Catnip is actually not a drug. The active ingredient is nepetalactone. It
simulates a cat pheromone. It has no effect on cats if given systemically,
either by mouth or IV (unless the dose is high enough to activate
olfactory receptors from the bloodstream. It only causes the behavioral
effects by olfactory stimulation. Unfortunately, I do not know what is the
role of the pheromone that it mimics.
