The only two things that come to mind was a festival of 10,000+ that had a bar with drugs for sale, plain as day with a sign that said "LSD - $, Cocaine - $, Hash - $, MDMA - $" with the prices. Was awesome to see that kind of freedom, though I heard they had to bribe police.
The other was a head shop, that also functioned as a "smart shop", where you could buy all kinds of weed, mushrooms, acid, etc, on display in the glass. There was an off duty uniformed cop with a sawed off shotgun guarding it.
