Go to West London, try near south bank, ask skaters, do not talk to chavs, people dressed in tracksuits and new era hats. They will rip you off, sell you sprayed weed. Inspect anything before you buy it. I've lived here for time and the connections vary, sometimes it's all great and other times there's a drought or it's bollox stuff. I'm glad i'm chillin with my QB of good quality hash. Ask people you think you can trust. Ask for skunk. It is relatively easy to find if you keep searching. I wish you luck. I dunno bout the red light district, i think that's soho. I wouldn't waste my time coming over here, go to the netherlands instead.
