背景：美国的十个州、加拿大和乌拉圭已经通过法律，使非医疗用途的大麻生产和销售合法化。现有的研究记录了迅速下降的价格和不断变化的产品组合，但许多细节还没有得到很好的理解：特别是，不同的大麻食用品和提取物产品的受欢迎程度，价格和产品特性-每种产品都提供不同的消费大麻的方式，对健康的影响尚不清楚。本文分析了华盛顿娱乐大麻市场的数据，该市场从2014年7月至2017年10月记录了超过1.1亿笔零售交易。以前关于价格和产品趋势的研究主要集中在草药大麻上，这种大麻占销售的大多数，但份额在下降。本文采用先进的文本分析方法，提供新的见解，包括（A）估计效力数据的食品和（B）确定提取物亚型。模式和趋势描述，跨产品类型，关于THC和CBD概况和每THC的价格.结果：提取物占28.5%的销售额在2017年10月.在分类为亚型的提取物中，近一半被鉴定为“dabs“，另一半被鉴定为“cartridges“。2017年10月，每10毫克THC的价格在食用品中约为3美元，在提取物盒中约为70美分，在其他花和其他提取物中约为30-40美分;固体浓缩物提供了提取物产品中价格最低的THC。价格继续下跌，但已经放缓。高CBD chemovars正变得越来越普遍，但仍然是几乎不存在的花大麻和罕见的（1%的销售）提取products.Conclusion：作为华盛顿的休闲大麻市场已经发展了三年半，在该市场确定的趋势可能作为一个潜在的问题在其他国家的早期迹象。拥有商业非医用大麻市场的其他司法管辖区的立法者和监管机构可能希望制定政策，以应对产品流行度，价格和效力的这些趋势。
Background: Ten U.S. states, Canada, and Uruguay have passed laws to legalize the production and sale of cannabis for non-medical purposes. Available research has documented rapidly falling prices and changing product mixes, but many details are not well understood: particularly, the popularity, prices, and product characteristics of different cannabis edibles and extract-based products-each offering different ways to consume cannabis, with unclear health consequences.Methods: This paper analyzes data from Washington's recreational cannabis market, which has recorded over 110 million retail item-transactions from July 2014 to October 2017. Previous research on price and product trends has focused mostly on herbal cannabis, which accounts for the majority, but a decreasing share, of sales. This paper applies advanced text-analytic methods to provide new insights, including (A) estimating potency data for edibles and (B) identifying extract sub-types. Patterns and trends are described, across product types, regarding THC and CBD profiles and price per THC.Results: Extracts accounted for 28.5% of sales in October 2017. Of extracts categorized to subtype, nearly half were identified as "dabs ", and another half "cartridges ". In October 2017, price per 10 mg THC was roughly $3 among edibles, 70 cents among extract cartridges, and 30-40 cents for other flower and other extracts; solid concentrates offered the lowest priced THC among extract products. Price declines continue but have slowed. High-CBD chemovars are becoming more common, but still are almost non-existent in flower marijuana and rare (1% of sales) among extract products.Conclusion: As Washington's recreational cannabis market has developed over three and a half years, trends identified in that market may serve as an early indication of potential issues in other states. Legislators and regulators in other jurisdictions with commercial non-medical cannabis markets may wish to establish policies responsive to these trends in product popularity, price, and potency.
