Where should an extension tube go with an EF lens, EF-EOS M adapter, and EOS M camera?

I’m using an EF lens on a Canon EOS M camera with an EF-to-EOS M mount adapter, and I want to add an extension tube for closer focusing. Does it matter whether the extension tube goes between the EF lens and the adapter, or between the adapter and the camera body? Are there any practical issues to watch for?

You don't really say, but it seems you have an EF lens and an EOS M camera?
They have different diameters, so does it make any difference if I put it between lens and adapter or between adapter and camera?
You can do either.
You can use EF-M extension tubes with the smaller diameter mount between the camera and the adapter.
You can use EF extension tubes with the larger diameter mount between the adapter and the EF lens.
Which you decide on probably will not make much of a difference.
What will make a difference is whether the tubes have the proper electrical connections to allow the cameras and lens to communicate. You probably want to be sure and get extension tubes with the proper camera to lens connections. Third party makers often call such extension tubes "Automatic" ones.

Either position can work.
- Put an EF extension tube between the EF lens and the EF-EOS M adapter, or
- Put an EF-M extension tube between the EOS M body and the adapter.
In normal use, there usually isn’t a major optical difference between the two placements. The bigger practical concern is compatibility: use tubes with the correct mount for the side where they’re installed, and preferably ones with electrical pass-through contacts so the camera and lens can still communicate for aperture control and other functions.
Possible minor differences:
- Internal reflections/glare may vary depending on which part is closer to the sensor.
- Handling and balance may feel different depending on whether the smaller or larger tube is near the camera.
- Adding more connections can introduce a little mechanical play, though this is often minor.
So the short answer is: either side is fine, as long as the tube matches that mount and ideally maintains electronic connections.
