Because Demon bodies naturally use their own stores of energy to heal, any ingested poisons begin to break down immediately, rendering almost all alcohol ineffective. 

The solution to this is to lace the alcoholic brew with MALICIOUS demonic energy, allowing it to actually fight the demon's body as it takes effect.

This creates an incredibly unpleasant flavor and actually causes pain both during ingestion and especially the next day.

In spite of this MANY Demon's find demonic brew to be highly addictive and interventions are OFTEN necessary.

We advise all Demons to ABSTAIN from the consumption of such beverages, as they cost you physically, mentally, and can drain energy reserves!
