or mental illness, seeking treatment before using GBL is essential. 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.
- GHB-induced stimulation may be due to this increase in tryptophan transport to the brain and in its uptake by serotonergic cells.
- Or you may end up in situations where you are not sober enough to enthusiastically gain or give consent.
- One publication has investigated 226 deaths attributed to GHB.13 Seventy-one deaths (34%) were caused by GHB alone while the other deaths were from respiratory depression caused by interaction with alcohol or other drugs.
- Due to its potential for misuse and abuse, GBL is tightly regulated in many countries and is available only through a prescription or with a valid license.
- You can become addicted to GHB and GBL and experience unpleasant effects when you stop taking it.
Recreational Use And Sought-after Effects
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. 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.
- Finding reliable suppliers can be difficult, but there are a variety of ways to locate suppliers.
- The synthesis of GBL is an essential process in manufacturing pharmaceuticals, chemicals, plastics, and other products.
- Dependent patients who present with an overdose may transition rapidly from intoxication to withdrawal.
- However, if someone supplies or possesses them knowing or believing that they will be swallowed and ingested, they are committing an offense.
- For this reason, it is recommended to only transport and store the drug using a glass container, standard gelatin capsules (not vegetarian), or high-density polyethylene plastic (also known as #2 recyclable plastic).
- Taking GBL along with some medications for pain might cause severe side effects.

GBL (gamma-butyrolactone) and GHB (gamma-hydroxybutyrate) are both central nervous system depressants that are commonly used as recreational drugs. GBL is a prodrug of GHB, meaning it is converted into GHB once ingested. Both substances have similar effects, including euphoria, relaxation, and sedation.
Addiction

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. However, it can become dangerous when used as a recreational drug or abused.
Chemical Structure

Cravings are very common during detox and can be challenging to overcome. Constant medical care provided during inpatient drug treatment helps prevent relapse. Clinicians can provide necessary medication and medical expertise to lessen cravings and the effects of GHB withdrawals. However, converting GBL into GHB is redundant because the body will rapidly metabolize the GBL into GHB after ingestion. Once that happens, the risks and effects of GBL are identical to GHB.
How To Be Safer When Using GHB/GBL
Although many substances are safe on their own, they can become dangerous and even life-threatening when combined with other substances. Certain combinations may be safe in low doses of each but still increase the potential risk of death. Independent research should always be done to ensure that a combination of two or more substances is safe before consumption.
Dependent users may experience a severe withdrawal reaction when the drug is stopped. The elimination half-life of GHB is about 20 minutes, and GHB intoxication has the unusual property that people can progress from deep coma to wakefulness over about 30 minutes. 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.
Withdrawal
10 Following withdrawal, treatments to help people in GBL addiction recovery can include rehabilitation services, psychotherapy, behavioral therapy, or medications. If you are experiencing withdrawal GHB, it’s crucial to first get an accurate assessment of all the symptoms. When the symptoms have been evaluated by a mental health professional, it may be determined that another form of mental condition is present and needs a particular type of treatment. Very often, some combination of psychotherapy, medication, and/or lifestyle changes are effective for coping with functional. Everyday use can result in a heightened tolerance to, and dependence on, the drug. When dependence begins, it tends to result in strong cravings, depressed moods, insomnia, and anxiety unless the user takes a dose every few hours.
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.

Drinking GHB or GBL on its own would lead to chemical burns in your mouth and throat. Because of this, people take GHB and GBL orally by using a pipette, syringe or pre-measured vial to measure the dose and then mix it into a soft drink. 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.
Health Risks And Side Effects

To avoid a possible overdose of GHB/1,4-Butanediol, it is important to start with a low dose and work your way up slowly by increasing the dosage in small increments as the exact toxic dosage is unknown. 1,4-Butanediol is classified as a subclass of alcoholic compounds called diols. Diols are named for having two alcohol (OH-) substitutions in their structure.
What Is The Benefit Of Gamma-butyrolactone?
Death may also occur when a victim falls into deep enough unconsciousness to aspirate on their own vomit. 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.
