Norcocaine is a minor metabolite of cocaine. It is the only confirmed pharmacologically active metabolite of cocaine,^[1] although salicylmethylecgonine is also speculated to be an active metabolite. The local anesthetic potential of norcocaine has been shown to be higher than that of cocaine,^[2]^[3] however cocaine continues to be more widely used. Norcocaine used for research purposes is typically synthesized from cocaine. Several methods for the synthesis have been described.^[4]^[5]
