That depends on where the pallets are coming from - not all pallets use treated wood. When I was in FL I had a bunch by CVS(they throw em away) and I took em home and built me a shed out of em. Most economical thing I've ever done. I've also used em in the wood stove with good success and no fumes/toxicity.

Just my 2 cents,
