Why he was so out of it: Xanax and Vicodin.

Those were the two drugs found in Tiger Woods’ system the night he was found asleep at the wheel, according to The Palm Beach Post, which obtained a new police report.

Xanax is used to treat anxiety, insomnia, and seizures; Vicodin is a powerful narcotic for severe pain.

The U.S. Food and Drug Administration has warned of “serious risks and deaths” from combining benzodiazepines such as Xanax, with addictive opioids like Vicodin.

Woods, who recently underwent back surgery, is currently in rehab at The Jupiter Medical Center for a painkiller addiction.

Radar Online reports that the golf pro is said to be doing this so he can keep 50/50 custody of his two kids with ex wife Elin Nordegren.

Woods was in rehab for a different reason back in 2010 -- sex addiction.
