The one year study found that from the 18 asthma suffers who made the switch to ecigarettes and were also dual users of ecigarettes and traditional cigarettes there was a significant improvements in small airway obstruction.
From the 8 dual users the average consumption of traditional cigarettes dropped from 22.4 to 3.9 a day. Dr Polosa stated that in those studied the outcome was “substantially reducing number of cigarettes smoked per day and exposure to their hazardous toxicants, e-cigs may not only improve asthma symptoms and pulmonary function but may also confer an overall health advantage in smokers with asthma. Therefore, e-cig use in asthmatic smokers unable or unwilling to quit should be exploited as a safer alternative approach to harm-reversal (i.e., specific reversal of asthma-related outcomes) and, in general, to harm-reduction (i.e., overall reduction of smoke-related diseases”.
This study is the first of its type and of course more are still needed to get further results on how making the switch can affects peoples lives.
