Portugal. They’ve essentially been doing this for years.

Drugs are decriminalised and in themselves legal.

It’s still technically a crime to use them but generally you are treated as a patient with addiction. Not a criminal.

There’s still a massive body of criminal law around supplying, and producing them.

So they are not dismantling controls on drugs but targeting the issues drugs cause instead of criminalising users needlessly.

Not perfect there but certainly lessons to be learnt.
