The title was basically the point of this post. Yes it does. I started using my first e-cig about five days ago and it hurt a little at first and then got better and now it's just awful. I'm using the liquid that came with my 901-tobacco flavored high nicotine. I was wondering if this is normal at first or if it will always irritate my throat? It's pretty harsh when I hit it. Then, could it just be the crappy liquid e-puffer sent me with my over priced starter kit? I have ordered (LAST WEEK!) but not yet recieved two bottles of liquid from Johnson's Creek, is it possible I'll feel better using a different liquid? Or is it possible it's the PG in the liquid? I don't want to have to stop this new habit! Thanks if anyone can help me.
