I was bored last night and ended up watching this documentary about legal highs. Aparently its big business here in the UK, even though ive never really heard of it. You can literally walk down Camden high street in london and buy legal versions of weed, pills and ecstasy and cocaine, its crazy, and perfectly legal! The stuff is meant to have the same effects as the illegal stuff aswell.
