Past or possible reason to be in Coma
Most probably thing is that her/his hooligan attitude, and his/her excesses only bring her/him a bad health, or had an accident for mixing wrong substances, but that's not really possible since the author or the game itself didn’t specified if he/she uses other kind of drugs than tobacco and alcohol.
