It is vitally important that you never saw or sand such treated woods casually. I wouldn't, for example, age my moonshine whiskey in casks made of such wood either. (Note to self: get new whiskey casks...) But casual exposure to such woods in-tact is safe.
By the way, the bigger risk is from some exotic hardwoods which actually contain natural oils that are poisonous. Tulip wood (which, like rose wood, has no relation to the flower that it shares its name with) is a good example of this. Artists who work tulip wood need to be very careful about exposure to the dust and fumes.
Mother of Pearl is widely reputed to be poisonous. It is not. But, the dust is very irritating and some people are highly allergic to it.
By the way, you'd better call the poison center because I just ate some cyanide. No, I'm not committing suicide. I just happen to like these almond cookies. Yes, almonds contain a small amount of deadly cyanide (apple seeds do too). My point is that exposure to a tiny amount of a deadly poison is not necessarily a terrible thing. But, the media likes to grab ahold of certain emotional words such as Arsenic and Poison and blow it all out of proportion.
So, while you're reading all the goings on about arsenic in drinking water, you'd better not be eating any almond cookies.
