Hallenges and Impacts of Tobacco Use on Employers

Challenges and Impacts of Tobacco Use on Employers

I am doing a general research project that investigates the challenges and impacts of tobacco use by employees. The research seeks to understand the perspectives of management personnel with regards to smoking employees.
I am going to use this paper to add to my current research project. I am also specifically interested in information related to the defense of smokers. From a survey I conducted at my work it seems that the majority of the population does not consider smokers as being less productive. I would like some information that supports this. I also need to have references to 3 scholarly journals.

Thanks.
