In the past, general statements have been made about how using electronic cigarettes could be beneficial to people who smoke combustible cigarettes. Details are now emerging about how specific groups of smokers can benefit from e-cigs. One such group is the people with chronic obstructive respiratory disease (COPD) and those with asthma. Speaking at Massey University in New Zealand, Professor Polosa revealed that his research has established that sufferers of those two conditions have had the adverse effects of smoking gradually reversed. He therefore finds it unacceptable that some health authorities still maintain a hostile stance towards electronic cigarettes. As more information filters in about vaping, it is becoming increasingly clear that nearly every smoker can have his or her health improve by switching to e-cigarettes.
