Although ECs are not risk free, they are much less harmful than conventional tobacco smoking. The emerging clinical evidence suggests that ECs are unlikely to raise significant health concerns for the respiratory tract under normal conditions of use, even in smokers with preexisting lung disease. In particular, recent studies in COPD and chronic asthma suggest that substitution of conventional tobacco cigarettes for ECs can ameliorate subjective and objective disease-related outcomes and exacerbation rates as well as improving success in abstaining from smoking long term.
