Cast Inflict Addiction on any npc to make them into a real skooma addict. They will drink the first potion in their inventory and will search high and low for more skooma. When they find more they will drink it and then continue looking for more skooma to drink. Never wears off. The npc will also receive Diary of a Skooma-Eater book into their inventory.
The other spell "The Pusher" adds a few skooma into target(inventory or container)which is fun if you want addicts to run around pickpocketing or even killing other npcs to get their fix. Npc addicts with low or no responsibility will most likely kill for it.
Also adds skooma to some leveled lists so there will be more around in sacks and containers for the addicts.
