New to vaping, just got a SMOK mag mod vape, and have been using CBD with it. After about a week an a half my throat started hurting, I stopped vaping 3 or so days until throat felt better.I changed the coils just to be safe and after 2 days of vaping my throat hurts again! What am i doing wrong ? I'm taking 2.5 sec draws inhaling direct to lung with low watt settings or is it the CBD oil ?
