Yahoo! News - Hostile People May Be 'Born to Smoke', Study Finds
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.

HEY! Fuck you, man! Who you callin' hostile? Well, no shit, when you raise the goddamn taxes so high on our drug of choice, hell yeah, we are hostile!
