How would you like the drug regulation system to work?

I haven't researched it super-thoroughly -- but I've heard that Portugal has decriminalized all drugs and is now spending 1/4 on rehab what it had been spending on enforcement. That seems like the way to go to me. A friend told me that now the Netherlands is doing the same thing. I know it sounds pretty chancy, but I just sort of naturally like the idea. I think it's the way to go. I think this method would protect personal liberty the most, which is a big issue with me.
