一般而言，对药物使用和需求的了解多于对市场和供应的了解，这在很大程度上是因为有人口调查数据，而没有市场数据。虽然家庭人口在硬性毒品使用者中所占比例相对较小，但在使用大麻和参与大麻市场的人口中所占比例很大。本文提供了一个描述大麻市场和收购模式的参与者在2001年全国家庭药物滥用调查报告。我们发现，大多数受访者在室内（87%），从朋友或亲戚（89%）和免费（58%）获得大麻。大麻零售分销似乎嵌入了社交网络，而不是由“专业”卖家主导。尽管与陈规定型的可卡因和海洛因街头市场有这些对比，但也有相似之处，例如有证据表明数量折扣和少数使用者占购买的大多数。我们估计，美国每年大约有4亿人购买大麻，平均购买量很小，大约是6到7个大麻。
Generally more is known about drug use and demand than about markets and supply, in large part because population survey data are available while market data are not. Although the household population represents a relatively small proportion of users of hard drugs, it represents a large proportion of the population using marijuana and participating in marijuana markets. This paper provides a description of marijuana market and acquisition patterns as reported by participants in the 2001 National Household Survey on Drug Abuse. We find that most respondents obtain marijuana indoors (87%), from a friend or relative (89%), and for free (58%). Retail marijuana distribution appears to be embedded in social networks rather than being dominated by "professional" sellers. Despite these contrasts with stereotypical street markets for cocaine and heroin, there are also similarities, such as evidence of quantity discounts and a minority of users accounting for the majority of purchases. We estimate that there are on the order of 400 million retail marijuana purchases in the U.S. each year and that the average purchase size is small, about six or seven joints.
