The identification of synthetic cannabinoids surface coated on herbal substrates using solid-state nuclear magnetic resonance spectroscopy.

Solid-state C and F NMR spectroscopy offers a non-destructive, highly selective protocol for the identification of forensically relevant synthetic cannabinoids on herbal substrates. Using this technique, well resolved C spectra were obtained that readily enabled structural identification; in some instances complemented by F spectral data. The approach described has potential for related applications such as the direct detection of pesticides on plants.
