The study examined 18 smokers with significant asthma who switched to electronic cigarettes. Ten of the patients switched completely and 8 became dual users (both smoking and using e-cigarettes). Among the dual users, the average cigarette consumption dropped from 22.4 to 3.9 cigarettes per day.

I'm sorry, but the words "gold," "silver," "orange," "red," "green" and other colors do not imply levels of harm. In fact, there are existing cigarettes on the market with the names "gold" or "silver" and these products are not accused of implying different levels of health risk. The only reason why these color names imply different risk level is that people know they are the replacement names for the former "light" or "mild" cigarettes.
