It's a legal maneuver.
That is not true, research has nothing to do with it in this case. It was about medical usefulness which is why other drugs are a lower class, because they have medical use. Though slowly, that is changing and while "weed" still isn't listed with medical usefulness, properties in the plant (that don't make you high) are starting to have value in treating a few different conditions that have only recently been found with a few patients.
