1) I sometimes feel like a lot of the discussion minimizes/understates the responsibility of the drug user. People are asking for trouble and taking a risk every time they use these products. Sometimes use can't be avoided or is the best course of action, but if you are responsible it is very rare that it turns into an addiction. The opioid problem is serious enough that everyone can get a fair share of blame (doctors, big pharma, dealers, law makers, families, etc.) while also recognizing nearly all of the addicts could have avoided the situation.
2) I think most of the solution could be obtained through greater/better education (children, legitimate users, illegal users, family, doctors, law makers).
3) Treatment should be provided, but should not reduce the responsibility of actions taken while under the influence (e.g., should not be used to reduce legal sentence).
4) Legalization with regulation seems like the best course of action as it would bring the people out of the shadows and make it easier to allocate more of the treatment cost to distributors/manufacturers/users.
