A device for filtering second-hand smoke from a burning tobacco product includes a first chamber for receiving the lit end of the tobacco product. Users of the device can inhale smoke from the tobacco product through a first aperture in the first chamber, while a filter communicating with the first chamber filters smoke from the burning end of the tobacco product. A second chamber is configured to receive smoke and air exhaled by the user. The smoke is filtered by the second filter and the filtered air is passed through to the surrounding environment.
