 In mice, cathinone produces the same types of nervous pacing or repetitive scratching behaviours associated with amphetamines.The effects of cathinone peak after 15 to 30 minutes, with nearly 98% of the substance metabolised into norephedrine by the liver.Cathine is somewhat less understood, being believed to act upon the adrenergic receptors causing the release of epinephrine and norepinephrine.
