The mood was cautiously optimistic and the message was simple: Drug decriminalization saves lives. People who used or carried small quantities of illegal drugs in plain sight would no longer face arrest in British Columbia, the nexus of Canada’s opioid crisis, officials announced two years ago. So bold was the experiment, even in a province known for pioneering addiction policies, that its public health officer said she was in disbelief the day had actually come.

But it’s also the first big tech company to embrace of a class of health devices that haven’t yet gone fully mainstream. (Velazco, 7/10)
