1) Tobacco use has not dropped 50% since 1990. In 1990, the rate was about 25% of the US pop. In 2006, the rate is about 21%, according to the CDC. Not quite your 50% drop. Additionally, that drop can be largely attributed, not to your precious education, but to laws passed outlawing smoking in public places. California, for instance, had a much larger drop in smoking rates than the nation. Almost certainly the aggressive anti-smoking legislation passed there has had a large effect on the smoking rates. Care to make a correlation with drugs?
2) To compare nicotine to scheduled narcotics in addiction potential is somewhat laughable. (Cue laugh track)
Very true.

Nicotine is more addictive than many of those. It's also at least as harmful than the most common drug of abuse, that is marijuana, and much more addictive.
