So I ordered my first rda about a month or so ago and don't regret it one bit. Though I am having one problem, the throat hit. I have used up to 50/50 Vg/PG 26mg nicotine on my rda and will get a very harsh throat hit but no long term effects. Recently I have been buying 100% PG 12mg nicotine and the throat hit is not all that bad but woke up the other morning with a very sore Throat and some blood in my saliva. since then I have been giving the myself a break. Would this be from the 100 PG juice that I am using? If so I am tossing it in the trash can and buying some more 50/50.
