A Piper's Tip of the Week: Not allowed to smoke your pipe in the house? Well, here is the solution for you.. a charcoal disc. Simply heat up the disc and sprinkle your favorite blend on it and voila!! When your significant other or roommate returns home and scorns you for smoking your pipe in the house, you inform them that you didn't smoke your pipe in the house. Simply point to the charcoal disc and say it's tobacco incense.
