1995 Honda Civic white smoke problems

I HAVE A 1995 HONDA CIVIC EVERY TIME I START IT UP DURING THE MORNING ALOT OF SMOKE COMES OUT OF THE TAILPIPE, AS IT WARMS UP THE WHITE SMOKE DIES DOWN. TROUGH OUT THE DAY IF IT IS PARKED SAY 5 OR MORE HOURS IT DOES THE SAME THING. THE TEMP. AROUND MY AREA RUNS IN THE HIGH 90'S SO I DONT THINK IT GETS TO COLD TO CREATE NORMAL VAPORIZATION. ANY IDEAS WHAT COULD BE WRONG??
