Asthma + Marijuana

I have a mild case of asthma it gets triggered when stressed, or cold climate. However I’m a long term marijuana user and during my time using I have no need to use my inhaler. Every time I stop smoking my asthma problem returns. I thought it was just coincidence but now that I’m working at a job that does drug test I find myself wheezing and it’s not only annoying but my diaphragm becomes sore. Last winter I didn’t need my inhaler due to using marijuana. I hate that they will fire me for having thc in my system because I think it’s an invasion of my personal life. I know it’s frowned upon with these companies because I’m a responsible user and would never go to work under the influence. Thought I’d share this here
