One, developed by two Tel Aviv University researchers, is a sensor for gamma-hydroxybutyric acid and ketamine, but appears similar to a straw, and sends a text to the user's phone to warn them. Several devices have, in recent years, been developed to detect the presence of date rape drugs, many designed with discreetness in mind. A 26-month study of 1,179 urine samples from suspected drug-facilitated sexual assaults across the United States found 4% positive for GHB. From 1996 to 1999, 22 reports of GHB being used in drug-facilitated sexual assaults were made to the United States Drug Enforcement Administration. Although Rohypnol's use in drug-facilitated sexual assaults has been covered extensively in the news media, researchers disagree about how common such use actually is. Rohypnol is believed to be commonly used in drug-facilitated sexual assaults in the United States, the United Kingdom, and throughout Europe, Asia and South America. sayfailed verification all major American urban and regional newspapers covered date rape drugs, with headlines such as "Crackdown sought on date rape drug" (Los Angeles Times) and "Drug zaps memory of rape victims" (San Francisco Chronicle). Another, designed by four North Carolina State University students, is a nail polish that changes color in the presence of date rape drugs.|In higher doses, it causes similar central nervous system (CNS) depressant effects to other GABA-related substances, including benzodiazepines, although its mechanism of action differs. A wide variety of options are available to help the person stop using drugs or alcohol and avoid serious side effects from substance abuse. We are not doctors or substance misuse professionals, rather a group of gorgeous informed gay men, passionate about sex and our health, with direct experience of drug use, addiction, withdrawal, and recovery.}
Ritonavir (Norvir) Interacts With Gamma Butyrolactone (GBL)
Men in the chemsex scene have stated that sexual consent is not clearly defined and there can be a perception that anyone at a "party and play" get-together is assumed to consent. The same drug-induced loss of inhibitions makes PNP enthusiasts more vulnerable to more immediate threats, such as robbery, date rape, assault, or murder, by someone whom they meet for sex. GHB/GBL and crystal meth can also increase the risk of injuries due to accidents or sexual encounters that go wrong. Internet posts by men seeking PnP experiences often resort to slang to identify what drug they are partying with. Methamphetamine is used to create euphoria, "heighten sexual appetite", and increase sexual stamina. In some cases, these sexual encounters will sometimes occur continuously for several days along with repeated methamphetamine use.
In November 2020 the Advisory Council on the Misuse of Drugs advised that GHB should become a Class B drug rather than Class C – see Assessment of the harms of gamma-hydroxybutyric acid, gamma-butyrolactone, and closely related compounds – November 2020. They are pro-drugs of the Class C drug gamma-hydroxybutyrate (GHB), meaning that when either substance is ingested it is rapidly converted to GHB. Its effects have been noted in clubs with incidents reported of people losing consciousness and the use of the drug as a 'spiking' agent in sexual assaults. Taken in strong doses or with alcohol, the effects of GHB can be physically disabling. What may be a normal dose for one user could be a dangerous overdose to another user, tolerance can develop very quickly and it is dangerous to mix either drug with alcohol or any CNS depressant. To reduce risk of overdose users should only take smaller doses after their first dose, having given enough time to feel the effects reach their peak .

GBL/GHB is abused by teens and young adults as an alcohol substitute, at all-night parties and “raves,” and for enhanced sexual experiences. Injecting drugs GBL is dangerous. Dependent users may experience a severe withdrawal reaction when the drug is stopped. At low doses it has a euphoric effect, promoting confidence and reducing inhibition.

According to The Blade, the study specifically ignored an Ohio statute that excluded "situations where a person plies his intended partner with drink or drugs in hopes that lowered inhibition might lead to a liaison." The author of the study later admitted that the wording of the survey had been ambiguous. Alcohol, consumed voluntarily, is the most commonly used drug involved in sexual assaults. A 2009 Australian study found that of 97 instances of patients admitted to hospital believing their drinks might have been spiked, illicit drugs were detected in 28% of samples, and nine cases were identified as "plausible drink spiking cases".
Are You Taking GHB Or GBL On Its Own?
In the 1970's, GHB was recommended for the treatment of narcolepsy, though it was also found to be an ineffective and unpopular form of treatment primarily due to its euphoric side-effects. GBL and 1,4-BD have therefore been controlled as Class C drugs . In the 1970's, GHB was recommended for the treatment of narcolepsy/cataplexy, though it was again found to be flawed, primarily due to its euphoric side effects.

It converts to GHB in the body rapidly after ingestion and therefore, causes very similar effects to GHB. FDA warning against products containing GHB and its prodrugs, such as GBL. GBL overdose can cause severe sickness, coma and death.
- GBL is physically addictive and stopping it without medical supervision can be fatal; sudden withdrawal poses dangerous health risks and can require an in-patient detox.
- It is a colorless, oily liquid with a bitter taste.
- Abruptly stopping chronic GBL use can increase the severity of withdrawal symptoms.
- Studies indicate that individuals participating in such activities have a higher likelihood of acquiring sexually transmitted infections, including HIV/AIDS, due to unprotected sex with numerous partners.
GBL Side Effects
To detect GHB in urine, the sample must be taken within four hours of GHB ingestion, and cannot be tested at home. There have been several high-profile cases of GHB as a date-rape drug that received national attention in the United States. GHB became known to the general public as a date-rape drug by the late 1990s.
Health Risks And Side Effects
A review of the details of 194 deaths attributed to or related to GHB over a ten-year period found that most were from respiratory depression caused by interaction with alcohol or other drugs. GHB has been used as a club drug, apparently starting in the 1990s, as small doses of GHB can act as a euphoriant and are believed to be aphrodisiac. Some prodrugs, such as γ-butyrolactone (GBL), convert to GHB in the stomach and bloodstream. Recreational doses generally provide a feeling of euphoria, and larger doses create deleterious effects such as reduced motor function and drowsiness. Γ-Hydroxybutyric acid, also known as gamma-hydroxybutyric acid, GHB, or 4-hydroxybutanoic acid, is a naturally occurring neurotransmitter and a depressant drug.
Drugs Of Abuse
A 16-year-old boy with severe gamma-butyrolactone (GBL) withdrawal delirium. Near-fatal persistent anion- and osmolal-gap acidosis due to massive gamma-butyrolactone/ethanol intoxication. Pentobarbital for severe gamma-butyrolactone withdrawal. A case of withdrawal from the GHB precursors gamma-butyrolactone and 1,4-butanediol. For those users who do report withdrawal symptoms upon quitting the use of GHB or GBL, symptoms seem to depend on the dosage and the length of time the drug was used. In many people, quitting or temporarily abstaining from use of the drugs is achieved with minimal or no difficulty.
The following effects may begin within 15 to 20 minutes of taking GHB and may last for around 3 to 4 hours . The effects start after about 10 minutes to an hour and can last for up to seven hours or so . Orally, usually in small doses such as a teaspoon (5ml) at a time . As a result, there is no definitive way for users to know how strong a particular form of GHB is, thereby increasing the risk of an overdose. Like other drugs (e.g., ecstasy, marijuana) the chemical composition of GHB is highly variable, and sold in a wide range of concentrations. Users can experience strong wakefullness about 4 hours after the last dose was consumed.
The sedative properties of GHB and its related compounds, as well as their neutral odour and taste have led some to link the drugs to instances of drug-facilitated sexual assault, although the extent of the drugs’ use in these crimes remains unclear. 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. The risks are increased if combined with alcohol or other depressant substances. Different people will be more or less sensitive to the effects, just as with alcohol.
GHB acts as a central nervous system (CNS) depressant with effects similar to those of barbiturates. It is a hygroscopic, colorless, water-miscible liquid with a pleasant odor.
