As expected, higher prices affected all smokers' purchase choices: 18-24-year-olds chose e-cigarettes 34.4 percent of the time when they cost $3, but only 8 percent of the time when they cost $9. Older smokers selected $3 e-cigarettes 18.3 percent of the time but at $9 only 3.2 percent of the time.
This study does show how high taxation would affect smokers' likelihood to make the switch, particularly younger smokers. I suspect the percentages would be even more drastic for people living near the poverty level.
For all the pleasure I've had vaping every imaginable flavor, if the choices were limited flavorings, high taxes or restrictions on equipment and liquid like the FDA is proposing, restricting flavors would be the one that would be best to help smokers continue to make the switch. As I'm most concerned with keeping vaping available to help existing and future smokers, it sounds better than the direction local, state and federal regulations are headed.
If the "it's about the children" bandwagon was legitimate and not just a tactic, this study would have more value. Unfortunately, we know it was never about the children in the first place.
