Opium

Opium is a narcotic drug made from poppies which can be ingested, smoked or taken intraveinously, although the latter method is probably not known in Rokugan. Opium is very illegal, with the narrow exception of certain medicinal uses. Opium is offered in special opium houses that operate out of the shadier sake houses and geisha houses. Despite the drug's illegal status it is not rare for a samurai to secretly indulge in this vice. The Tortoise Clan is allowed to conduct opium trade and run opium houses.
