Back in the day when I was vaping, I believe, I had strep throat at the time, I even posted about it. The feeling was horrible. The nicotine actually felt like a burning sensation and I was only using 16mgs, I had to cut it to make it bearable. I remember talking to my doctor that I was using a electronic cigarette, he wasn't sure, but if anything it would make healing process longer. He told me the bacteria might have built up since I was using the same mouth piece for a while. So from that point on, I just either never re-use a mouthpiece or just boil them in hot water to clean them if I was low. My doctor's opinion might differ from yours, so can't really say. Heck, My doctor even told me he thought electronic cigarettes were a great alternative after I told him about it.
