My boyfriend and I were discussing this last night. He is a non-smoker and non-vaper (though he doesn't have any problem with me being one). We talked about all the frozen meals in plastic containers we've nuked in the microwave and ate for the last few decades, and how vaping couldn't be any worse than that.
I do agree there is a lot of things in life that are horrible for us and we do them any way without thinking - heck breathing the air in a city like Los Angeles is likely as dangerous as vaping, certainly far more dangerous than second hand vapor.
I don't recommend a non-smoker vape. I smoked for 32 years of my life and was an addict, I wanted to quit when I was 27 and never could until vaping came around, not even when my health was at stake - so I worry about other people,
not that vaping is the same, (God forbid, dont think im saying that) I'd certainly wish someone vaping before smoking as it doesn't have that "addict" factor. It's just the mom in me.. it's not a no harm product, like spinach, for instance.
While vaping only has approximately 5%-20% of the harm of smoking (depending on who you talk to) that is still some harm. In 10 years, no ones died and no ones health has been seriously affected, but certain things like breathing problems may not show up for 20 or more years.
Heck I was working out hard two hours a day, everyday, when I had been smoking for 10 years, but by the time I hit 32 years of using cigarettes I couldn't make it to the mailbox without rest breaks due to my inability to breathe properly.
Of course, this is an incorrect correlation to make, because smoking is NOT vaping, but with vaping we don't know the problems yet that might show up with long term use. It's just not been around long enough to know for certain.
We know that smokers lungs will heal with a switch to vaping and we know there are serious health improvements when a smoker begins vaping, so we know it's FAR FAR BETTER than smoking, but to what degree it might be worse than doing nothing but breathing air is still just a bit of a mystery.
So the future, that's on you, and something you will be discovering on your own... we cant tell you much other than it's a far better option than smoking.
If your good with that, and feel informed and have decided its a chance your willing to take, then that's your decision as an informed adult..
