The above photo shows a crowd assembled at the University of Colorado on April 20th, known affectionately to one and all as "Pot Day". And yes indeed, the billowing clouds are just what you think they are. I suppose that in this age of ever-grundgy news about the economy this is what's known as the student's anti-depressent non-prescription drug of choice. Small wonder, considering their chances of finding a decent job to pay off their astronomical student loan debts after they graduate. Hm-mmm, well of course I've never inhaled, so what do I know about it.
