Professor David Hammond at the School of Public Health and Health Systems is conducting a 3 week study on smoking and vaping behaviors. The primary objective of the study is to examine the extent to which vaping/e-cigarette use reduces exposure to toxic chemicals, compared to smoking. We are currently recruiting adults in Toronto area 18 or older who use both cigarettes and e-cigarettes.

Sessions being held in downtown Toronto in February and March 2016.

Over the 3-week study period, participants will be asked to:

Abstain one week from cigarettes, one week from e-cigarettes and one week from both

Visit a lab 4 times in a downtown Toronto location (1 min each visit)

Complete a questionnaire and provide a urine and expired breath sample at each visit

Complete a brief online questionnaire (~2 min) every day for the duration of the study

Remuneration may be up to $295 for participation in the study.

All information is kept confidential. This study has received clearance through a University of Waterloo Research Ethics Committee. Funded through the Ontario Ministry of Health and Long-Term Care.
