So is anandamide a name for a type of cannabinoid? I actaully read something about this a couple weeks ago, suggesting that cannabinoid receptor stimulation was more predominantly responsible for the runners high, as opposed to endorphines. It's cool to see another journal article suggesting the same. Though I imagine endorphines still play some role. This has also made me wonder, with a tokers high cannabinoid tolerance, wouldn't we be considerably less susceptable to the runners high?
