There are millions more people addicted to nicotine that never would have been absent vaping. We were winning the war, thanks to sound policy moves. E-cigarettes might be an okay solution for helping smokers to quit smoking. But the easy availability and marketing has led to an absolute and total epidemic, and no one seems to care.
People get incredibly defensive about this. I've been met with outright denial that it was even a possibility. Go back through my commenting history even on HN, and you'll see people telling me kids will never start vaping because "well, it's not cool." You get told well, look at all these people that quit smoking. That's great! But I don't see why it was necessary to trade smoking cessation among older cohorts for vaping addiction in teenagers. We have a massive public policy failure on our hands, and it's not getting better.
The only thing we can say is well, at least the public health crisis won't be as bad as what we had with cigarettes. Okay. But we didn't have to have one at all. E-cig companies (many of which are actually owned by the old tobacco giants) have successfully ensnared a whole new generation of addicts.
