Can you smoke pork on a regular grill?

The main difference between a smoker and a charcoal grill is that a smoker keeps the fire away from the food. A smoker contains the fire and keeps the temperature low enough to cook BBQ at temperatures around 200-250 degrees F. A grill is designed to cook hot and fast, but your average charcoal grill can do both. If you keep the fire small and to one side of the grill you can generate low temperatures that are the secret of real barbecue.
