But the self-proclaimed "hockey mom" had some youthful indiscretions.
Palin has said she smoked marijuana but didn't enjoy it and doesn't smoke anymore.
"I can't claim a Bill Clinton and say that I never inhaled,” she told the Anchorage Daily News in 2006.
At the time, marijuana was legal under Alaska's liberal drug laws.
A 1975 Alaska Supreme Court decision allowed adults to possess small amounts of marijuana for personal use. In June 2006, a law signed by then-Republican Gov. Frank Murkowski re-criminalized the drug. The American Civil Liberties Union later sued the state, alleging that the law violates Alaskans' state constitutional right to privacy.
Palin has said she doesn't support legalizing the drug, fearing the message it would send to her five children.
