Methylecgonine cinnamate is a natural tropanealkaloid found within the coca plant. Its more common name, cinnamoylcocaine, reflects its close structural similarity to cocaine. It is said to be pharmacologically inactive. But some studies funded by anti-drug agencies imply that it is active when smoked. Methylecgonine cinnamate can dimerize to the truxillic acidderivativetruxilline.
