It could make sense. The cannabinoid receptor occurs naturally and for an evolutionary reason. Another interesting factoid: the cannabinoid signally system is retrograde: its information flow is OPPOSITE of all other neurotransmitters along specific neural paths. This alone makes prior bans on research into MJ tantamount to "Crimes Against Humanity". What I'd be interested in is how it might tie into testosterone pathways: one reality of T is that it enables you to mentally ignore the pain of exertion in a number of similar ways to cannabinoids.
