Investigating exposure to toxicants from smoking and vaping

Overview

We are trying to identify what chemicals are found in the urine of people with mental health problems who smoke tobacco, use e-cigarettes, or do not smoke or vape. 

If you only smoke, only vape or do not smoke or vape, we would like to see you twice, 6-months apart. If you smoke and vape, we would like to see you once a month for 6 months.

To begin we will ask you to complete a questionnaire about how much you smoke or vape. We will then ask you to provide a urine sample so we can test it for chemicals that are found in people who smoke tobacco cigarettes. We will also ask for an extra sample of blood during your routine blood tests.

We would also like to have a quick phone conversation with you in 3 months after we first meet to ask about how much you are smoking or vaping.

Are you interested in taking part in this study?
