Everyone likes to quote the statistic about ecig usage among teens 'exploding' but has anyone ever bothered to do a study on the correlation between increased ecig usage, and decreased combustible cigarette usage among teens? I would not be at all surprised to find out that they largely cancel each other out.
It's not ideal, but at the very least the net result would be kids having a 'healthier' bad habit which is an improvement in my eyes.
