I read comments from former 2-3 pad smokers saying 18-24mg/ml was to strong for them. I have tried both those strengths and feel nothing at all. I was a 2-3 pad smoker myself. I always took quick drags never holding the smoke in long and I use my pv the same way. I ordered some 30mg and 36mg it's on the way. Does this sound safe considering my vapping style? I just spoke to another juice vender that said they don't go over 24mg because it's dangerous. I tried changing my inhale style, but after 25 years of smoking it's hard to do.
