Would meth lung damage be worse than say cigarette damage?
Yea, that's what Mr Scootin was referring to and is why we can't answer this with any certainty.
Pure methamphetamine that is vaporized perfectly probably isn't all that bad for your lungs when compared to cigarettes.
But in reality, people are vaporizing methamphetamine with various cuts and left over products from manufacturer. It's impossible to account for all those variables especially considering some pyrolysis is likely occuring during vaporization.
That could vary based on so many unknown factors that I'm honestly not sure it's possible to answer that question with any degree of accuracy.
