Whenever I start the car it smokes than after
The key is how much smoke? Does the smoke have a smell to it. Are you consuming any fluids, like coolant, or oil?
Tons White smoke that is sweet smelling is usually coolant getting into the combustion chamber.
Less white smoke, especially if other cars are doing it, is normal. For every gallon of gas that you burn, you generate a gallon (GALLON) of water. so this water usually evaporates, but sometimes not. It has little or no smell.
If the smoke is bluish white, that is oil, but usually your converter would fill with oil, and cause error codes, or loss of power. This smell is distinct, but not necessarily sweet.... After the converter heats up, it may be able to burn off the oil and the smoke stops.
What are you consuming, fluid wise, will direct where you go next.
