It's actually probably a lot more than CYA insofar as civil liability is concerned. IIRC Meth in particular is a drug in a class all by itself with respect to the first amendment. The Methamphetamine Anti-Proliferation Act of 1999 contained language sufficiently broad enough that merely hyperlinking to instructional content on the Internet would have been considered a federal crime because doing so would constitute knowingly providing information that would aid in the production of a controlled substance. I don't recall if the language that would have had first amendment implications made it into the final bill or not. Even now the USG is trying to stifle free speech by going after people teaching techniques on how to beat polygraph tests.
