Awhile ago I saw a post about somebody asking if they were a "tobacco user" because of the nicotine in eliquids. It is refined from tobacco so I guess indirectly we would be but here's the question I have. Couldn't the nicotine technically have been refined from one of the other plants in the family of tobacco? If the nicotine was refined to the point were it was as pure as possible, what would be the difference? Obviously there's a reason or we'd be getting nicotine from something else. Is it cost, complexity? Do the other plants that contain nicotine have some other chemical that's hazardous?
