Why? Leaglization of the mind-altering addictive drug alcohol has proved to work much better than banning it.
I do have some thoughts on what I believe is a better approach, but since they would never be put into practice, it's pointless to talk about them.
I'd like to hear them. :)
I'll give you the condensed version as I am heading out to the store shortly.
Basically, we build what amount to dormitories and we house the addicts. Yep, lots of housing. These people are supervised and *confined* to the premises. They are offered counseling and rehab services and will be expected to perform some basic tasks required to help keep everything going. Cleaning, laundry, gardening and such. Cafeteria style eating arrangements for all.
Rehab and counseling are offered, not forced. Anyone that wants can refuse and will be allowed to sit in their room and given the drugs that they want (in non fatal doses). They will still be allowed to use the cafeteria, not gonna starve them. When they die, it's off to Potter's Field for them. Turnover should be fairly brisk.
Regarding this business of repeatedly reviving Fentanyl ODs, they would be informed that they are limited to XX OD revivals and when that is met, they will not be revived. Again, off to Potter's Field - again, brisk turnover.
That's the nuts and bolts. Obviously a lot of detail and fine tuning would be required. We get them off the streets and out of normal society. Those that want help receive it. Those that don't are not forced. They will solve their own problems soon enough.
Because help will be freely available for those who want it and are motivated, I don't see letting those that don't want to be helped to drug themselves to death as immoral. Let them decide.
