Drug effects are in the Basic Rules of Doxy as they are very in theme at this class.
A character with the right provisions (i.e the right drug) can take a Dose at the start of a night to gain a sepcial bonus in exchange for a penalty.
Getting Pissed: Getting Pissed makes you a lot more energetic and friendly but dangerously lowers your inhibitions.
Taking a Drag: Taking a Drag calms and focuses you though it may harm your appeal stinking like a chimney.
Getting Stonned: Opium is one Hell of a drug! The bonuses are quite astounding but the penalties delibitating to say the least as your stonned Doxy wanders around in a haze.
