So I started vaping back in 2014, went from tanks to sub ohm to rebuilding and vaped 100% VG juice exclusively. Stopped in may of this year and went back to clove cigs for a while, just started vaping agian and I can't vape. It hurts my chest, I cough, it's very unpleasant. I can't touch my griffin 25, the only thing I can vape are my rda (5/6 wrap dual claptons .48-.50 ohms at 55-60w) and that still hurts if I drip too much. I have tried 100% pg, 100%vg, 0 nic, ( usually I vape 3mg), same results. I don't know what to do.
