I've never understood people saying that smoking makes their asthma better-- it always made mine much worse. However, once I got my vap it got a lot easier. And I've actually read that that line about bongs being better for you isn't true, that it just cools the smoke but doesn't really filter out that much of the stuff before it hits your lungs. Don't know how true it is, but I do remember reading it.

All in all, I don't know about pipes vs. jays vs. bongs, but if your asthma is bad enough that you own a nebulizer, you should spend $100 to buy a vaporizer and stop fucking up your lungs with smoke.
