What are some internal and external reasons to someone might use, or decide not to use, vaping?

1 it stinks
2 second hand smoke could cause cancer
3vaping is smoking you are inhaling smoke and that cause cancer.
4. you look dumb not cool blowing out judge clouds of smoke.
5.if you take a glass pipe put meth in it heat it up until it turns into a vapor cloud inhale it in to your lungs you are smoking meth not vaping meth what I'm saying is that vaping is smoking no matter how you look at it.

I know that one reason someone might decide to use vaping is so they can slowly get off of nicotine because I know one person in particular who used to smoke, then he used tobacco dip, now he’s vaping because he doesn’t want to give up tobacco now but he’s using a vape to slowly get himself off. Someone might not use vaping simply because it smells and they don’t want to become addicted and they just want their bodies to be healthy and tobacco free.
