More Awesome Than You!

First I have a legitimate reason for asking for this.

I am fiddling with a Dune like neighborhood. I need something that if not taken everyday will kill sims. I suppose I could do this with food, but there are folk I do not want to have access to it. I have tried various potions and so on. I remember a "simdrug" that existed as a first hacked object in the original sims. (some college class that created it) It was rather amusing to watch, I put it on a community lot. When that lot loaded the whole game went to this object first before doing anything else. I would not want the attractiveness of the drug to be so much that it is the "only" fun object. I suspect it might need to be anti fun, thus only those that "have" to have it would use it. Shoot I don't know if this has even been done (been searching content lists). I figure if not used in three sim days death occurs?

If anyone else has a good idea for a substitute for melange , by all means direct me there.
