Got a bunch of PT fence posts, looking for build ideas...

I am on a tight budget and have to scrape up whatever lumber i can when I find it. Today I found 30 randomly sized pressure treated posts, 4x4. I was thinking I could make a decent outdoor table, but is it worth the effort? Most posts or articles I see about PT treat it like a loaded gun. Can I safely cut this up and build stuff with it or should I toss it back in the dumpster from whence it came?
