Open Question: tooth extracted 5 days ago? Is this healing right?

I had my furthest back left molar extracted five days ago. I smoke from day one, Its day five and the hole is smaller with like white new gums healing in, but the clot has gotten realy small. I can see in the hole a little bit, there's still a clot in there,it's dark red in color. The hole is like half the size it was five days ago. I was just wondering if this is normal and how long til the gums heal over so I can go back to eating whatever I want again.
