In this video blog I discuss a new study from Columbia University that looked at CT scans of over 1,700 persons and found that those that grew up with smokers had more "emphysema-like" holes in their lung tissue. Why is smoking so addictive? What are you exposed to when you light up? Why can't you stop. I answer these and more in this video.
