I just recently started smoking the green, and let's just say I love it. But my only problem is I have asthma and I find that most methods of smoking irritate my lungs and throat. I think it's mostly the heat of the smoke, and maybe some ash or impurities. I found that the only method so far that doesn't make me cough is a bong. What are some other methods to try? I'm considering buying a small bong or bubbler to tale with me when I smoke, but how harsh is a bubbler? I've never used one. Thanks!
