Methcathinone (α-methylamino-propiophenone or ephedrone) (sometimes called “cat” or “jeff” or “catnip” 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.
Methcathinone is listed as a Schedule I controlled substance by the Convention on Psychotropic Substances and the United States’ Controlled Substances Act, and as such it is not considered to be safe or effective in the treatment, diagnosis, prevention, or cure of any disease, and has no approved medical use. Possession and distribution of methcathinone for the purpose of human consumption is illegal under any/all circumstances in the United States and is either illegal or highly regulated in most jurisdictions world-wide.
Methcathinone was first synthesized in 1928 in the United States and was patented by Parke Davis in 1957.It was used in the Soviet Union during the 1930s and 1940s as an anti-depressant (under the name Эфедрон—ephedrone). Methcathinone has long been used as a drug of abuse in the Soviet Union and Russia.
Circa 1994, the United States government recommended to the UN Secretary-General that methcathinone should be listed as a Schedule I controlled substance in the Convention on Psychotropic Substances.
In parts of Europe this drug is not listed as a dangerous drug and is under review by the authorities in the United Kingdom where at the moment it is a Class B drug. They want it reclassified as a class A drug when it is dissolved in water for injection use just as amphetamine is.
