Ortetamine (INN), also known as 2-methylamphetamine, is a stimulant drug of the amphetamine class. In animal drug discrimination tests it substituted for dextroamphetamine more closely than either 3- or 4-methylamphetamine, although with only around 1/10 the potency of dextroamphetamine itself.[1]

Legal status

Sweden's public health agency classified 2-MA as a narcotic substance, on January 18, 2019.[2] Ortetamine is an isomer of Methamphetamine, therefore, a Schedule II Controlled Substance in the United States.
