[AJO]

Får man lägre iq av nikotin. Finns det överhuvudtaget något samband mellan Iq och nikotin?

[King Grub]

Minnesfunktionerna försämras i alla fall av kronisk rökning.

A significant age and smoking status interaction was identified with older smokers performing more poorly than older nonsmokers and younger smokers on a measure of long-delayed recall of new information. Cigarette smoking is associated with isolated and subtle cognitive difficulties among very healthy individuals.

Akut nikotinpåverkan verkar dock ha motsatt effekt:

We therefore hypothesised that nicotine is acting to improve intellectual performance on the elementary information processing correlates of IQ. In the current experiment we tested this hypothesis using the Raven Advanced Progressive Matrices (APM) test. APM scores were significantly higher in the smoking session compared to the non-smoking session, suggesting that nicotine acts to enhance physiological processes underlying performance on intellectual tasks.
