Hey guys, I just wanted to put this out there and see if any of you had some knowledge you could share with me as far as vapor and carcinogens. Any and all info is appreciated! For a little background, I lost my leg to cancer 3 years ago. The most likely place for the cancer to recur was my lungs. Needless to say I have been pretty careful about how I treat my lungs since that time. I moved to edibles and vaping and cut out smoking altogether. After being cancer free for 3 years, a few months ago we found a cancer nodule in my lungs. I had it immediately removed and am doing fine, but was curious to know if anyone has any research about cannabis vapor and how it affects the lungs. My herbalizer arrives today and I am really excited about it, but I also want to make sure that I am not causing myself more harm than good by using it. To be clear, this isn't lung cancer, it is cancer that has now metastasized to my lungs (or at least one nodule has popped up and been removed). Any other cancer survivors out there have any knowledge on the subject? Thanks and stay well!
