Dimethocaine is often used as a legal substitute for cocaine. The drug is administered intravenously or nasally, as taking it would lead to rapid hydrolysis. [5] Its positive effects are euphoria, stimulation, increased conversational capacity and mood brightening. [6] However, because the drug acts in the same way as cocaine, it has comparable negative side effects. These side effects include: tachycardia, difficulty breathing, chest pain, vasoconstriction, insomnia, paranoia and anxiety. [6] Dimethocaine is likely to pose greater health problems than cocaine. This is due to the fact that more dimethocaine must be administered to create the same feeling of euphoria, which leads to an increased risk of negative effects. When a product sold online in the UK in June 2010 that was advertised as dimethocaine was tested, it turned out to be a mixture of caffeine and lidocaine,[3] and the absence of a dopaminergic stimulant ingredient in such mixtures could explain the limited recreational effects reported by many users. However, other samples tested were shown to contain true dimethocaine and it was found that a branded product containing `bath salts`, which mainly contains dimethocaine as an active ingredient, was particularly abused in Ireland by intravenous drug users. [4] When inhaled, dimethocaine begins to act in 10-30 minutes, with the highest effects at 60-120 minutes and up to 4-6 hours, there is an action phase with the „sequelae“. [11] Sequelae include fatigue and mild mental impairment.

[6] An abdominal constriction test was performed on mice at doses of 5, 10 and 20 mg/kg dimethocaine administered subcutaneously. This test showed dose-dependent anti-sociceptive responses induced, which are processes that block the recognition of a painful or harmful stimulus by sensory neurons. [9] (1996) The effects of systemic procaine, lidocaine and dimethocaine on nociception in mice. Dimethocaine and structurally related local anesthetics such as cocaine and procaine inhibit dopamine (DA) absorption by blocking dopamine transporters (DATs). [7] The dopamine transporter controls the dynamics of the neurotransmitter dopamine. This neurotransmitter controls many functions, including movement, cognition, and mood. Drugs such as cocaine and dimethocaine induce a dopamine overflow by inhibiting dopamine transporters, creating a euphoric effect. [8] In addition to inhibiting dopamine intake, dimethocaine has also been shown to inhibit the binding of CFT, another inhibitor of dopamine absorption. [7] These inhibitory properties are responsible for the stimulating effect of dimethocaine on the central nervous system. [5] In vivo and in vitro measurements of dopamine transporter activity have shown that dimethocaine is a potent and effective inhibitor of dopaminergic reuptake (also known as an indirect dopamine agonist). [7] These effects were mainly observed in the nucleus accumbens, a region of the basal forebrain. [5] A comparison of the pharmacological potencies of different local anesthetics gave the following potency order:[5] Products in Ireland included Mind Melt, Amplify, Amplifier, Mint and Mania.

An analysis of the substances confirmed the presence of dimethocaine in Amplify and Amplifier. It has sometimes been detected alongside a contaminant, desethyldimethocaine. (1996) Stimulating activities of dimethocaine in mice: reinforcing and anxiety-provoking effects. Cocaine > dimethocaine > tetracaine > procaine > chlorprocaine dimethocaine, also known as DMC or larocaine, is a compound with stimulating effects. This effect is similar to that of cocaine, although dimethocaine appears to be less potent. Just like cocaine, dimethocaine is addictive because of its stimulation of the reward pathway in the brain. However, dimethocaine is a legal substitute for cocaine in some countries and is even listed by the European Monitoring Centre for Drugs and Drug Addiction (EMCDDA) in the category „synthetic cocaine derivatives“. [1] The structure of dimethocaine, an ester of 4-aminobenzoic acid, is similar to that of procaine. It is found in the form of a white powder at room temperature. [2] In mice, the dose at which acute toxicity occurs with intravenous administration is 40 mg/kg and as a subcutaneous injection (injection into the skin layer just below the dermis and epidermis) is 380 mg/kg. [14] The lethal dose of dimethocaine for one mouse is 0.3 g per kilogram of body weight. [15] Like cocaine, dimethocaine inhibits the absorption of dopamine in the brain by disrupting dopamine transporters.

[13] The effectiveness of these drugs is related to their affinity for dopamine transporters and their ability to inhibit dopamine absorption. [7] The exact metabolic pathways of dimethocaine have not been studied, but the different metabolites have been studied in Wistar rats. After administration of dimethocaine, various metabolites were found and identified in their urine. Due to these metabolites, different metabolic pathways may have been postulated. The most important phase I reactions are ester hydrolysis, desethylation, hydroxylation of the aromatic system or a combination of these. [1] The most important phase II reactions are N-acetylation, glucuronidation and a combination of both. [5] [1] Various cytochrome P450 isoenzymes are involved in the early stages of human metabolism. N-acetylation is catalyzed by the isozyme NAT2. [12] (1993) Effects of cocaine-like discriminative stimuli of procaine, dimethocaine and lidocaine in rats. In studies with rhesus monkeys, dimethocaine`s affinity for dopamine transporters is lower than that of cocaine, while dimethocaine`s effectiveness in inhibiting dopamine absorption is similar. This means that more dimethocaine is needed to achieve a similar reaction.

Peak effects occurred within 10 to 20 minutes of the injection and fell to baseline levels within an hour. [13] There have been several cases where drugs other than dimethocaine have been sold, including tetracaine, lidocaine, ethylphenidate, caffeine, dimethylcathinone and methiopropamine. These reports were published between 2010 and 2016. In addition, administration of dimethocaine at non-toxic doses in mice has been shown to result in antinoziceptive reactions. [9] These reactions are thought to be caused, at least in part, by the effects of dimethocaine on the central nervous system. An effect of memory impairment observed in mice after administration of dimethocaine was thought to be due to a non-anesthetic mechanism of action. [10] Cocaine and other local anesthetics are known to produce cardiotoxicity by blocking sodium channels. However, no reports have been published on the same effects of cardiotoxicity associated with dimethocaine. [2] There is little research on the toxicity of dimethocaine in humans, and therefore the exact lethal or pharmacological doses are unknown. This article examines how cocaine was bought, sold and consumed in the years leading up to its legal ban. Many previous historical studies have focused on chronic anti-drug legislation with the dual intention of identifying the roots of contemporary drug policy and linking legislation to drug use trends and the experiences of drug users. However, this paper suggests that legislative developments alone cannot explain the changing patterns of cocaine sales and use.

Taking full advantage of the records of those who legally distributed cocaine, including doctors, retail prorogologists and drug manufacturers, this document argues that legal patterns of cocaine use and distribution changed significantly before prohibition. As a result of this transformation, cocaine was feared as a threat to society at the turn of the century. The response to these changes has been a vigorous attempt to enforce fair use standards through informal controls, such as voluntary restrictions on the sale of cocaine in pharmacies, and more formal methods such as police treatment of cocaine sellers and users as a public nuisance. These developments suggest that there were vaguely defined notions of „legitimate“ and „illegitimate“ sales and consumption that influenced the cocaine market, even though there were no laws formalizing these definitions. The impact of the public reaction has made cocaine`s status as a legal drug a small consolation for many users. Yes, crack is illegal. Crack is a List II substance under the Controlled Substances Act. Class II drugs, which include PCP and methamphetamine, are at high risk of abuse. Abuse of these drugs can lead to severe psychological or physical dependence. Another analysis of products from an online seller in the UK found that one of the dimethocaine products actually contained caffeine and lidocaine.
