so none of you all have any ideas on how exactly the GB damages your lungs? Like what exactly will happen if you hit the GB 8 times a day for 10 years? It's kind of difficult to make risk reward decisions when you don't know much about the risk. The only risk I know for certain is the temporary pain of taking huge hits, and if that's the only drawback then I will hit the GB for the rest of my life. But what I'm wondering, is if there is long term damage. Who cares about coughing fits and pain in the short term.
