Young Buck - who is currently on probation - could possibly be sent back to prison for up to five years for reportedly faking a drug urine test. According to TMZ, Buck's probation officer claims that he came in for the piss test with a hidden bag of someone else's pee, and then used a tube to transfer the pee into the sample cup. Faking a court-ordered drug test is actually a felony offense, and Buck could face some serious jail time if he's convicted of the crime. Buck was released from prison back in 2013, and since then has rejoined 50 Cent in G-Unit, while also dropping his own solo music.
