Question

How do musicians that actively talk about their illegal drug consumption not immediately get arrested, if their music acts as a confession?

In:

Answer 1

Simple: Their music doesn’t act as a confession. Music is a performance, you wouldn’t arrest an actor for being a murderer just because they play one in a movie would you? Similarly you wouldn’t arrest Eric Clapton for admitting he shot the sheriff, and you can’t arrest a rapper for saying they are “ridin’ dirty”.

All they would need to do is claim their statements were a performance (which they really shouldn’t need to do) and no judge would accept their performances as probable cause for a search.
