This article explores the notion of negative reciprocity. It uses the
experience of drug dealers who sell poor quality heroin to consider th
e problem conceptually. The article examines the disclaimers and accou
nts dealers make while attempting to balance negative reciprocity. Dis
claimers warn customers before the sale that product quality may be su
b-par and that they may wish to pass. Accounts neutralize customer com
plaints after purchase and consumption and centrally involve two types
: appeals to defeasibility and counter denunciations. Conditions under
which dealers use either disclaimers or accounts-and sub-types within
these axial categories-are specified, The discussion uses dealers' ex
perience to expand and modify existing conceptualization on the norm o
f reciprocity. Data were drawn from interviews with 32 semi-institutio
nalized heroin user-dealers located in a large western city.
