Effects of acute smoking on health-related biomarkers

Experiment details

This study will measure and compare biomarkers (biological indicators of factors related to health which can act as early predictors of disease) after a relatively heavy bout of smoking compared to a day of smoking abstinence.

This study requires you to attend the lab on two different days (one week apart).

On one day, you will attend the lab for a 15-min session between 12pm and 3pm. You will then leave the lab for 3 hours and smoke several cigarettes (we will let you know how many). You will then return to the lab for a 30-min session between 3pm and 6pm.

On the other day, you will abstain from smoking or using nicotine for at least 12 hours prior to your session and attend the lab for a 30-min session between 3pm and 6pm.

During the sessions, you would complete questionnaires, and have two biomarkers measured. To measure the first biomarker, we will use a device which uses light technology to read biomarker levels in your skin. To measure the second biomarker, a trained researcher will take a blood sample (5 ml) from a vein in your inner arm

You will be reimbursed £30 for your time and expenses.
