Lamar Odom checked out of a rehab center Thursday about a day after seeking help for drug problems, sources tell PEOPLE.
The pro basketball player, 32, checked into the drug and alcohol center
on Wednesday morning and left Thursday afternoon with an assistant, according to two sources. Odom was later spotted in Los Angeles.
Odom's drug use
has led to trouble in his marriage to Khloé Kardashian Odom
– and last week he was arrested for DUI
– but his reality star wife has been focused on getting her husband help.
Odom has a history of drug issues. He violated
NBA drug policies twice in eight months back in 2001, and spoke in 2003 of his marijuana use.
