由于过去15年来价格数据的可获得性增加，一些研究对非法药物的需求进行了估计，提供了462个价格弹性估计数。估计几个元回归的结果表明，这些价格弹性估计的影响，一些研究特征。例如，不同药物的价格弹性不同，与可卡因和海洛因相比，大麻的绝对值最小。此外，价格弹性估计是敏感的需求是在短期或长期，数量和价格的措施，是否包括酒精和其他非法药物的需求规格，以及需求的位置建模。然而，其他一些因素，包括需求的函数形式、若干规格问题、用于估计需求的数据类型和方法以及出版物销售渠道的质量，对价格弹性的影响较小。版权所有（c）2013约翰威利父子有限公司
Because of the increased availability of price data over the past 15years, several studies have estimated the demand for illicit drugs, providing 462 estimates of the price elasticity. Results from estimating several meta-regressions reveal that these price elasticity estimates are influenced by a number of study characteristics. For instance, the price elasticity differs across drugs, with its absolute value being smallest for marijuana, compared with cocaine and heroin. Furthermore, price elasticity estimates are sensitive to whether demand is modeled in the short-run or the long-run, measures of quantity and price, whether or not alcohol and other illicit drugs are included in the specification of demand, and the location of demand. However, a number of other factors, including the functional form of demand, several specification issues, the type of data and method used to estimate demand, and the quality of the publication outlet, have less influence on the price elasticity.
