Hi fellow vapers, I am new to vaping and am coming from nothing. My wife smokes when she drinks, so here and there I used to buy a Blu E-cig and dabble with that if we had a night on the town. At one point I acquired a small E-go pen and vaped for a few months. This small, 15 watt device never really gave me any troubles with breathing. However, I just bought myself a Smok Osub mini and have been vaping for about a month. I direct inhale, and have worked my tolerance up to 40W with 80/20 liquid. About 2 weeks after I started, I felt some nasal congestion, and eventually some chest congestion. This went on for about a week or so, and got to the point where I was coughing a ton, and was full of mucus. I stopped vaping for 4 days and I seem to be clearing up. There was a cold bug going around my house, so I thought that is all it was, but now I question if this was from vaping itself. Has anyone else had this happen?
