A blown headgasket. The anti freeze gets into the exhaust, gets heated up by the catalytic converter and blows smoke out of the exhaust pipe. The reason that you don't have heat is because the antifreeze/water is leaking into the combustion chamber.
Another thought...If the 'smoke' is actually vapors coming through the heating/cooling ducts, that could be a leaking heater core.See "Related Questions" below for more
