You can actually acutely treat opioid overdose (with antagonists) and so presumably the actual issue here is people use drugs alone in locations where nobody is going to check on them for something like an hour. There may be an education campaign there so that people prescribed painkillers know to never use them alone. Also, we probably need to invest in lifestyle education for preventing depression like we do for preventing obesity. Have campaigns asking people if they've had one pleasant conversation today. Force workplaces to give people a midday break where they are allowed to leave the facility in winter. Sensitize parents to symptoms of their child developing persistent anxiety or sadness like they are to the height/weight curves. (Also, develop ways of treating mild depression that aren't SSRIs -- light therapy, animals, caffeine, sleep deprivation, whatever, but a ton of people are refusing to seek help because they don't want meds that they see as having too many problematic side effects.)
