We've had a MD speak on cannabis for AS at the Los Angeles Educ/Support Group, and I don't recall him saying that it was contraindicated. I do recall him saying that he believes it would be helpful and that some THC may also be needed to be effective. His slide deck is here: https://www.spondylitis.org/Portals...011%201622.pdf?ver=2018-10-15-161231-463
Hope that helps.
