I should also point out that the odor of pine is caused by molecules of the volatile oils in the wood. If the oils were gone, it would no longer have that fresh, piney smell. So there's no such thing as pine that has an odor but no volatile oils in it.
Newspaper is cheaper, safer, and a lot less messy. I gave up on using particulate substrates when I realized how much snakes pee (spot-cleaning=icky), and how much more expensive they were. Newspaper poses no hazard of ingestion, can be gotten for free if you talk to some delivery people, and lets you keep the bins odor-free.
