that'd be my concern. but, if they're untreated, go for it.
that being said, theres companies out there that sell untreated white oak that you can cut into sticks just as easy, and soak in bourbon or port wine all you want to accomplish essentially the same thing - with less random chemicals.
you could even bulk age a homemade port wine on the oak for a year to suck out most of the tannins, and then use the sticks for homebrew... and it gives you a bunch of port wine to boot.
