Yeah that's why speed is popular because its cheap and lasts long. Nasty stuff imo. Coke is typically only consumed by the wealthy in Warsaw and rich chicks with bulemia. Weed/hash is more for teens and the wiggers. Back in the day you could drive through a rural village, walk into some farm and chances are there's a few plants just chillin'. Polish farmers use to use the seeds as a feed.
the police do stop people, do search, and the legal environment in PL is not a good one.
I've never been searched coming out of the club. In fact now that I think about it I don't think I've even seen any cops anywhere near the clubs after midnight. I would highly recommend avoiding any drunken ukranian guys - they love to pick fights. Fighting outside of the club is rather common in wroclaw as people are leaving the clubs... and it's sometimes even encouraged by the girls lol
Just put your stuff where your cell phone battery would go. In all my years of going to raves, clubs, etc. I've never had my cell phone taken apart and searched by security. Usually they're looking for weapons anyway, not drugs. Kind of like TSA at the airports in the US.
Banana is the place i usually go to. If your a foreigner and look half decent you'll have girls asking you to dance instead of the other way around. No bs.
