If you're looking for a smokeless, tobacco leaf alternative to traditional cigarettes, you may want to try a heat-not-burn device. These devices heat tobacco leaves to release a nicotine-containing vapor, which is then inhaled. Heat-not-burn devices are a relatively new product on the market, so there's not a lot of long-term data on their safety. However, initial studies suggest that they may be less harmful than traditional cigarettes, since they don't involve combustion (burning) of the tobacco leaves. If you're interested in trying a heat-not-burn device, be sure to do your research and purchase one from a reputable manufacturer.
