Hey, KanMan, thanks for the link.
We have seen the mouse party a lot here, and if it's OK, I'm going to slide this thread into our Medical area, where I think it belongs best. The whole U of Utah addiction site and not just the mouse party are very well done and important for people to read and understand, I think. The background and the information about neurological pathways is particularly helpful to understanding what they're really describing in the descriptions of the effects of each major substance on our brains in the mouse party.
