JOINT DEMAND FOR ALCOHOL, TOBACCO, AND MARIJUANA

最近的研究表明，通过限制饮酒来限制饮酒的努力 年轻人获得酒类和/或提高酒价已取得成功 减少饮酒，但可能产生了意想不到的后果 越来越多的大麻使用。这些结果更令人担忧的是 最近的一份政府报告显示，青少年中使用大麻 在1990至1995年间几乎翻了一番。为了更好地理解 在酒精等广泛使用的物质中的药物使用模式， 烟草和大麻应对影响政策的变化 这些物质，我们建议探索一个丰富的药物使用数据库- 全国家庭--药物滥用情况调查(NHSDA)。NHSDA问道 受访者详细询问了他们的饮酒经历， 烟草、大麻和他们获得大麻的途径。我们将合并 关于大麻、酒精和烟草价格的州级数据，以及 影响其在NHSDA中使用的州级法律和政策 探索这些物质的使用如何随价格变化而变化 和政策。为了回答几个研究问题，我们将估计 12至20岁青少年对大麻的需求 大麻、酒精和烟草的价格以及国家政策 控制特定于州的特征。首先，我们将确定 大麻的使用是否对大麻的价格敏感， 酒精和烟草。第二，我们将确定是否 影响一种商品(即酒精)的价格和政策的变化 影响其他物质(如大麻)的使用。结果是 这项研究将有助于指导制定全面的政策， 通过两种方式限制酒精、烟草和大麻的使用：它们将 阐明酒精、烟草和大麻的动态和相互作用 用于回应政府政策；他们将量化 旨在限制每种物质的使用的政策的效果，允许 政策制定者需要评估替代政策选择。

Recent studies have shown that efforts to curb alcohol use by limiting youth's access and/or increasing the price of alcohol have succeeded in decreasing alcohol use, but may have had the unintended consequence of increasing marijuana use. These results are more troubling given a recent government report that shows that marijuana use among teens nearly doubled between 1990 and 1995. To better understand how the patterns of drug use among widely used substances such as alcohol, tobacco, and marijuana respond to changes in the policies that affect these substances, we propose to explore a rich database on drug use-the National Household-Survey on Drug Abuse (NHSDA). The NHSDA asks respondents detailed questions about their experiences with alcohol, tobacco, and marijuana and their access to marijuana. We will merge state-level data on the prices of marijuana, alcohol, and tobacco and state-level laws and policies that affect their use into the NHSDA to explore how the use of these substances changes in response to prices and policies. To answer several research questions, we will estimate the demand for marijuana among youths age 12 to 20 as a function of the price of marijuana, alcohol, and tobacco and state policies while controlling for state-specific characteristics. First, we will determine whether or not marijuana use is sensitive to the price of marijuana, alcohol; and tobacco. Second, we will determine whether or not the changes in the price and policies affecting one good (i.e., alcohol) affect the use of other substances (i.e., marijuana). The results of this study will help guide the creation of comprehensive policies that curb the use of alcohol, tobacco, and marijuana in two ways: they will clarify the dynamics and interactions of alcohol, tobacco, and marijuana use in response to government policies; and they will quantify the effects of policies aimed at curbing the use of each substance, allowing policymakers to evaluate alternative policy options.
