More on the GOP invasion of Mexico

I have heard of that one but have not read it. A required text for me in back human psych 101 was called simply, "Intoxication." Do not recall the author, but it demonstrated that not only is the drive to get high a natural and normal human condition--sometimes overriding sex and even food--but is also pretty widespread throughout the animal kingdom. From birds to snails, almost everybody seems to need to enjoy an altered state of consciousness. I recall a study of a particular species of snail; it would make a long journey--for a snail--of sometimes up to an hour or more, bypassing much good food along the way just to get to a particular plant where it would crawl all the way to the top to eat the new intoxicating leaves until it lost its grip and fell to the ground. Then it would wake up and do it again.
