So, a friend just got his stock clone a couple day back. Was with him today, wanted to see how his hit compared to mine. Just found out he was using the stock coils and hadn't cleaned the attie first. Well, I started to get really itchy in the chin and now it's most of my neck too. My throat is all itchy too. The liquid isn't the problem as he's using one that I always use, and have for a while now, with no reaction like this before. I just ordered silica to rebuild my own coil, and with never using silica before, i'm worried I have an allergy to it and am going to go have to buy something else to use for the wicks. Didn't know if it was because of something in the atomizer itself that got heated up because of not cleaning it first, or something in the stock coil that set it off. Does anyone know whats in the stock coil? Really needing some help here.
