Subject area	Chemistry
More specific subject area	Forensics, Analytical Chemistry, Olfactometry
Type of data	Table
How data was acquired	Multidimensional gas chromatography (Agilent 6890), mass spectroscopy (Agilent 5973), olfactometry (MOCON, Round Rock, TX).
Data format	Analyzed mass spec using Automatic Mass Spectral Deconvolution and Identification System (AMDIS) (NIST, Gaithersburg, MD)
Experimental factors	Volatiles emitted from marijuana, cocaine, and heroin samples were collected on Carboxen/polydimethylsiloxane (PDMS) solid-phase microextraction (SPME) fiber at room temperature, static, for 1 h.
Experimental features	SPME fibers were thermally desorbed in a multidimensional gas chromatography-mass spectrometry-olfactometry (MDGC-MS-O) instrument, allowing for simultaneous chemical and sensory analysis. Surrogate scents for each drug were also analyzed as previously stated, and aromas were compared using calculated odor activity values (OAVs).
