A case is presented involving chocolate cannabinoid mimics which have been
utilized in court by the defendant's lawyer in order to clear the accused o
f smoking and dealing in marijuana after he was found positive for cannabis
in a routine urine immunoassay screening test. The argumentation in this c
ase was that the accused had supposedly eaten a massive amount of chocolate
which contained anandamide-related lipids. These lipids inhibit anandamide
hydrolysis in the brain, act as cannabinoid mimics and, according to the l
awyer, were the cause of the positive cannabinoid test. To investigate this
in detail, we synthesized N-oleoyl- and N-linoleoylethanolamide and spiked
these compounds together with N-arachidonoylethanolamide in urine for immu
nological investigations. None of the samples were found positive, indicati
ng that no cross-reactivity occurs with cannabinoids. As a result, the lawy
er's claim could be refuted and the accused was convicted.
