Where did the name Nicotine come from?

I was in a geeky mood and was browsing’s QDB.
I stumbled across this quote:

<etc> so tempting to release a product called ‘nicotine’ and wait for the patches.
<etc> then i would have a reason to only apply one patch a day. otherwise, i’m going against medical advise.

So I thought what the hell and bluntly stole etc’s idea.
