Generally speaking, is it a good idea to fish low voltage cables through a plumbing chase?

I want to specify that I was wondering about using the same cavity (A plumbing chase), not using the actual plumbing vent (DVW Pipe) itself.

    I think the answers need a clarification; do mean inside the pipe itself, or just in the wall cavity next to the pipe?

    @ThreePhaseEel - an addendum would've been better than deleting or editing outright your answer. It's N/A, but "IPC 901.4 (aka IRC P3101.3)" is what to look for.

Yes you can run low voltage and even mains voltage in the same cavity your plumbing is using.

I say this with the understanding that the cable is rated for the chase construction (some made out of brick / concrete the cable would have to be listed for use enclosed in brick or concrete).
