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.
If you'll be smoking your pork shoulder at 200Â°F, it could take an awful long time to smoke, maybe 2 or more hours per pound. If at all possible, smoke your shoulder at a higher temperature, around 220 degrees. 10-12LB pork shoulder cooked at 225 for about 14 hours is done. You'll use probably 25LBs of charcoal to achieve this, and your hair will smell like smoke for 2-3 days even after washing.
