.. is marijuana?

Scientists at the National Centre for Scientific Research in France, have found that cannabidiol (CBD), a non-psychoactive ingredient in cannabis, may prevent the development of prion diseases, the most well-known being "mad cow disease" or BSE (bovine spongiforme enzephalopathy).

It is believed that the BSE may be transmitted to humans, where it is known as Creutzfeldt-Jakob disease. The condition is often fatal and spreads easily.

"The latest study adds to the huge amount of scientific evidence supporting the medicinal use of cannabis," said NORML spokesperson Chris Fowlie.

"Green MP Metiria Turei's bill to allow the medicinal use of cannabis should be supported by any MP with a clear head. Unfortunately most politicians act like mad cows whenever cannabis is mentioned."

So, if you're eating steak, but are concerned about all of those pesky prions...make sure you bring out your old gravity bong.
