That nicotine is placed so high is kind of suspect. Missing some factual accuracy here, given that it's tobacco/smoking which is addictive due to additional chemical compounds. Otherwise nicotine should be next to or below caffeine. 122.106.154.228 (talk) 07:03, 28 November 2012 (UTC)
I agree with the comment that nicotine should not be placed highly — Preceding unsigned comment added by 216.162.151.148 (talk) 07:33, 28 November 2012 (UTC)
