– It's a rare but not unheard of tragedy: succumbing to carbon monoxide poisoning in a vacation rental. Canadian police feared that situation was on the brink of repeating itself in Northern Bruce Peninsula, Ontario, early Saturday. They were called to a cottage by 10 vacationers, some of whom had started to mysteriously feel unwell. But testing soon showed there was no carbon monoxide issues. Then the real culprit emerged: a brownie cake made with pot that some of the group had partaken in. The Toronto Star reports no charges were filed. (Some Canadian cops recently allegedly partook in marijuana as well, with unfortunate results.)
