I'm sorry, but comparing what to what?
I am very young, about to turn 19. Smoked from 13-18, which wasn't that long.
I just think that until the hard evidence comes out that vaping truely is not harmful to our health that it is best if we, as a community, pass these off as a safer alternative to those looking to get off tobacco. I personally see it to be very possible that vaping be not harmful, just waiting on the long-term scientific research to be done.
The long term scientific data will be in by the time you're 39 or older. I'm 65 and although my kids want me to live forever, I'll consider myself lucky to be around at 85.
If you want "healthy" then you have to quit cold turkey, I've tried it and it doesn't work either at least for me. So I'll keep on using a "healthier" alternative to cigarettes.
There's no guarantees in life. I've had people in my family and group of friends who were health nuts, never smoked, exercised religiously, ate "right," and one of them died of a massive heart attack and the other died of cancer. One thing is for sure, we're all going to die sooner or later.
