Fresh water is potentially as harmful as salt water, depending on how you utilize it.

E-Cigs potentially saved my sons life. He grew up around smokers. I had no control over this. Now that he lives with me, I fully support the use of E-Cigs. He has almost stopped using E-Cigs and he has stopped smoking tar+tobacco cigarettes completely.

Traditional cigarettes for certain are carcinogens and there is no dispute they cause cancer and kill people.
