Question: how long will it take to smoke a 3 pound brisket?
Answer: The guidelines start to break down when you are smoking smaller pieces like a 3.5 pound section of brisket flat. A small section of brisket, say 3-4 pounds, will still take at least 5 hours to cook and that is if you are wrapping in foil after it has smoked for at least 2 hours.
