Thanks for the info, and im not smoking moldy weed, just a legitimate question about my health as far as im concerned. The area i am in due to the climate is a haven in peoples garages for powder mildew, i cant inspect every single thing going into my lungs ie. other peoples weed, so i was just wondering if there was any alternative to improve the quality of smoke entering my lungs. Thank you again stinkyattic, your posts are extremely informative
