This search returns changes listed under the Alcohol Policy Topics section of the site only, and does not include the Recreational Use of Cannabis or COVID-19 policy topics. The increase in policy changes beginning in 2003 is due to the fact that coverage for 10 of the APIS policy topics begins on January 1, 2003. Policy changes prior to January 1, 1998, are limited to changes involving the Pregnancy and Alcohol and Pregnancy and Drugs topics. The most recent year of coverage includes only changes that took effect on January 1 of that year. Changes to Cannabis policies can be viewed using the Changes Over Time tab for Cannabis volumes 1 and 2, and setting the dates to the most recent year.
