The alcohol found in alcoholic beverages is ethyl alcohol (ethanol).
Alcohol acts primarily on the nerve cells within the brain. Alcohol interferes with communication between nerve cells and all other cells, suppressing the activities of excitatory nerve pathways and increasing the activities of inhibitory nerve pathways.
Speaking of shadowy boundaries... Looking around Digital Militia HQ, I can only assume I received a bad copy of the employment agreement as mine seems to say "No Drinking in the Production Center".
