It's fine as a dry substrate. I don't have any problems with it under normal everyday use as long as it doesn't stay wet for days. In the normal housing enclosures with a basking lamp I get it wet sometimes to increase humidity or the snakes will occasionally get it wet but as long as it dries out in a timely manner (and it does in their regular housing w/heating) it doesn't mold. If you're wanting a wet area or wet brumation substrate then yes obviously there's better choices.
