Lane Garrison Reluctantly Leaves Rehab

Lane Garrison has been released from rehab, but not of his own wishes.

Lane Garrison has been released from rehab, but not of his own accord.

The actor was out for a jog in Los Angeles this morning despite having checked into the Tarzana Treatment Facility last week for what was supposed to be a five-month stay.

"He stayed at the facility for a couple of hours," a source close to Garrison tells E! News. "Because of the work he did as a substance-abuse program leader while he was incarcerated, they said he had already served his time in regards to rehabilitation so it would be redundant considering the work that he had already completed."

Garrison had hoped the stint in rehab would have completely satisfied his parole requirements, but now that is no longer the case.

"He's going to be on parole for a minimum of two years, maximum of three," says California Department of Corrections spokeswoman Terry Thornton.

Garrison was released from the prison after serving more than 18 months for vehicular manslaughter and drunk driving

"He's taking every day to assimilate back into normal life, day-to-day existence," says the source. "He appreciates everything so much, the sunshine, food is amazing."
