Russell Brand has called on his fans to back a controversial reform of Britain's drug laws. The funnyman, a reformed heroin addict, met with Green Party Member of Parliament Caroline Lucas at the Houses of Parliament on Tuesday (21May13) and now he is urging his army of followers to join her campaign. Lucas has set up an online petition calling for research into the impact of the U.K.'s drug laws on addicts trying to kick their habit, and Brand posed for photos with her outside the parliament building to promote the cause. In a series of posts on Twitter.com, he writes, "Hello. Do you know anyone who has a drug problem? Have you seen anyone with one? Could we improve their treatment? Important! CarolineLucas wants the government to look at their daft drug policy sign this! "Need 100k signatures on this to cause aggro (upheaval) in parliament, please assist. Please sign this thing. It will help (us) all. It will take 90-100 seconds (depending on typing skills)... please stop celebrating gay marriage and get this signed." Last year (12), Brand gave evidence at a House of Commons Home Affairs Select Committee hearing into Britain's drug policy, urging lawmakers to decriminalise illicit substances and help addicts become useful members of society.
