This is a good example of the problem with review articles and it's very well done. Totally straight-faced until the part about children smoking. However, I think the use of nicotine as a performance enhancer (not smoking though) is a pretty interesting subject. I've tried chewing nicotine gum and using a patch just to see if I noticed a difference (just a brief experiment I would never do it chronically). I did. Much better concentration, focus, energy etc. I'm curious to see how the "electric cigarette" phenomenon goes. That would be a way to deliver nicotine without the other risks of smoking. From what I understand nicotine is a carcinogen on its on, but I don't know how strong of one it is. It would also be fun to see if we could synthesize non-carcinogenic molecules based on the nicotine molecule with all the positive performance enhancing effects.
