Former talk show host and longtime medical marijuana advocate, Montel Williams, detained for pot possession at the Frankfurt airport in Germany...
Montel's rep tells us he was traveling through the Frankfurt airport with his wife early Friday, and got stopped by customs agents. They discovered marijuana in his carry-on which Montel uses to help treat his MS and detained him for questioning.
We're told Montel informed cops the pot was only medication and called his team back in the U.S. to send over proof of his prescription.
Williams' rep says once Montel presented the proof, the German authorities were cool with everything and let him go. He was held for less than an hour.
