What is "camfetamine"

Camfetamine (N-methyl-3-phenyl-norbornan-2-amine) is a stimulant drug closely related to the appetite suppressant fencamfamine, being its N-methyl homologue. It has been sold as a designer drug following the banning of mephedrone and related substituted cathinone derivatives in many countries, and reportedly has slightly stronger stimulant effects than fencamfamine, but with correspondingly more severe side effects.
