Gore is free on $20,000 bail and scheduled to be arraigned Aug. 1 in Superior Court in Laguna Niguel. Prosecutors said he could be sentenced to a maximum of three years and eight months in prison if convicted on all counts.

In addition to Vicodin, officers found Xanax, Valium, Soma, and Adderall as well as a small amount of marijuana. A source tells People.com that police discovered 140 Vicodin pills on the former vice president's son as well as dozens of others.

The son of the former vice president and Democratic presidential nominee was previously arrested for marijuana possession in Bethesda, Maryland, in 2003, when he was a student at Harvard University. Gore completed substance abuse counseling to settle those charges.
