Some would say the puke part is part of the cleansing, more spiritual than physical. Comparing shrooms to alcohol is very unfair. One is a spiritual plant, one is poison.
Portugal is certainly one step in the right direction. I lived and worked there for three months and it's all very relaxed. Cops don't really care about people rolling joints or even doing lines of coke in public if there's a party (and if you are in Portugal, there will be). Quietly puffing a joint while walking down the street in the middle of the day is cool as well. I actually never saw the cops interfere with anything while I was there, even though there are cops everywhere. There is one more thing about Portugal and drugs that needs to be said though: never, ever buy anything being offered to you. And you will be offered drugs ten times a day while just walking down the street. It's all fake, they're just out to scam you and steal your stuff, and they're pretty good at it. Just say no, thank you and go ask the cool kids hanging out in Martim Moniz instead. Good hash, coke and heroin is easily obtainable and cheap.
Sweden is fucked up as well, and I'd expect Norway to be the same or worse. Sweden jumped on the war on drugs-train head-first and tried to do it better than the US. And I don't think they got the other memo about the whole approach being a complete failure. It doesn't help that the famous German bitch we insist on keeping with "food" and "shelter" is running her own No Drugs-campaign with religious overtones. Or that the politicians in charge believe that overdosing on Cannabis is like overdosing on Heroin.
And it get's worse. Because your not really tripping but rather fighting poisoning, it effectively cuts the connection to the better part of who you are. If it wasn't for alcohol, a lot of the trouble we see in society simply wouldn't exist.
