Comment on: Are e-cigarettes a safer alternative to smoking?
Anonymous -- It was great to read your listing. Unfortunately, the debate around Electronic Cigarettes has turned into a comparison of ECigarettes vs Tobacco Cigarettes. It's likely due to the use of the word Alternative. ECigarettes are not at all like Traditional Tobacco Cigarettes other then Look, Feel and Nicotine; without carcinogens and tar.
I will cite the FDA; Nicotine causes the addiction not cancer. The tar and carbon cause the Cancer.
Where I will slightly disagree is, Nicotine does restrict the Arteries, potential for heart disease, and increase blood pressure / heart rate.
I couldn't agree more with your stance though.
