31 August 2007: The grass is greener on the inside

Inmates at Japan's Abashiri Prison have something to look out for in their new prison exercise yard. There are marijuana shoots sprouting there.

Prison officials think soil brought in to make the exercise yard already contained marijuana seeds. So far they don't think prisoners have actually been cultivating the plants.

The prison does have a vegetable patch but, when questioned, the prison governor said, "We only grow potatoes and beans here."
