What drug did Jeff Hardy use?

Yes Jeff Hardy has an addiction to Marijuana ( AKA Weed) and is currently breaking the habit. He has gone to Rehab about 3 times. Jeff started back in September in 2007. He later went to rehab and returned. Jeff then took it about 2 weeks before Wrestlemania 24, where he was actually schedualed to win the Money In The Bank. Jeff's most recent taking of the drug was of January 2009, but was then caught by his brother Matt, in which Jeff completely broke the habit due to some strong Words from his brother. Jeff is currently clean, and to be honest, I hope that's how it stays.
