So bummed to read about this! My husband and I don't smoke or ingest drugs, but when we visited Copenhagen, we for sure visited Christiania and walked around, and loved it a lot. I loved it so very much because I'm a true blue hippie. Even my husband, who I believe deep down is really a robot in human form, loved it. We thought about it afterwards, and we think it's because of the rules - no photography, no running, and there was a third rule that I forget. But those three rules made all the difference. People slowed down and we were all, I don't know, 'present' in a way that was unlike anywhere else.
