Sorry mate. Don't smoke weed.
But, there's always Christiania, but you'll have to be really careful out there because it's usually under pretty strict and thorough surveillance by the police, because the government has decided to shut it down. A Process that they're having lots of trouble with cause the people are against it. But you can always get weed there. I can't enlighten you qualitywise though... I know it's sold on the streets as well, but when you're on unfamiliar territory i would advice against buying on the street. But that's your call in the end mate...
Well. let me help Jesper out here.
In Christiania - and Copenhagen in general - it's almost exclusively hashish being sold. The quality is - for english standards - quite high, and the price fair. You might find it a bit expensive though, due to the low value of the pound. But hey, that goes for everything I guess. 1 gram of very high quality can be bought for around 60-70 kroner = 7-8 pounds.
I've just returned from Amsterdam, and I still think the Copenhagen selection comes out on top.
Christiania is - if you don't know any locals - the place to go. Just ask anybody when you get there. From the main station, you can take the bus 2A to Christianshavns Torv. From there it's a 5 minute walk to Christiania.
If you insist on getting weed, I can help you out, and it'll cost you no more than a Guinness. Send me a PM.
