Does nicotine have the same effect? (Score 1)

Would nicotine produce the same results, sure its bad for your lungs, and your lip, but I imagine it has some rather odd effects on your brain. Any 'chemical' or 'drug'(mind you) alters the way your mind operates, and the way your mind produces, and utilizes chemicals. I also wonder, if you have a lack of sleep, does caffeine stimulate these cells a lot more? =) --Brian
