In an effort to track cannabis consumption more closely, the Canadian government has instructed Statistics Canada, Canada’s national statistical agency, to analyze sewage waste from about a quarter of Canada’s total 36 million inhabitants. In hopes to estimate how much cannabis Canadians consume, in total, through the sewage measurements.

Here’s the surprise: There is a mathematical formula which says if you tell me how big something is, I can tell you — with some variation, but not a lot — how long it will live.”
