I have enough proof for me

Enough proof for you doesn't equate to scientific proof or enough proof for several million others.
I don't deny that nicotine CAN be an addictive substance. Some are able to resist addiction better than others. (scientific fact)
So, what's addictive for one person may not be for another. To lump all smokers into the lump of "addicted" is not at all correct and condensending as all get out.
And like another poster said, until the surgeon general changed the term "addictive/addicted/addict" ANY smoker was not considered "addicted". Since that time, chocolate is also an "addictive" substance.

"Some are able to resist addiction better than others. (scientific fact)"

Well, now we're getting somewhere, you now admit that smoking is addictive to at least some people. I don't have to have a government agency to prove to me that the planet Pluto exists although I haven't seen it. The evidence is unquestionable. The evidence is even more clear to me that smoking makes you sick and shortens the life of most people.
