An 82-year-old American has written a heart-rending letter to his local newspaper claiming that e-cigarettes “saved his life". In a written letter to the Des Moines Register, Mr Hoover explained that he's quit completely after 65 years and says the impact on his health is huge. “The craving for a cigarette was gone, as was a hacking cough. My blood pressure is normal now without any pills, and I can breathe so much easier.” “Rather than trying to stop their use, it should be encouraged. It is just vapour, folks. Please use some common sense.” Mr Hoover added that he has nothing against smokers and revealed that since quitting he has managed to save just over $5000 (£3,500).
