- Cannabis products, like those containing THC and CBD, are popular for their health benefits, but often mislabel their cannabinoid content, leading to consumer confusion.* -

Microextraction by packed sorbent (MEPS) was used to pre-concentrate the analytes, which were detected by gas chromatography-mass spectrometry.
