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. 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.
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 (1). Naomi Carr is a qualified mental health nurse with several years of experience working with children and adults in the UK.

- Long-term use of GBL and GHB can also lead to physical and psychological dependence, making it difficult to stop using the drugs without experiencing withdrawal symptoms.
- 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.
- Some people who use the drug illicitly do so not for the euphoric effects, but rather use higher doses to help them sleep.
GBL can be addictive, especially if the drug is used regularly for a period of weeks or months. Taking GBL along with some medications for pain might cause severe side effects. Some medications for pain include meperidine (Demerol), hydrocodone, morphine, OxyContin, and many others.

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).

However, healthcare providers may sometimes use haloperidol to treat certain side effects or symptoms of withdrawal from GBL. It is also worth noting that these effects will not necessarily occur in a predictable or reliable manner, although higher doses are more liable to induce the full spectrum of effects. Likewise, adverse effects become increasingly likely with higher doses and may include addiction, severe injury, or death ☠. 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.

Even at low doses, most users will also experience somnolence and confusion, and as the dose-response curve is steep many regular users have experienced toxicity, with symptoms including nystagmus, aggression, urinary incontinence, and nausea.

It still has a reputation with younger people as being an alternative to ecstasy. There are GHB receptors in the CNS, but GHB also acts as an agonist at the gamma-aminobutyric acid B (GABAB) receptor. At low doses it has a euphoric effect, promoting confidence and reducing inhibition.
Alcohol (Ethanol) Interacts With GAMMA BUTYROLACTONE (GBL)
- Ensure the product is from a reputable source and not adulterated with other substances.
- GHB, GBL and 1,4-BD can cause overdoses that make you lose consciousness or stop breathing.
- When GBL is synthesized through a lipase reaction, the enzyme catalyzes the reaction between 4-HB and an alcohol such as ethanol.
- GBL is also highly soluble in water, so it should be kept from any excess moisture in the air.
- 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.
GBL has a faster onset of effects and longer duration compared to GHB. GBL is abused as a substitute for GHB due to its intoxicating effects. GBL/GHB is abused by teens and young adults as an alcohol substitute, at all-night parties and “raves,” and for enhanced sexual experiences. 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.

Cognitive Effects
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.
