I read the other day that even humans can be effected (or is affected?) by catnip. Apparently the ancient Egyptians used to make catnip tea to get high.
This brings me to the issue of the nipothal vehicle. If we are putting out the sweet fumes of catnip when we drive, are humans also going to get high? Will it be a problem while they are driving?
Or will it just make them nicer to each other and issue in an era of world peace?
