The Wiki Man: So it might really be true – nicotine is good for your brain

issue 27 April 2013

It was a few months ago, and I had just arrived in Philadelphia. My friend picked me up at the airport — one of those charming, civilised things people do when they live in a city that’s a sensible size.

As I climbed into the car I furtively pulled an e-cigarette out of my pocket. Furtively, because my friend has never smoked, and is better qualified than most to criticise my nicotine use — what with his having been awarded the highest first in biochemistry in his year at Cambridge and being a professor at the University of Pennsylvania and all. I muttered some apologetic comment: ‘E-cigarettes… nicotine but without the carcinogens or something… about on a par with caffeine… not too bad a drug… .’

‘Are you kidding?’ He replied. ‘It’s better than that. In fact I’m not sure that nicotine shouldn’t be compulsory; it improves cognitive ability, raises IQ, boosts memory function, treats mental illness… rats when given nicotine are much better at navigating mazes… .’
