And here we have another victim of the US' failed war on drugs: Chief Keef is being sent to court-ordered rehab after failing three random drug tests for pot.

Currently in a Cook Country lockup, a Chicago judge made the decision. All the hubbub stems from a speeding ticket, when cops clocked him doing 110 mph in a 55 zone back in May.

This is the 18-year-old rapper's second F on a drug test -- just last month he got 20 days in jail, but was released 11 days early due to jail overcrowding.

How much is this song and dance costing Chicago taxpayers? Tens of thousands of dollars. It begs the question: why not let the kid just smoke some weed?
