I guess OP wants to start vaping for at least one of the reasons we all decided to start smoking.
Gotta admit, it is a half-wise decision.
My answer: 0mg
But I will say that if your reason for wanting to start vaping is because you just want to be cool, well, that's a poor reason and you will eventually see that when you get older. Vaping isn't healthy, it's just health
IER for those who could never kick the cigarette habit.
And it doesn't even get you high FS!
There are other things you can do to be cool. Like wearing these...
