Of the many roles Pat Robertson has assumed over his five-decade-long career as an evangelical leader - including presidential candidate and provocative voice of the right wing - his newest guise may perhaps surprise his followers the most: marijuana legalization advocate.

"I've never used marijuana and I don't intend to, but it's just one of those things that I think: this war on drugs just hasn't succeeded."
