A good way to look for statistics and facts that are easy to find is to search on Google Scholar, or to use a regular Google search but put "government" into your search. Make sure you look up a government website, which will provide authoritative sources. I searched "government alcohol facts," and came up with both a Centers of Disease Control Fact Sheet and also a National Institute of Health Alcohol Facts and Statistics website. What is great about these websites is that if you look at the bottom of the article, they usually have links to the original papers. Those papers are excellent sources for your research, and can often give you plenty of information for your paper. Ask your instructor to see if they will also accept the government websites as research sources. A final way to get sources is to look for a medical or non-profit organization that researches that topic.
