There was actually a study about this released the other day.
Marijuana users can breathe easier: Smoking joints didn’t hurt lung function in 20-year study
I agree that environmental factors are a huge part. Also, I agree that any evidence I have of negative effects of BHO on the lungs is anecdotal reports from users, not from a study.
Some COPD patients like ear wax as an expectorant. I find that it makes me wheezy after a week or 2. Not everyone's lungs will react the same way to even the same exact product. You just have to experiment and find what works best for your specific situation.
