Thick white smoke coming out my mufflerwhat could be causing the problem?

Unless you poured the antifreeze into the oil filler (did you?) you could have a blown head gasket- get a mechanic to do a compression test- unless you made that most horrible mistake of mingling fluids- then just change the oil and filter-

I didn't pour antifreeze into the oil into the oil filter, it has been a while since my last oil change, the smoke doesn't smell sweet like most forums have said about antifreeze mixed in the oil, it smells like burning oil or rubber, i also don't know if this matters but the smoke increases as i throttle, its real thick and leaves a visible trail behind my car when i drove it.

Some more information, the car runs good still and the temperature stayed relatively the same didn't overheat but i had drove it 10 mins before i turned back and parked it.

The smoking engine is not good- I always hope my car will just fix itself- but no, it almost always costs money- like I said, consult a mechanic- who knows? maybe it's no big deal- but if the smoking doesn't go away, my guess is still head gasket-
