Direct democracy, policy diffusion, and medicalized marijuana.

Virtually all studies of policy diffusion are based on statutory enactments by state legislatures. But a substantial number of medicalized marijuana laws were initiated through citizen initiatives and ratified by referenda (I&R). This case study suggests that the diffusion of laws adopted by I&R requires two modifications to the conventional model of policy diffusion.

Postmaterialism and referenda voting to legalize marijuana.

This analysis of county-level voting on 22 state referenda that sought to legalize marijuana for medical purposes or recreational use is driven by hypotheses from post-materialism theory. Separate regression models for each type of policy largely, though not entirely, support our expectations. Voting to legalize both medical and recreational marijuana was greater in counties with larger college-educated populations, a partisan preference for Democratic presidential candidates, and smaller percentages of Catholic, Protestant, and Evangelical adherents.
