The Journey of a Kidney Stone. To really understand how long it takes a kidney stone to pass, you should understand exactly where it goes throughout the body. Kidney stones start in the â you guessed it â kidneys. They have to pass through the long ureter tubes and eventually make their way into the bladder.
Pork shoulder cook time can be figured at approximately 1.5 hours per pound so a 8 pound shoulder will require about 12 hours in the smoker.
About 1 hour to 1.5 hours per pound. I personally go with the 1.5 per hour you cant ruin a pork shoulder and the smoke is only good for the for 1 hour to 2 hours. Cook at 225 degree 4.5 to 5hours.
