Drugs GBL itself is pharmacologically inactive, but it is converted in the body by lactonases to GHB, the active agent. Because it is more lipophilic than GHB, GBL is absorbed more rapidly after oral administration and has a faster onset of action than GHB. GHB occurs naturally in the central nervous system (CNS) and is presumed to be a neurotransmitter 3. Internet posts by men seeking PnP experiences often resort to slang to identify what drug they are partying with.1415 These drugs tend to inhibit penile erection,1112 a phenomenon known by the slang term crystal penis or tweaker dick. Consequently, many men who engage in PnP use erectile dysfunction drugs such as sildenafil, vardenafil, and tadalafil.16 Imodium is often taken by participants in passive anal sex in order to be clean for longer. GHB and GBL testing windows can change depending on how much you have taken, how often and your individual body.

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.
Medications For Pain (Narcotic Drugs) Interacts With GAMMA BUTYROLACTONE (GBL)
It is important to speak with a medical professional first if you are worried about withdrawing from these drugs. A variety of 1,4-butanediol derivatives are GHB-like drugs or GHB receptor agonists. 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).

Is Gamma Butyrolactone Illegal?
One publication investigated 226 deaths attributed to GHB.19 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. 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. Gamma-Hydroxybutyric acid (also known as and 4-hydroxybutanoic acid and GHB) is a depressant substance. 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.
Other routes are from butadiene, allyl acetate and succinic acid. 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.
- It is used in various industrial solvents, such as those found in paint thinners and cleaning products.
- As the serotonergic system may be involved in the regulation of sleep, mood, and anxiety, the stimulation of this system by high doses of GHB may be involved in certain neuropharmacological events induced by GHB administration.
- People who are dependent on or addicted to GBL may benefit from professional advice and treatment.
- GBL can cause many short-term and long-term risks and can lead to dependence and addiction.
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.
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. 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.
What Is Gamma-Butyrolactone (GBL)?
Accidental ingestions of GBL have also occurred due to inadequate storage methods. If GBL is put into a clear liquid, glass, or bottle, it can be easily mistaken for water. It is recommended to clearly label your GBL in writing and dye the liquid with blue food coloring so it no longer resembles a drinkable beverage.

Withdrawal
You can test GHB, GBL and 1,4-BD yourself with some reagent tests or at a drug checking clinic with a spectrometer. How reliable these tests are can depend on how concentrated your drug is. If it has been mixed with lots of water, it may be hard for the spectrometer to detect it.
Benzodiazepines
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. In conclusion, GBL and GHB are two closely related chemicals that have similar effects on the 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.
The effects usually last up to 4 hours, after which you may start to experience a comedown period. The effects may last for a much longer period if you use GHB or GBL regularly, mix it with other drugs or take very large doses. In people who have used GHB or similar drugs regularly for a long time, ‘cold turkey’ withdrawal can sometimes be dangerous.
If you or a loved one are struggling with long-term drug abuse and a co-occurring mental health condition such as depression, contact one of our helpful treatment specialists today. We Level Up can provide information on dual diagnosis and detox programs that may fit your specific needs. Taking haloperidol along with GBL might cause serious side effects.

Cognitive Effects

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.
GHB and GBL are sometimes referred to as G, Liquid Ecstasy, Liquid X, Juice or Geebs. 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.
- Activation of both the GHB receptor and GABAB is responsible for the addictive profile of GHB.
- It is used as a sedative and hypnotic, as an anesthetic, and as an antidepressant.
- However, both substances have a high potential for abuse and are classified as controlled substances in many countries.
- If you have been given these drugs without your knowing and are expecting a drug test for work or court, you can speak to a medical professional or Police about your next steps.
- Like gamma-hydroxybutyric acid, butane-1,4-diol is safe only in small amounts.
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.
