Pot destroys lung function when smoked.
NOT TRUE. I smoked it for years in my early life. I am 63 and just had an oxygen saturation test measuring 97%. I would say that trumps your OPINION.
As previously stated, I would do it now, but for the WOD penalties. I did smoke an Acid cigar last night, and washed it down with two fingers of Glenmorangie 18!
