Heat smoker to 225 degrees F. Add wood chips or pellets according to your smoker directions. While smoker is heating, leave pork chops at room temperature to allow the chill to come off of them.
Rub both sides of the pork chops with the bbq rub. Add to smoker and insert a digital meat thermometer into the thickest part of the pork chop. Cook for 1.5 to 2 hours, until temperature reaches 145 degrees.
