"The bottom line for smokers is to be aware that just because they smoke 12 cigarettes a day instead of 20 doesn't mean that they are less dependent on tobacco," says Ahijevych. "As clinicians, we need to understand that a person who smokes half a pack a day may...Super-effective 'jumping gene' created
