For instance, Portugal had a crisis 25 years ago with sky high number of drug related deaths, HIV infections etc. The solution was decriminalization and education, e.g. about sharing syringes. And it worked, they went from the worst I drug related deaths to best. Heroin is still bad for you and I guess people still use drugs, but at least the outcome is not catastrophic anymore.
So yes, I do think education cures a lot of problems.
