Definitely you need to find some other way of taking in weed if you've had a collapsed lung recently. Although it doesn't appear to contribute to lung cancer in the same way cigarettes do, inhaled weed smoke is still a harsh pulmonary irritant that, in repeated studies, has been associated with higher rates of infection and bronchitis. Anyone who's recently had a pneumothorax needs to stay away not only from cigarette and weed smoke but also from dust, pollution, particulate matter, perfumes, pet dander--the works. You probably have already have been told that if you've had one collapsed lung, you're at high risk of having another. You certainly don't want to knowingly risk bringing on another by irritating your airways.

Wish I knew some good recipes to recommend, but I don't. You might try the recipes section of the boards and see what they say. Good luck!
