Detecting Cannabis Use on the Human Skin Surface via an Electronic Nose System

Detecting Cannabis Use on the Human Skin Surface via an Electronic Nose System

The most commonly used drug testing methods are based on the analysis of hair and urine using gas chromatography-mass spectrometry, liquid chromatography-mass spectrometry or immunoassay screening. These methods are time-consuming and partly expensive. One alternative method could be the application...
