Anyway, at one point they stated that early Christians are believed to have used cannabis in their anointing oil for ceremonies, etc. Though obviously the doco wasn't about ancient pot head Christians so they delved no deeper. However, I did today.
I googled a few things and found some a lot of articles and information on this subject. This one in particular seems to be a good and in depth read of this "cannabis christians" hypothesis and directly references sections of the bible that may suggest the use of cannabis, etc.
I'm sure most Christians would 'have faith' that this is complete nonsense and deny it outright... I guess we'll never know for sure, but apparently the biblical scholars that added to, removed from, and exaggerated or played down sections of the bible didn't think cannabis was a big deal prior to 1937. So why would we be surprised that a plant used so heavily in this time period for a myriad of different things, and that was grown in the same part of the world, was used by the people that existed their. Especially, by those wishing to have 'out of body' experiences that would undoubtedly make the user feel the 'presence of god' the same way hippies used to get smashed off it and feel at one with the trees and flowers. To me it would definitely have been an amazing recruiting device for the Christians.
Food for thought anyway.
