A large crowd of drugs campaigners gathered in Hyde Park in London at Sunday’s ‘420 Day Celebration’ to hear speeches in support of decriminalizing cannabis and to smoke the Class B drug. The cloud of smoke was so thick, and rose so fast, scheduled airliners were ordered to divert from their usual flight path! Unfortunately the news came too late for pilot of BA 6749, who ended up doing a loop-the-loop at 22-thousand feet, causing several passengers to upchuck. Huh, and they say cannabis is harmless!?
