I have stage 1 COPD and currently vape 6mg in my Pharaoh mini RTA. I tried the Ares RTA and vaped 12mg and hated it, switched to the Wasp Nano RDTA and found it too harsh on my lungs. So now I'm back to my Pharaoh. I'm constantly clearing my throat and coughing. I'm at a loss. I want to continue vaping. Could a pod system be easier on my lungs? I'm roughly going through 6-8 tanks a day. But I've vaped 4 tanks a day in the past and still had the throat and lung agitation. Should I just give up vaping altogether and go on nicotine gum? I'd really prefer to keep vaping.
