The question.. do one time use of cardamine causes insta addiction?
Now blood is something which is in time replaced by new blood cells and blood plasma. (cycle is around a month, medics might be more correct)
You do not need constant cardamine supply to make blood functional, and in time all that blood will be replaced. So I can assume is more like one time use of the drug of the persons blood you got into your veis was intoxicated.
Other story with transplanted organs from cardi addicted person. You need cardamine to keep the functional. well that's how my corsair got addicted to it.
