"What about Rastafarians? They claim it's their religious right to smoke ganja (marijuana)."

Don't see why not - never seen anyone starting on anyone after a smoke. Getting all religious people too stoned to preach sounds great to me.

Alchohol and nicotene are bigger killers than heroin and so is sugar, and they are all legal. Legalise the bloody lot and let people kill themselves with it if they want to.
