The toxic gift: reciprocity and social capital in cigarette exchange in China.

The widespread exchange of tobacco cigarettes as a gift in some societies normalises the symbolic desirability of tobacco products and promotes smoking. Little is known about how and why people exchange toxic substances as gifts. This study argues two key factors involved in social exchange processes - reciprocity and social capital - can explain gift cigarette circulation. We conducted a multistage survey among household heads from China and measured the quantity and monetary values of outgoing and incoming gift cigarettes circulated by each household and measured social capital in three dimensions: collective participation, social ties, and trust. Ordinary Least Square regressions showed that reciprocity is strongly and significantly associated with both the value and quantity of gift cigarettes. All three dimensions of social capital are varyingly associated with gifting cigarettes. Income and higher classes are also associated with greater quantity and value of received cigarettes. This study broadens the phenomenon of gifting cigarettes to the more universal patterns of reciprocity and social capital, wherein better social capital and socioeconomic position ironically lead to a higher risk of tobacco use and endanger health. We suggest policymakers target the endemic social need for gift exchange in China's informal economy.
