There was an article in today's Sun dedicted to Salvia. See this similar online one: http://www.thesun.co.uk/sol/homepage/woman/health/health/2427928/Why-legal-highs-are-dangerous.html
Salvia Divinorum is a natural psychedelic drug, sometimes called an entheogenic, which means "creator of the God within". Currently it is legal, but there are moves afoot to make it Class A, backed by Rupert Murdoch's news empire, as you can see.
Like all drugs, Salvia should be respected and used with caution, but if taken properly it can have a marvelous, enlightening effect. As the comedian Bill Hicks once said: "It can make you realize that we're all one consciousness, life is just a dream and we're the imagination of ourselves." I doubt if the Elite want to crriminalize Salvia out of concern for our health! I think they're more concerned that if we evolve spiritually through the use of these drugs we could become ungovernable! This is why they banned LSD in the 60's.
