Hi,
I might be able to bring some information to the table...It is the hops in beer that is priming the neuro-receptors of the body's own endocannabinoid system. More specifically the terpenes in the hops are very powerful and they prepare more neuro-receptors to uptake more cannabinoids like THC and CBD. This is called the "entourage" effect and there are other foods that have just as powerful terpenes, like: chamomile, basil, mango and lemongrass. In addition, both alcohol and THC act as vasodialators, expanding our blood vessels and increasing the blood's ability to circulate. This is part of the reason we are prone to blood shot eyes when we consume cannabis or drink alcohol.
Greatly enjoyed your post. :)
