First, you can't become a "DEA" - DEA stands for Drug Enforcement Agency, an Agency within the Federal government of the United States. The DEA has people with a wide educational background, ranging from those with a high school diploma only (typically working in administrative support) to those with multiple graduate degrees (typically those in policy making and other scientific positions).
However, if you want to work as a DEA agent, working in the field tracking drug shipments and working to stem the flow of illegal drugs, you probably need to complete at least four years of college and earn a bachelor's degree in corrections, forensics, criminal science or another related field.
You do not have to go to college.
