Former NFL star Ricky Williams is featured in an upcoming SI Films production in which he discusses his experience with marijuana use and his support for legalization.

The exclusive film and accompanying exclusive longform special, written by SI’s Greg Bishop, will debut on SI.com on Wednesday, July 13.

The film, “Ricky Williams Takes the High Road,” is the first in-depth look at Williams’s life today, five years after his NFL career ended. He reflects on his clashes with the NFL drug testing program, his support of marijuana as a medicinal tool in the NFL and the anguish he felt as his image was tarnished because of his public support of the drug.

“It’s kind of true, but not the way that people see it, that I quit football to go smoke weed,” Williams says in the film.

The film also examines how Williams has become an entrepreneur in the marijuana industry. SI’s cameras followed Williams in several different locations, including the 2016 “Spannabis” World Cannabis Conference in Barcelona and the Williams family home in Austin, Texas.
