Methamphetamines

<!--

3,4-Methylenedioxymethamphetamine (MDMA), commonly known as ecstasy (tablet form), and molly (crystal form), is an entactogen with stimulant and minor psychedelic properties.

Mephedrone, also known as ', , or , is a synthetic stimulant drug belonging to the amphetamine and cathinone classes. It is commonly referred to by slang names such as drone, , white magic, meow meow, and bubble'. Chemically, it is similar to the cathinone compounds found in the khat plant, native to eastern Africa.

Cathine, also known as -norpseudoephedrine or as (+)-norpseudoephedrine, is a psychoactive drug of the phenethylamine and amphetamine groups which acts as a stimulant. Along with cathinone, it is found naturally in Catha edulis (khat), and contributes to the overall effects of the plant. Cathine has approximately 7 to 10% of the potency of amphetamine.

Mebeverine is a drug used to alleviate some of the symptoms of irritable bowel syndrome. It works by relaxing the muscles in and around the gut.

Methcathinone (α-methylamino-propiophenone or ephedrone) (sometimes called "cat" or "jeff" or "catnip" or "M-Kat" or "kat" or "intash") is a monoamine alkaloid and psychoactive stimulant, a substituted cathinone. It is used as a recreational drug due to its potent stimulant and euphoric effects and is considered to be addictive, with both physical and psychological withdrawal occurring if its use is discontinued after prolonged or high-dosage administration. It is usually snorted, but can be smoked, injected, or taken orally.

Levomethamphetamine (INN: levmetamfetamine) is an optical isomer of methamphetamine primarily used as a topical nasal decongestant. Levomethamphetamine is used to treat nasal congestion from allergies and the common cold. It was first used medically as decongestant beginning in 1958 and has been used for such purposes, primarily in the United States, since then.

'''para-Methoxymethamphetamine (PMMA), also known as 4-methoxy-N-methylamphetamine (4-MMA'), is a serotonergic drug of the amphetamine family related to para''-methoxyamphetamine (PMA). It is the 4-methoxy analogue of methamphetamine.

Methedrone ('''para-methoxymethcathinone, 4-methoxymethcathinone, bk-PMMA, PMMC, methoxyphedrine, 4-MeOMC') is a recreational drug of the cathinone chemical class. Chemically, methedrone is closely related to para''-methoxymethamphetamine (PMMA), methylone and mephedrone. Methedrone received media attention in 2009 after the death of two young Swedish men. In both cases toxicology analysis showed methedrone was the only drug present in both men during the time of their overdose and subsequent deaths.

Methylephedrine, sold under the brand name Metheph among others, is a sympathomimetic medication described as an antiasthmatic agent and used to treat coughing and nasal congestion.

Famprofazone (Gewodin, Gewolen) is a nonsteroidal anti-inflammatory agent (NSAID) of the pyrazolone series which is available over-the-counter in some countries such as Taiwan. It has analgesic, anti-inflammatory, and antipyretic effects. Famprofazone has been known to produce methamphetamine as an active metabolite, with 15–20% of an oral dose being converted to it. As a result, famprofazone has occasionally been implicated in causing positives on drug tests for amphetamines.

Dimethylamphetamine (Metrotonin), also known as dimetamfetamine (INN), dimephenopan and '''N,N-dimethylamphetamine''', is a stimulant drug of the phenethylamine and amphetamine chemical classes. Dimethylamphetamine has weaker stimulant effects than amphetamine or methamphetamine and is considerably less addictive and less neurotoxic compared to methamphetamine. However, it still retains some mild stimulant effects and abuse potential, and is illegal in both the United States and Australia.

Methyl-DOB, or '''N-methyl-DOB, also known as 4-bromo-2,5-dimethoxy-N-methylamphetamine, MDOB, or M-154', is a psychoactive drug of the phenethylamine, amphetamine, and DOx families. It is the N''-methyl derivative of the psychedelic drug DOB.

Pholedrine, also known as '4-hydroxy-N-methylamphetamine and sold under the brand names Paredrinol, Pulsotyl, and Veritol' among others, is a sympathomimetic drug used in topical eye drops to dilate the pupil. It can be used to diagnose Horner's syndrome.

Metfendrazine (developmental code names HM-11, MO-482), also known as methphendrazine, is an irreversible and nonselective monoamine oxidase inhibitor (MAOI) of the hydrazine family. It was investigated as an antidepressant, but was never marketed.

6-MAPB ('1-(benzofuran-6-yl)-N-methylpropan-2-amine') is an entactogen of the benzofuran family which is structurally related to 6-APB and MDMA. It is known to be a serotonin releasing agent and, unlike MDMA, a potent serotonin 5-HT1B receptor agonist. The drug is not known to have been widely sold as a "designer drug" but has been detected in analytical samples taken from individuals hospitalised after using drug combinations that included other benzofuran derivatives. 6-MAPB was first encountered as a novel designer drug in 2013 and described in the scientific literature in 2014. It was bann

2-Fluoromethamphetamine (2-FMA) is a stimulant drug of the amphetamine family which has been used as a designer drug. 2-FMA is commonly compared to lisdexamfetamine (Vyvanse), and dextroamphetamine due to its efficacy as a study or productivity aid. 2-FMA is purported to produce somewhat less euphoria than comparable amphetamines, likely due to its main mechanism of action consisting of norepinephrine reuptake inhibition.

4-Fluoromethamphetamine (4-FMA) is a stimulant drug related to methamphetamine and 4-fluoroamphetamine. It has been reported to be sold as a designer drug, but little is known about its pharmacology or toxicology.

4-Methylmethamphetamine (4-MMA), also known as mephedrine, is a putative stimulant and entactogen drug of the amphetamine family. It acts as a serotonin–norepinephrine–dopamine releasing agent (SNDRA).
