Roseanne Barr -- Already a (Bong) Hit with Weed Advocacy Group

Roseanne Barr's soon-to-be failed run for President just got a little pick me up -- thanks to the biggest pro marijuana group around, which just announced its support for the comic-turned-politician.

The Executive Director of NORML (National Organization for Reform of Marijuana Laws) -- a guy named Allen St. Pierre -- tells TMZ, the group supports any candidate "who will adopt a pro-cannabis law reform plank as part of their political platform" ... especially Roseanne.

St. Pierre adds, "NORML welcomes Roseanne’s public support for ending a failed 74-year-old Cannabis Prohibition."

As we previously reported, Barr announced her intention to seek the highest office in the land and will go after the Green Party's nomination, campaigning to legalize marijuana.

Roseanne has a long history of being pro pot -- her classic sitcom even did an episode on the subject in the mid 90s. Roseanne also lives in two states (Hawaii and California) with progressive marijuana laws. Probably not a coincidence.

If only pot heads vote, she might just have a chance.
