Comedian Russell Brand has told the BBC he predicts much of the world will have de-criminalised all drugs within the next two decades.
Brand, who is a former heroin addict, backs abstinence based recovery from addiction, rather than use of substitutes like Methodone.
But he told the BBC's Mark Easton he believed drug policy based on criminalising users was doomed and governments would adopt a new strategy to reflect that.
