I haven't vaping for too long, maybe 4-5 months, but lately vaping has become really hard on my throat and lungs. I used to smoke a pack of cigarettes a day and cigarettes never irritated my throat. But when I vape now it almost always makes me choke and cough Andy lungs tighten up making it hard to breathe. It was not like this for the first few months and I have been using the same stuff. I thought it might be a bad batch of cartos but I have boges in all resistances from 3 different well known vendors, resurrectors, fusions, and I get the same pain on all of them. Tried going back to clearomizers, same thing. I find myself having to smoke a cigarette here and there to relieve myself from the irritation I get from vaping. I'm pretty sure it's not my juice either because I've been vaping bobas bounty from the start and it was not like this. I'm probably going to ask a doctor but I was just wondering if anyone here might know what's going on. I'm very sad because I really enjoyed it when it was good.
