Ball Pythons don't live on sand in the wild.. for some snakes it's good, for example some rattlers and some Bitis and Echis.

I believe it can also cause impaction. It doesn't hold water well at all, it goes straight to the bottom of the enclosure. Humidity levels must be extremely difficult to achieve.
