You never know what's going to turn up! The obvious aside, the smell of poo and cannabis is distinctly different. There were a couple of youngsters quietly and contentedly puffing away in a shelter in my local park yesterday. We had taken our grandson to feed the squirrels but when the heavens opened and we dived into shelter. Phew, both of us commented on the pong, the two youngsters rather surprised that we recognised the distinctive niff. Perhaps we'll now see the Fuzz, on their knees, trying to fire up little piles of pooch poo rather than face the mirth of their colleagues.
