I used to aspen for my snakes. But it was just easier to use newspaper now. Plus I got bundles of it for free.
Snake aspen is the same as rodent aspen. It may be a little less dustier and a different shape, but its the same stuff.
When I used aspen for snakes, I used Native Earth Shredded Aspen. Their sanichips are good to use too.
I fed live on the aspen. A little ingested substrate isn't going to harm your snake.
