Smoking fetishism (also known as capnolagnia) is a sexual fetish based on the sight or image of a person smoking. For many the fetish appears to have had its roots in early childhood for man. The fetish is a classically conditioned behavior. The root for this behavior is often shaped by many variables. This could include seeing the smoker as a stereotypically sweet, innocent individual behaving in ways that are considered taboo. For others it stems from an attraction to more worldly person, whose smoking epitomized their strength and self-confidence. Within gay culture, this fetish often stems from the image of masculinity.
