The Oregon Health Authority (OHA) has been accused of withholding a 2021 study that found that higher taxes have a minimal impact on reducing excessive alcohol consumption. The study, which was not shared with the state legislature or a task force studying the issue, found that while higher taxes could reduce overall alcohol consumption by 5%, it would only reduce excessive drinking by about 2%. However, the tax increase could potentially raise an estimated $239 to $245 million in additional revenue per year. The OHA has since apologized for not releasing the report until after its existence was made public.
