It's long been known that sicklers have a higher resistance to malaria than non-sicklers, it has also been long known that Niprisan/Nicosan alters that coincidental advantage.
I think it is hardly an advantage to hope you live long enough w/o the benefit of Nicosan in the hope you don't contract malaria.
It is a false trade.
