Q. Where can I find statistics on the Mexican drug war ?
You may find good information from the U.S. Department of Justice's Drug Enforcement Administration (DEA) on their website: https://www.dea.gov/. The following link is to their 2019 National Drug Threat Assessments report: https://www.dea.gov/sites/default/files/2020-01/2019-NDTA-final-01-14-2020_Low_Web-DIR-007-20_2019.pdf . You will need to browse through the links in these reports to find applicable information.
Also, newspaper articles are often a good source for current statistics. From the library homepage http://www.uhd.edu/library/ click on the dark gray tab for Research Guides>>>Guides by Subject>>>News and Newspapers. You will come to the research guide for newspapers with many links to news databases. Click on the gray tabs along the left hand side to see all of the databases by category. Choose a database (I suggest ProQuest Newspapers or Nexis Uni) and enter in some of the following search terms. I also suggest clicking the checkbox for Full Text articles.
Mexican drug war
Mexican drug cartels
Rival drug cartels
Mexico drug trafficking
