Data from the Drugs Information and Monitoring System (DIMS) and the Dutch Poisons Information Centre (DPIC) were combined and jointly analyzed. The number of drug samples submitted to DIMS for analysis containing NPS increased from 22 in 2007 to 431 samples in 2013. The most frequently submitted NPS in 2013 included 4-bromo-2,5-dimethoxyphenethylamine (2C-B), 4-fluoroamphetamine (4-FA), methoxetamine (MXE) and 6-(2-aminopropyl)benzofuran (6-APB). From 2012 onwards, the number of NPS bought as drug of choice exceeded those appearing as adulterants in established drugs. The DPIC was consulted about 35 NPS exposures in 2013, most frequently involving 4-FA, mephed…
An In Vitro Study Of The Neurotoxic Effects Of N-Benzylpiperazine: A Designer Drug Of Abuse
Before going into a coma, she consumed 10 liters of water in just 15 hours. The young woman experienced high blood pressure and brain swelling prior to her death. At doses of 20 milligrams to 100 milligrams, BZP and TFMPP reportedly produce a range of mental experiences lasting six to eight hours.
Reactions With Other Drugs Or Substances
Amphetamine-like effects include euphoria, alertness, a reduced need for both food and sleep, a heightened sense of touch and other pleasurable sensations, and a sense of emotional closeness with others. At higher doses, though, users have reported stomach pain, vomiting, and feelings of extreme anxiety and paranoia. A tingling feeling on the surface of the skin may make users feel as if insects are crawling all over them. Some users end up in emergency rooms panic-stricken, screaming, and suffering from extreme dehydration. The U.S. Drug Enforcement Administration reported that the typical abusers of BZP and TFMPP are “adolescents and young adults involved with the current rave culture.” Of particular concern is the fact that many of its users do not even know they are taking it. Not only have BZP and TFMPP tablets been found among bags of ecstasy (MDMA) tablets, the powders of all three drugs have been found mixed together in drugs being passed off as pure ecstasy.
Conclusion Findings suggest that young people in this study were not suffering excessive or dangerous adverse effects. However, potentially risky use of these products raises the issue of the need for developing harm reduction interventions. Over the last decade, New Zealand has led the world in the legal sale and uncontrolled use of the recreational drug benzylpiperazine (BZP), the active ingredient of ‘party pills’. One survey found that 40% of 18Á29-year-olds admitted to using BZP-based party pills while, in another study, 44% of first-year university students had used the drug. During the period it was legally available for sale, BZP usage in New Zealand far exceeded the usage of any illicit drugs other than cannabis.
In Vivo Interactions Between BZP And TFMPP (party Pill Drugs)
In the late 1990s, BZP emerged in New Zealand as a ‘legal alternative’ for MDMA and methamphetamine 3. In Europe, its use was first reported in Sweden in 1999, but it only became widespread as a NPS from 2004 onwards until controls over the substance were introduced in 2008, in the European Union 4. Amphetamines are illegal without a prescription from a medical doctor. Department of Justice, “BZP is about 10 to 20 times less potent than amphetamine.” However, just one or two BZP tablets can have extreme negative effects on the people who take them.
Former speed addicts who took BZP experienced an increase in blood pressure and short-term mental experiences similar to those brought on by amphetamines. These data suggested that BZP was likely to be addictive and abused. Results of experiments conducted on rhesus monkeys, published in Drug and Alcohol Dependence in 2005, confirmed that BZP is as addicting as amphetamines. TFMPP taken alone, however, was not considered likely to be abused. Other animal experiments suggest that the use of piperazines can actually inhibit learning. Because they affect the brain, the drugs cause a wide range of sensations and experiences.
Other Products Of Interest:
Stimulants mediate the actions of dopamine, norepinephrine and/or serotonin, mimicking the effects of traditional drugs such as cocaine, amphetamine, methamphetamine, and ecstasy. Opioids belong to a chemically diverse group of central nervous system depressants. They bear structural features that allow binding to specific opioid receptors, resulting in morphine-like effects e.g. analgesia. The survey consisted of a random national household sample of 2,010 people aged years old collected using the Centre for Social and Health Outcomes Research and Evaluation (SHORE) and Whariki’s in-house computer assisted telephone interviewing (CATI) system. The need for emergency room treatment rose considerably by 2004 among users of BZP and TFMPP.
Legal Status
TFMPP, used in conjunction with BZP, has been reported to produce some of the effects of MDMA, but with a lower potency 11, while mCPP has been indicated to produce similar stimulant and hallucinogenic effects as MDMA 12. Piperazines have been described as ‘failed pharmaceuticals’, as some had been evaluated as potential therapeutic agents by pharmaceutical companies but never brought to the market 1. One piperazine that has been commonly used as NPS is 1-benzylpiperazine (BZP) though other piperazine derivatives have also been reported. These include among others 1-(3-chlorophenyl) piperazine (mCPP), 1-(3-trifluoromethylphenyl) piperazines (TFMPP), 1-benzyl-4-methylpiperazine (MBZP), 1-(4-fluorophenyl) piperazines (pFPP) and 1-cyclohexyl-4-(1,2-diphenylethyl) piperazine (MT-45). In countries such as New Zealand where BZP and related piperazines have been made illegal, there is now increasing commercial interest in piperazine-free “party pills” which are purported to produce similar effects with ingredients that will circumvent the ban.
In the mass spectrum, the principal ions (m/z) of mCPP are 154 (base peak), 196, 156, 56 and 138. However, mass spectrometry does not distinguish mCPP from its isomers (oCPP and pCPP). Consumption of BZP and other piperazine derivatives is mainly by ingestion.
Benzylpiperazine/Trifluoromethyl-phenylpiperazine
The combination of BZP and TFMPP induced similar subjective effects, along with well-characterized dexamphetamineand MDMA-like effects. Background This study aimed to investigate patterns and context of use of BZP-party pills, function of use, and positive and negative effects experienced by a sample of New Zealand young people who had used the products. Methods A qualitative study comprised of semi-structured interviews and group discussions. Results The sample included 58 young people aged 17–23 years who had used BZP-party pills in the previous 12 months.
- As of 2005, use among humans was limited to the treatment of parasitic worm infections.
- These systems are prone to genetic polymorphisms, so potential inter-individual differences may occur.
- Basic pharmacokinetic properties are described for both BZP and TFMPP when taken alone and in combination.
- Victoria, the last state in which it was legal, changed its classification on 1 September 2006,42 when BZP and piperazine analogs become illegal in the federal schedules, which are enacted by all Australian states and territories.

In many cases, users are unaware of the dosage of the tablets they take, which increases the risk of overdose and even death. Because piperazine abuse has been recognized only recently, specific programs for rehabilitation have not yet been developed. Treatment will most likely include psychological counseling. Until March of 2004, piperazines were considered legal in the United States. Piperazines sold in bulk over the Internet made their way to the club and rave scene.

We sought to assess more comprehensively the results of such decisions for newly emerging drugs. Findings (i) The rate of emergence of new drugs has been fairly steady. (ii) There is broad cross-national agreement on what should be scheduled. (iv) Temporary bans that delay final decisions by months can sometimes allow final decisions to be grounded on a substantially expanded research base.
Neither BZP nor any other piperazines are under international control, although several (BZP, TFMPP, mCPP, MDBP) were pre-reviewed by the WHO Expert Committee on Drug Dependence in 2012. Several countries have introduced national control measures over piperazines. Peters, F.T., Schaefer, S., Staack, R.F., Kraemer, T., Maurer, H.H.
Piperazines have been found to act as stimulants as a result of dopaminergic, noradrenergic, and predominantly serotoninergic effects produced in the brain. The majority of pharmacological studies of piperazines have focused on BZP and have indicated that it produces toxic effects similar to amphetamine and other sympathomimetics. According to animal studies, its effects are less potent than amphetamine, methamphetamine and MDMA 10.
Latest Data
There has been little research, to date, on the neurological consequences of high dose or chronic exposure of BZP. Here we provide a comprehensive review of the information currently available on BZP and suggest a need for further research into the mechanisms of action, long-term effects and potentially addictive properties of BZP. 1-Benzylpiperazine (BZP; see Molecular structure 1) is one of a small group of benzyl-substituted piperazines, but a much larger group comprises the phenylpiperazines (see Tables 1 and 2). Despite claims by some tablet and capsule suppliers that they are herbal products, piperazine and its derivatives are synthetic substances that do not occur naturally. The large-scale misuse of certain piperazine derivatives (often known as ‘party pills’) started in New Zealand several years ago, but became common in Europe only after 2004. BZP is a central nervous system (CNS) stimulant with around 10 % of the potency of d-amphetamine.
Several studies have shown that these drugs cause several drug-drug interactions. Following oral administration of mCPP to healthy human male volunteers, the elimination half-life ranges from 2.6 to 6.1 hours with a wide variation in peak blood levels and bioavailability. The hydroxy metabolites are partly excreted as the corresponding glucuronides and/or sulphates, and the chloroanilines are partly excreted as the acetylated derivatives. Physiological and subjective effects reach their peak 1 to 2 hours after oral administration and can last 4 to 8 hours. The negative effects of mCPP, often typical of a serotonin syndrome, include anxiety, dizziness, confusion, shivering, sensitivity to light and noise, fear of losing control, migraine and panic attacks. The subjective effects of mCPP and MDMA are somewhat comparable, but unlike MDMA and BZP, mCPP has little effect on the dopaminergic system.
