\nOne more interesting article about addiction and self-control and then I’ll let you be to all your vices (as long as you don’t bug me about mine).
\nA recent New York Times\/AP story (that you can get to by clicking here)<\/a> reported that scientists have pinpointed a susceptibility genetic link that causes people to be more likely to become addicted to tobacco and nicotine. According to the article:<\/p>\n

The discovery by three separate teams of scientists makes the strongest case so far for the biological underpinnings of the addiction of smoking and sheds light on how genetics and cigarettes join forces to cause cancer, experts said. The findings also lay the groundwork for more tailored treatments to quit smoking.
\n\u201cThis is kind of a double-whammy gene,\u201d said Christopher Amos, a professor of epidemiology at the M. D. Anderson Cancer Center in Houston and author of one of the studies. \u201cIt also makes you more likely to be dependent on smoking and less likely to quit smoking.\u201d
\nA smoker who inherits this genetic variation from both parents has an 80 percent greater chance of lung cancer than a smoker without the variants, the researchers reported. And that same smoker on average lights up two extra cigarettes a day and has a much harder time quitting.\n<\/p><\/blockquote>\n

<\/p>\n

The three studies, financed by governments in the United States and Europe, are being published Thursday in the journals Nature and Nature Genetics.
\nThe scientists surveyed genetic markers in more than 35,000 people in Europe, Canada and the United States, zeroing in on the same set of genetic differences. They are not quite sure if what they found is a set of variations in one gene or in three closely connected genes. But they said the result was the same: These genetic quirks increase the risk of addiction and lung cancer.
\nThe studies\u2019 authors disagreed on whether the set of variants directly increased the risk of lung cancer or did so indirectly by causing more smoking.
\nThe genetic variations, which encode nicotine receptors on cells, could eventually help explain some of the mysteries of chain smoking, nicotine addiction and lung cancer that cannot be chalked up to environmental factors, brain biology and statistics, experts said.<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"
