Nornicotine in Smokeless Tobacco as a Precursor for Carcinogen Exposure
Our goal in this study is to investigate the extent of endogenous nitrosation of nornicotine in smokeless tobacco users as a function of nornicotine content in smokeless products. This study will lead to an understanding of the endogenous formation of NNN from nornicotine in humans, and will also investigate the effect of the reduction of nornicotine content in smokeless tobacco on the extent of endogenous NNN formation. The knowledge gained in this study will lead to the development of recommendations for the regulation, or potentially elimination, of nornicotine in smokeless tobacco products in order to minimize exposure to NNN in the users of these products.

Effect of Passive Smoking on Functional Capacity, Cognition and Academic Performance in Primary School Children
This is an observational study that aims to understand the effects of passive smoking (secondhand smoke exposure) on children's health and development. The main question the study seeks to answer is: How does exposure to secondhand smoke affect the physical fitness, cognitive abilities, and academic performance of primary school children? The study will compare two groups of children aged 6-11 years: one group exposed to secondhand smoke at home (due to parents or caregivers who smoke) and another group not exposed to secondhand smoke. The children's physical capacity, cognitive skills, and school performance will be assessed through various tests. The goal of the study is to provide valuable insights into how secondhand smoke may negatively impact children, helping families, schools, and healthcare providers understand the risks and promote healthier, smoke-free environments for children.
