Use this set of 100 Mini-Lung™ Refill Sheets for tobacco education demonstrations with our Hand-Held Mechanical Smoker (item #79202). Each sheet shows an image of an actual lung X-ray that becomes covered in tobacco tar and nicotine when the Hand-Held Mechanical Smoker is used to “smoke” a cigarette, as shown in the second image here. It also explains how every cigarette smoked equals time of life lost to smoking.
