Research Abstract

We developed an analytical procedure using gas chromatograph-isotope ratio mass spectrometer which allows acquisition of compound specific stable-isotopic compositions of herbal cannabis, marijuana, and evaluated the stable-isotopic compositions for distinguishing or linking marijuana samples. The sets of marijuana samples from different origin were able to discriminate using stable-isotopic compositions of the principal constituents of cannabis.
