Can we outlaw genes instead?

While we’re talking about smoking, this study points out something that, intuitively, I’ve long considered obvious:

Heart attacks among cigarette smokers may have less to do with tobacco than genetics. A common defect in a gene controlling cholesterol metabolism boosts smokers’ risk of an early heart attack, according to a new study. The findings also show that smokers without the defect normally have heart attacks no sooner than their non-smoking peers.
