Contrary to popular belief, toxicologists did not find a trace of the components in bath salts during the investigation into the cannibal attack in Miami during the attacker`s autopsy.  But some scientists doubt the claim that no bath salts were involved in the ordeal, saying that due to the meagre testing possibilities, a bath salt might have gone unnoticed.  „We are very pleased with the speed with which Health Canada has been able to address this issue and plan the MDPV under the Controlled Drugs and Substances Act, so that it is now illegal and police can deal with it more effectively,” he said. The ban „is an important step in preventing organized criminals from preventing organized criminal groups from acquiring and profiting from this illegal substance,” Franks said in a statement. MDPV is now in the same category as cocaine and heroin, which means that it is only legal to use it for authorized scientific and research activities. The new classification gives police the power to investigate „suspected illegal activities related to the MDPV,” according to a written statement from Health Canada. A bottle of the drug „bath salts” can be seen after a press conference in Ottawa on Tuesday, June 5, 2012. (Adrian Wyld / THE CANADIAN PRESS) The Canadian Association of Chiefs of Police called Wednesday`s ban announcement „an important step to prevent organized criminal groups from acquiring and profiting from this illicit substance.” MDPV should not be confused with bath salts that are added to the bath and can be purchased at pharmacies and retailers. Bath salts are a powdered drug that contains at least one amphetamine-like substance. In the UK, all substituted cathinones were declared illegal under the Drug Abuse Act 1971 in April 2010, but other synthetic drugs such as naphyron appeared soon after and some products described as legal contained illegal compounds.  To avoid being controlled by the Drug Act, synthetic drugs such as mephedrone have been described as „bath salts” or other misnamed names such as „plant foods,” although the compounds have not been used for these purposes in the past.    Very little is known about how bath salts interact with the brain and how they are metabolized by the body.
Scientists tend to believe that bath salts have a high addictive potential and can increase user tolerance.   They are similar to amphetamines in that they produce stimulating effects by increasing the concentration of monoamines such as dopamine, serotonin and norepinephrine in synapses.   They are generally less able to cross the blood-brain barrier than amphetamines due to the presence of a beta-keto group that increases the polarity of the compound.  In the summer of 2012, a moral panic began over the use of „bath salts,” a new synthetic drug popular in Canada, the United States and Europe. The drug, so called because its white crystals can resemble Epsom salts, has been blamed for people participating in such incredulous acts as cannibalism, self-harm and violence against others. However, the most surprising fact that the public learned about this new drug was that it was actually completely legal and that it was sold online or over-the-counter in small independent stores such as gas stations and convenience stores. The reputation of these drugs as „legal highs” also gave users the false impression that the drugs were safe to use (Smith and Cardile, e7), although they may actually have serious medical effects such as tachycardia, high blood pressure, hyperthermia, seizures, and death (Ross et al., 967). Bath salts made international headlines in May after media suggested the perpetrator of a facial attack in Miami was relying on bath salts.
However, it eventually emerged that there was only marijuana in the attacker`s system. „These bath salts represent a real and current danger to Canadians and the Canadian public. That`s why we`ve given law enforcement the tools they need to remove these products from our streets and from those who may not know how harmful they are,” Aglukkaq said. A brutal attack in Miami in May, in which a man chewed on another man`s face, was initially attributed to bath salts, although tests later revealed that the attacker had only marijuana in his system. Under new federal rules announced on September 26 by Health Minister Leona Aglukkaq, methylenedioxypyrovalerone (MDPV), the main ingredient in bath salts, has been banned in Canada. Two other drugs sometimes used to make bath salts – mephedrone and methylone – are already banned in Canada. It is now illegal to possess, exchange, import or export MDPV, the drug often found in „bath salts,” the federal government announced Wednesday. „This means that it is illegal to produce, sell, import or possess MDPV unless it is allowed by regulations that make it difficult for people to trade or manufacture these so-called `bath salts`,” Aglukkaq said.
Incidents of bath salt violence have recently been reported in Calgary and Toronto. Bath salts contain a number of amphetamine-like chemicals, including MDPV, a synthetic cathinone similar to the active ingredient khat, which is chewed in parts of East Africa and Yemen. To protect citizens from these serious health effects, various lawmakers have fought to ban these „synthetic drugs.” The seemingly harmless term „bath salts” may include a variety of synthetic drugs made from different combinations of different ingredients. Lawmakers are struggling to keep up, because once they ban an ingredient, drug manufacturers can adjust the formula to make something that isn`t covered by the new laws (Vargas-Cooper). This game of cat and mouse has been a danger to the public because users can never be sure what they are taking, and doctors facing suspected overdoses have no idea what chemicals they were dealing with and how to treat their patients. Due to the novelty of the drug, it is also rarely detected in routine screenings (Smith and Cardile, ibid.). The main ingredient in a new, highly addictive street drug known as „bath salts” has been banned in Canada. Health Minister Leona Aglukaag announced Wednesday that MDPV, a powerful stimulant, is now „illegally owned, traded, imported or exported unless authorized by law.” The main ingredient in bath salts, a psychotropic synthetic drug, is now illegal.
Bath salts or monkey dust are in powder form or crystallized, which can be swallowed, smoked, injected or sniffed. The subjective effects are similar to those of MDMA or cocaine, but lasting 5 to 6 hours. Both substances cause rapid onset of action in the central nervous system, and stimulating toxicity. At higher doses, this class of substances can produce effects similar to those of serotonin syndrome.  Due to their rapid appearance, synthetic cathinones are powerful rewards/enhancers with high addictive potential.  „Monkey dust”, „bath salts” or plant foods are often used simultaneously with conventional psychotropic drugs. Users who have taken an overdose often experience symptoms of restlessness, delirium, hallucinations, excessive motor activity, seizures, tachycardia, high blood pressure, and/or hyperthermia.  Pharmacologically, bath salts typically contain a cathinone, typically methylenedioxypyrovalrone (MDPV), methylone or mephedrone; However, the chemical composition varies considerably, and products labelled with the same name may also contain pyrovalerone or pipradrol derivatives. In Europe, the main synthetic cathinone is mephedrone, while in the United States, MDPV is more common.
 As a result, the Canadian government recently banned one of the most commonly used ingredients in bath salts, methylenedioxypyrovalerone (MDPV), which follows in the footsteps of many U.S. states and the United Kingdom. MDPV is now recognized in Canada as a List I substance under the Controlled Drugs and Substances Act and assigns it the same category as heroin and cocaine. However, there are concerns that banning a previously legal chemical could affect scientific research and that Canada could have done better by implementing educational efforts and regulating the sale of the drug (Soupcoff). It remains to be seen whether this approach will effectively help protect the safety and health of Canadians, or whether the policy will be a disadvantage by pushing the practice underground and unregulated. The drug has earned the nickname „bath salts” because the finished product resembles Scented Bath Salts of Epsom.
