Woody Harrelson On 'Colbert': 'Bullet For Adolf' Shameless Promotion Pads An Announcement About His Drug Use (VIDEO)

Woody Harrelson stopped by "The Colbert Report" last night on the circuit for his not-so-beloved new play "Bullet For Adolf." The off-Broadway comedy was co-written by Harrelson and his friend Frankie Hyman, a long-lost friend who came back into the picture after Harrelson publicized his search for him on "The Tonight Show."

Last night, Harrelson insisted he wasn't there to shamelessly promote, before unbuttoning his shirt and doing just that. It was funny! He also slipped in a revelation that'll have marijuana-themed publications everywhere scrambling for a new pot smoker of the month. That's right, y'all: Woody quit drugs. Looks like all those reviewers dismissing "Bullet For Adolf" as a stoner comedy were behind the times. Check out the full clip below.
