Moldy I think you are mistaken....ceder and pine are both softwoods as is pine and fur....as far as I'm aware all hard wood is safe, beach chips, orchid bark, Aspen (i believe this is also a hard wood???????). The toxic stuff come from the odour that soft woods give off from their sap.

A little rule of thumb I use when choosing substrate, if it has a distinctive smell...Dont use it! being really inexspensive may sound great but its not worth getting your herp sick, or dying and Ive seen it happen.

and Joe, youre right usually only softwoods give off odors from thier sap hardwoods like aspen are safe and dont give offa distinctve smell.
