Do broadcast standards and practices for TV networks in the USA not extend to advertising?

It would be very strange for them to e.g censor certain kinds of drug references in the programmes they produce and air, but then permit them in adverts, no?

There are rules. Networks have entire departments called Standards and Practices. But only because broadcasters don't pay for spectrum. Cable has laxer rules and almost none on anything streaming.

Across all of these, if any government or pseudo government body attempts to restrict advertising because of the content, they will get sued. Any advertiser making materially false claims will likewise also get sued.
