I have really bad asthma too, when i was younger i was hospitalised every other week because of it. I started hearing more about weed having medical properties, so i tried it out with some friends and it actually helps out with asthma. The natural chemicals from it actually loosen muscles, and it relaxes your throat. Im not a pothead and i only smoke like once a month but after i started smoking i haven't had an asthma attack, and it's been about 2 years now. Btw I'm 16
