Hard habit to kick

As the Phactor sits here reading science news and getting bits and pieces together for today's classes, here's a not very surprising scientific finding, nicotine addiction is really old.  For how ever long humans have occupied Mesoamerica, there has been nicotine addiction.  Cultures really know their plant resources, until they become urbanized or even worse sub-urbanized, so almost as soon as people discovered the wonderful kick you got from chewing on the leaves or smoking the tobacco plant, it was an addiction.  How could it be any other way?  So do we expect humans to give up their stimulants any time soon?  Pass the coffee.
