I've got two main units that I use, one is my Provari with a ZAP and the other is Altoids mod with a DCT. I use the Altoids at night while I'm in bed, but it was my main for a while (both day and night). I never had any health issues before and am a heavy vaper. About a week ago I noticed that I was getting a very sore throat at night and when I would wake up. The more I used my Altoids mod, the worse it would get. Then my Provari came in and I installed a new ZAP. I started using that significantly more than the Altoids and my throat got better almost instantly. Last night I went back to the Altoids mod and I woke up today unable to swallow and coughing up brownish green stuff. I'm convinced that it's my Altoids mod causing this. Well, not specifically the mod itself, but probably the DCT. Should I just throw away the tank and the juice that's in it or just change out the cartomizer inside it and save the juice?
