A first at the Oregon State fair.

FOX's Lilian Woo reports:

Prize winning marijuana plants will be a new attraction this year at the fair, which features classics like the pie eating contest and one for best beard and mustache.

Now this summer the Oregon State fair will also hand out ribbons for marijuana plants. They'll be on display at the annual event which kicks off August 26.

Fair officials saying its a nod to the newly legal status in Oregon of the crop. The nine plants will be on view in a greenhouse monitored by a security guard. No samples and no one under 21 allowed.
