Presidential hopeful Mayor Pete Buttigieg called for the legalization of marijuana at a Democratic candidates forum hosted by AARP in Iowa on Saturday.

“When it comes to American drug policy, I don’t think anyone can look at it and say it’s looking well,” said the South Bend, Ind., mayor. But he had one caveat: “I don’t recommend smoking anything.”

Buttigieg was joined by candidates including Sen. Bernie Sanders (I-Vt.) and Montana Gov. Steve Bullock.
