Abstract
BACKGROUND: The cannabis industry has an interest in creating a regulatory environment which maximizes profits at the cost of public health, similar to the tobacco, alcohol, and food industries. This study sought to describe the cannabis industry's lobbying activities in the Colorado State Legislature over time. METHODS: This retrospective observational study analyzed publicly available lobbying expenditures data from fiscal years (FY) 2010-2021. Measures included inflation-adjusted monthly lobbying expenditures by funder and lobbyist, origin of funding, and lobbyist descriptions of cannabis industry clients. This dataset was supplemented with business license documentation, legislative histories, and public testimony. RESULTS: The cannabis industry spent over $7 million (inflation adjusted) from FY 2010-2021 to lobby the Colorado legislature on 367 bills. Over $800,000 (11% of total cannabis spending) was from out-of-state clients. In 48% of lobbyist reports lobbyists did not disclose their funder's cannabis affiliation, and cannabis organizations used strategies that may have obscured the true amount and source of funding. Lobbyists and agencies concurrently represented the alcohol, tobacco, and cannabis industries, possibly facilitating inter-industry alliances when interests align. CONCLUSION: The cannabis industry dedicated significant resources towards lobbying the Colorado State Legislature on behalf of policies intended to increase cannabis use. Creating transparency about the relationships between the cannabis industry, related industries, and policymakers is essential to ensure appropriate regulation of cannabis products.
