The real deal on your lungs and weed?

[UTD Toker]

just because it doesn't cause cancer doesn't mean that it can't cause many of the same respiratory illnesses as tobacco smoke. (as weed smoke is much more dense)
Don't fall for the "WEED IS GOOD FOR U JUST BECAUSE IT CAN'T KILL U BULLSHIT.." your lungs aren't meant to be a chimney.[/B]

Have you ever inhaled smoke before? Because if you have inhaled any sort of smoke, ALL of that smoke has collected in your lungs therfore your lungs are black right?
Your lungs ROUTINLY clean themsleves or my previous statement would be true for all of us humans. You say respitory illnesses right? If I developed this what sort of long term effects would I be looking at? Just curious. Would you say my life say 30 years from now could be alot worse because I smoke a flower daily instead of drinking alcohal or smoking death sticks A.K.A. cigs? I feel relativly safe
