Scott Disick -- Seeking Sobriety By Tripping His Face Off with Shamans

Scott Disick is fed up with traditional rehab treatments, so he's taking an all natural option -- as in sucking down hallucinogenic plants in the jungle ... under the supervision of a shaman, of course.

As we reported ... Scott checked into the Rythmia Life Advancement Center in Costa Rica, where we're told they use the African psychedelic shrub Iboga to send patients on a vision quest.

Hang with us ... it's about get even trippier. These "Iboga flights" are supposed to force users to examine their inner selves so they can learn what triggers their addictions. Sources connected to Scott tell us a shaman observes the entire trip, and the center says it's so effective ... it boasts a money back guarantee.

We're told Disick briefly visited the facility last month to research the place and was convinced Iboga could help him fight his alcohol demons.

Treatment can take several weeks, or as brief as one week -- but that would be one helluva trip ... we're guessing.
