All the drug traffikers can setup shop in blue states and distribute to the rest of the nation.
My favorite argument with immigration has to be drugs. Assuming this would even have an impact on the current drug trade, you don’t think the cartel can push drugs through US citizens or that US citizens wouldn’t just take over the abandoned territory if they were all deported? People don’t do drugs because they were duped by undocumented immigrants. They do them because drugs.
