I don't doubt the cognitive boost or the safety of nicotine outside of cigarette smoking... But I was definitely hoping for a more quantitative analysis of the benefits.

Also a lot of this is anecdotal. I know many people (myself included) who are addicted to nicorette gum. They wean themselves off smoking and onto gum. Nicotine is still addictive.

I'm still looking for the "natural Adderall". Maybe socially accepted is the better term. Amphetamines are hard (read: impossible) to beat... Especially if you spent a long time taking them in high doses daily.

Anyway I really hope we get more research in this space. Coffee only does so much.
