Highlights
•
The e-cigarettes contained and delivered mostly glycerin and/or PG and water.
•
Aerosol nicotine content was 85% lower than the cigarette smoke nicotine.
•
The levels of HPHCs in aerosol were consistent with the air blanks (<2 μg/puff).
•
Mainstream cigarette smoke HPHCs (∼3000 μg/puff) were 1500 times higher than e-cigarette HPHCs.
•
No significant contribution of tested HPHC classes was found for the e-cigarettes.
