Denver 4/20 Rally

As the cannabis industry has expanded in Colorado, so to have the festivities surrounding the plant. This year's 4/20 Rally proved just that as national headliners Lil Wayne and Wiz Khalifa enjoyed the Denver ambiance complete with joints, blunts and enough weed smoke to get the surrounding suburbs high as a kite. We sent out photographer Kevin O'Donohue to the event to capture what it is truly like to be at one of the largest cannabis gatherings in the world.
