Too much oil in engine, white smoke?

I excessively overfilled my engine with oil (more than 5 quarts) in my 2001 Honda Civic EX. I drained the excess oil out after the car would not allow me to acclerate. After draining the excess oil and refilling it to its correct levels, smoke keeps coming out from the exhaust when the car is idle and when I drive it around the block for several minutes. The smoke is rather light in color (almost white or light grey). What could possibly be wrong with my car and how should I go about this? Thanks.
