You might also have a bad heater core that needs to be replaced. You can either attempt to flush it out or just have it replaced. Heater cores are not extremely expensive, but I would recommend changing the thermostat at same time. Thermostats are normally $10 to $20 where a heater core can be anywhere past $50.

Why would a car leak antifreeze only when the heat is on inside the car but doesn't leak when the heat isn't on?

The heater in a car is a little radiator under the dashboard. It's called the heater core. There's a valve in the water system that sends hot coolant into the heater core when you turn on the heat, and keeps the coolant in the engine when you don't want heat. If the car is leaking antifreeze when the heat is on but not when it's off, something in the heater system has a hole in it. Because there's always coolant in the heater core and the hoses that feed it, my first thought is the valve itself is bad.

What can cause white smoke coming out of vents?

That is probably antifreeze steam. Your heater core is a small radiator used to heat your car. The engine heats the antifreeze and circulates it through the heater core. Your blower blows heat through the core (radiator) into the car, and warms you. If the core gets a small leak, it will put out steam.
