Nicotine is interesting because it’s a stimulant, it may increase intelligence (I believe Daniel Kahneman said he was smarter back when he used to smoke)
I find it unlikely that there a strong case for it increasing intellgience and the tabacco companies not having run the studies to prove the effect.
