Weed Good for Lungs?

After reading numerous scholarly journals and watching countless interviews of medical professionals, I have no regrets putting posts about cannabis, magic mushrooms, MDMA, or any other non-addictive drug that may have positive effects on the health or simply on overall quality of life.  I am on-board and a full supporter of legalization for consumption.  Not for medical use.  And not with restrictions on an individual's right to grow and distribute.  I want us to have complete freedom on this issue.  Sometimes this topic spills over into spirituality, but this link (almost a year old now) definitely fits in here.
