Nicotine’s stimulant properties rapidly fade after prolonged use. About increased intelligence, the effects seem minor and only exist for low doses and disappear with prolonged use: http://www.ncbi.nlm.nih.gov/pubmed/20414766
It seems that nicotine produces a combination of stimulant and sedative effects, the latter which may be more pronounced sometimes and can be unpredictable. This is consistent with my own experience. I experimented with occasional smoking of normal cigarettes (I never got addicted to them, however).

I think that’s only with frequent and repeated use. The optimal use might be to create a stack and rotate with other nootropics.
