Has anyone developed bronchitis or had difficulty recovering from it that they think could be caused by inhaling from any e-cigarette? I have been fighting bronchitis (3 rounds of anti-biotics) since the beginning of November. Every time I try to inhale any of my juices (some all VG and some 50/50 pg/vg) I start coughing uncontrollably. I've even tried one (even one with zero nicotine) but still cough and still having problems with this bronchitis. Since I love vaping (not had a cigarette in almost two years) I hate to think that I'll have to give it up.
