Among California young adults, more dispensaries near their home was linked to higher levels of cannabis use, though this differed for different ingestion methods

Abstract Background and aims: The impact of exposure to cannabis dispensaries on young adult cannabis use may depend on how exposures and outcomes are defined. We estimated associations of dispensary exposure with young adult cannabis use across: (a) a government-maintained licensed dispensaries registry versus a web-scraped list of licensed and unlicensed dispensaries; and (b) varying modes of cannabis modes (i. e. smoked, edible, vaped).
