While cigarette smokers may say that the smoking habit helps them relieve stress, compelling medical and scientific evidence points to nicotine dependency as a cause of psychological stress, and those who do smoke consistently report higher levels of stress than their nonsmoking counterparts. 

If you want freedom from this habit or need to quit due to health concerns, you can accomplish this goal.  I suggest finding alternate methods of stress management through trainings and "healthy" products.  I also highly recommend quitsmokingstop.com

This is a website run by a friend of mine who has dedicated his life to helping others "kick the habit".  You will find everything you ever wanted to know about smoking and how to stop !
