I quit smoking and started vaping my cannabis 6 months ago. I never once had a respiratory problem from every day vaping, until 2 weeks ago when I caught a chest cold/throat bug from cold weather. Now Ive come to realize that I HAVE to take a break from it or Im never going to recover. The chest cold I got was unrelated to vaping, however vaping every day is preventing it from healing, and has caused bronchitis, persistent sore throat/coughing/wheezing that should have gone away by now, and a slight amount of blood in my phlegm every now and then. I should've been over the hacking by now but I'm not, likely due to vaping 2x a day since i came down with it. None of the vaping precautions Ive taken have helped (hot water filtration, special filters in my vapes, low temp short draws), none of that matters. Quitting the inhalation of vapor is the only thing that will fix it. I know if I stopped for a week the infection would disappear. But that's the problem with addiction, I just can't stop LOL. i love puffing on weed. Until now. The problem isnt going to resolve until I give my bronchial tubes a break so I gotta do what I gotta do. Oh well, perfect excuse for a tolerance break..
