In countless studies since Eysenck’s groundbreaking work, this picture of the smoking “type” has been filled out. Heavy smokers have been shown to have a much greater sex drive than nonsmokers. They are more sexually precocious; they have a greater “need” for sex, and greater attraction to the opposite sex. At age nineteen, for example, 15 percent of nonsmoking white women attending college have had sex. The same number for white female college students who do smoke is 55 percent.
