‘Agressieve mensen zijn geboren rokers’

Mensen die genetisch gezien een agressieve of vijandige instelling hebben zijn geboren rokers. Althans, als je dit onderzoek mag geloven.


Dat de behoefte aan roken genetisch is vastgelegd is het onderwerp van meerdere onderzoeken geweest. Eén onderzoek draait nog steeds aan de Universiteit van Amsterdam. Veel van deze onderzoeken wijzen inderdaad in de richting van een genetische basis. Vandaar dat het voor de een moeilijker is om te stoppen dan voor een ander.


De anti-roken maatregelen van tegenwoordig maken echter geen enkel onderscheid tussen typen rokers. En als je dit onderzoek mag geloven dan kun je sommige mensen ook maar beter laten doorroken…


Hostile People May Be ‘Born to Smoke’, Study Finds


Feb 13, 8:14 am ET


WASHINGTON (Reuters) – People with hostile or aggressive personality traits may have genetic tendencies that make them “born to smoke,” U.S. researchers reported on Thursday.

Brain imaging studies suggest that the same genetic variations that give people hostile personality traits may also make them more likely to become addicted to nicotine, the team at the University of California Irvine reported.

“We call this brain response a ‘born to smoke’ pattern,” Dr. Steven Potkin, a professor of psychiatry and a brain imaging specialist who led the study, said in a statement.

Potkin’s team was following up on evidence suggesting that people with hostile personality traits are more likely to become addicted to cigarettes and have trouble kicking the habit.

Writing in the journal Cognitive Brain Research, Potkin and colleagues said they tested volunteers by giving them standard psychiatric personality exams and separating them into two groups — those with higher tendencies to anger, aggression and anxiety, and those with low-hostility traits.

Both groups included smokers and nonsmokers.

They were given nicotine patches to wear and their brains were imaged using positron emission tomography, or PET scans.

The scans showed no metabolic changes in the brain cells of the low-hostility volunteers but the response of the “hostile” personalities was clear, Potkin said.

And the hostile smokers needed a higher dose of nicotine to get the same response that nonsmokers had to the nicotine patch — suggesting they had become habituated to nicotine.

“Based on these dramatic brain responses to nicotine, if you have hostile, aggressive personality traits, in all likelihood you have a predisposition to cigarette addiction without ever having even touched a cigarette,” Potkin said.

“In turn, this might also help explain why other people have no compelling drive to smoke or can quit smoking with relative ease,” he added.

  • I've alllllllways said that asking smokers "do you want to quit?" and reporting the results of that question, as is, is horribly misleading. It's a TWO part question. After asking if one wants to quit it must be followed up with "Why?" Ask why and the majority of the answers will be "because I'm supposed to" (victims of guilt and propaganda), not "because I want to."
