Neutral Wire for Smart Switch

Howdy,


I'm looking at putting in a couple of smart switches, and remembered after I got them that I had wired my old switches at the end of the circuit so I don't have the neutral wire extending to the switch box. I do have an outlet a few feet below the switches that is on the SAME circuit as the lights, however, so I was thinking about running a short length of Romex up to the switch box to borrow a neutral from there. Given that these are on the same circuit, is there a safety concern with doing this? I've seen conflicting information on message boards for smart switch manufacturers, and I don't necessarily trust anything I read there, so I thought I'd look for some more knowledgeable advice here.


Thanks in advance. I know that ideally I would just run some 14/4 Romex from the lights, but at this point that would require tearing up a lot of drywall, so if I can't tie into the neutral nearby, I'll just have to try to return these switches and get some that don't require the neutral.
