I too have had this problem a couple of times.. just not as bad as you are describing yours. One because I am an asthmatic as well but the good news is that Marijuana has been proven to help most asthmatics and for personal experience I can say that it has, I haven't had to use my inhaler for over a year and a half! :thumbsup:

Now back to your topic.. Sometime last month I was sitting around with my friend in the living room watching t.v., before that we had smoked and everything was fine.. While watching t.v. I started to notice I was having trouble breathing (Doesn't help for the fact that I smoke cigarettes ) So what I did is I sat up straight and raised my arms above my head and put my arms across my head because when you do that it opens up your bronchial tubes and throat so there is more air flow. Another good thing to do while doing that is drink some high carbonated soda, the bubbles for some reason seem to help open up your chest passages so that more mucus get out and more air can get in. After I did all that I started breathing fine. Give that a try next time and keep your inhaler close by just in case anything is to happen. The second thing that happened in the same month everytime I'd smoke for some reason my nasal passages became very runny.. It came to me and I realized that the heat from the amount of smoke that a person inhales from marijuana opens up your nasal, throat, chest, and lungs (Which is why marijuana has been very useful for most asthmatic and allergenic people.. like myself) and I went along my way. For you there might have been a combination of that and allergies.. I hope this helps if not you might either want to stay away from the bud for a while or maybe consult a doctor about breathing/allergic problems and see if its a bodily change your going through. :jointsmile:
