Influences on cannabis policy design and adaptation in the American states
研究美国各州医用和娱乐大麻政策的设计与演变，发现政策设计受邻州及意识形态相似州的影响，同时内部因素如政党构成、公民意识形态和残疾福利人口比例也起作用。
Abstract Despite federal prohibitions, three‐quarters of states had implemented medical marijuana laws (MML) and one‐third had implemented recreational cannabis laws (RCL) by 2020. State policy designs varied considerably, and we focus on policy development and maturation in policy implementation, examining factors influencing design features of policy bundles for MML and RCL policies. Using data for 50 states from 1994 to 2020, we categorized 36 policies into three distinctive policy bundles. The pharmaceutical bundle regulates cannabis like other medicinal drugs. The permissive bundle gives individuals discretion to use cannabis with minimal state regulation. The fiscal bundle treats cannabis as a state revenue source. Most importantly, policy design choices continue beyond adoption into implementation, and each bundle score can change over time and by state. Using panel regression with state and year fixed effects, we test five influence pathways for the policy design of cannabis policy bundles: (a) the average bundle score of neighboring states, (b) the partisan‐weighted neighbor average, (c) the neighbor average weighted by citizen ideology, (d) the average of all states with similar unified party control, and (e) the policy leader bundle score weighted by ideological similarity. Models also include partisanship, economics, public finance, citizen ideology, demographics, and policy‐specific variables. Besides internal factors of Democratic legislative composition, state citizen ideology, and the relative percentage of a state's population receiving disability benefits, we find support for external cue‐taking from other states, particularly among those with similar ideological leanings.
