Just one question about your little comment: How does smoking cigarettes make someone a drug addict?
I completely understand your thoughts on everything else, but that one statement made me laugh... a little. 
I am actually trying to quit. I've cut back a lot, so, so far, so good.
Sorry for my ranting on this post, it was in regards to someone elses goofy post.. I just had to let it out.
I titled it the way I did because I found it humorous

3: something and often an illegal substance that causes addiction, habituation, or a marked change in consciousness From wikipedia on nicotine: According to the American Heart Association, nicotine addiction has historically been one of the hardest addictions to break, while the pharmacological and behavioral characteristics that determine tobacco addiction are similar to those that determine addiction to drugs such as heroin and cocaine.
Also from wikipedia: Modern research shows that nicotine acts on the brain to produce a number of effects. Specifically, its addictive nature has been found to show that nicotine activates reward pathways—the circuitry within the brain that regulates feelings of pleasure and euphoria.
That is why it was called a drug, because it is one.
