e-cigarettes introduce nicotine into your system. Nicotine causes artery constriction and can cause Coronary Disease or Peripheral Artery Disease (PAD) and the resulting clots and in extreme cases; heart attack (AMI) and/or distal limb amputation (the portion of the leg below the knee.)

You won't die of cancer from smoke carcinogens but there are other nicotine related dangers.

Do you really need nicotine? I quit cigarettes, it sucked and still does.
