Does nicotine help brain function?
Preclinical models and human studies have demonstrated that nicotine has cognitive-enhancing effects, including improvement of fine motor functions, attention, working memory, and episodic memory.
Does nicotine kill brain cells?
Nicotine can kill brain cells and stop new ones forming in the hippocampus, a brain region involved in memory, says a French team. The finding might explain the cognitive problems experienced by many heavy smokers during withdrawal, they say.

Nicotine acts as both a stimulant and a depressant to the central nervous system. Nicotine first causes a release of the hormone epinephrine, which further stimulates the nervous system and is responsible for part of the “kick” from nicotine-the drug-induced feelings of pleasure and, over time, addiction.

How does nicotine kill brain cells?
The mitochondria then swell, changing their morphology and function. They can even rupture and leak molecules that lead to cell death. “If the nicotine stress persists, SIMH collapses, the neural stem cells get damaged and could eventually die,” Zahedi said.
Are smokers smarter?
NEW YORK (Reuters Health) – Cigarette smokers have lower IQs than non-smokers, and the more a person smokes, the lower their IQ, a study in over 20,000 Israeli military recruits suggests. Young men who smoked a pack of cigarettes a day or more had IQ scores 7.5 points lower than non-smokers, Dr.
