Cathine
Cathine, also known as D-norpseudoephedrine and (+)-norpseudoephedrine, is a psychoactive drug of the phenethylamine and amphetamine chemical classes which acts as a stimulant. Along with cathinone, it is found naturally in Catha edulis (khat), and contributes to its overall effects.[2] It has approximately 10–14% the potency of amphetamine.[2]

Pharmacology
Like amphetamines, cathinone, and ephedrine, cathine acts as a norepinephrine releasing agent (NRA).[2] It also acts as a dopamine releasing agent (DRA) to a lesser extent.[2]
Chemistry
Cathine is one of the four stereoisomers of phenylpropanolamine (PPA).
Regulation
The World Anti-Doping Agency's list of prohibited substances (used for the Olympic Games among other athletic events) bars cathine in concentrations of over 5 micrograms per milliliter in urine. Cathine is a Schedule III drug under the Convention on Psychotropic Substances.[3] In the United States, it is classified as a Schedule IV controlled substance.[4]
In Australia, Cathine is officially a schedule 4 drug but is not available or approved for any use.

In Hong Kong, cathine is regulated under Schedule 1 of Hong Kong's Chapter 134 Dangerous Drugs Ordinance. Unlawful possession is punishable by severe fines and imprisonment.
