I have asthma... Asthma flare-ups have gotten more frequent since I've started smoking pot, like, wheezing after walking up a great big hill, but it's not a big deal. A cup of tea or something with caffine with calm it down right away.

And if I wheeze when I'm smoking, I just chill for a minute, then take smaller hits. Or vape with a lightbulb. It's totally managable, and the little bit of wheezing that it causes nowhere near outweighs the joys of smoking pot. I still weight-train, row, canoe, play DDR...all those good things. You'll be okay.
