Aaron Rodgers spoke at a psychedelics conference in Denver on Wednesday.

During the conference, Rodgers made a pitch for such substances to be legalized.

"Is it not ironic that the things that actually expand your mind are illegal and the things that ... dumb you down have been legal for centuries?" Rodgers said. "We've got to change that. We've got to change that. It's through awareness and education."

The quarterback has been open about his use of ayahuasca in the latter stages of his career.
