Methylecgonine cinnamate is a natural tropane alkaloid found within the coca plant.^[1] Its more common name, cinnamoylcocaine, reflects its close structural similarity to cocaine. It is said to be pharmacologically inactive.^[2] But some studies funded by anti-drug agencies imply that it is active when smoked. Furthermore, the discovery of differing impurity products yielding methylecgonine cinnamate in confiscated cocaine have led enforcing agencies to postulate that illicit manufacturers have changed their oxidation procedures when refining cocaine from a crude form.^[3] Methylecgonine cinnamate can dimerize to the truxillic acid derivative truxilline.^[2]
