I have a 97 Buick Regal LS 3800 series engine v6...a couple days ago I noticed after I start my car up and accelerate then put it back in park a little amount of smoke comes from the exhaust pipe, but goes away completely after I start driving for a few minutes....even on real warm days tho, theres no smoke when I start it up just after i accelerate a bit then put it back in park and go around to my exhaust pipe i can see little smoke comin out what may be causing this should i worry?????

If engine running OK and not loosing any coolant, not a problem usually condensation in exhaust system normal. If grayish color oil if black fuel if white smoke and smells sweet coolant if like wisps of vapor Ok.

It could be probably what was answered above or maybe a rich burn relating to other causes.
You have a 97. How many miles are on the engine?
Check the oil often, maybe you might have a valve stem seal problem but the color would be blue
I'm not saying that's what it is but check that.
