I'm asthmatic, but I don't consume whole superhots. I'll eat a sliver here and there, or in a meal, or a taste of powder but it's not because of the asthma really. I take non-steroidal albuterol every day which works pretty well for me. I just haven't gotten my heat tolerance up very far this year. About a week ago, while grinding dried pods without a respirator, I inhaled a small cloud of Black Naga powder. My lungs became inflammed and I had a hard time breathing for about 6 hours, but it went away by the next morning. I'm pretty sure this would've happenned to anyone, regardless of any prior condition. If you feel like you've got a good grip on your asthma, I'd suggest starting with a small piece of 1mil+ SHU peppers and working your way up gradually to whatever you're comfortable with. Powders are a good way to step it up because you can start of with just a few specks and keep going from there.
