Intoxication is a tier 5 symptom exclusive to the Christmas-themed Santa's Little Helper scenario. It makes hosts overindulge and say silly things, which increases infectivity but decreases happiness because of a hangover. Evolving this alongside the symptoms Gluttony and Sloth unlocks the On The Naughty List achievement. This works well if you do not want to be spotted but still want to infect others.
