<p>High-purity nicotine is produced through purification from ingredients removed during the production of low-nicotine low-tar tobacco leaves. The high-purity nicotine is adhered and/or adsorbed onto ordinary tobacco leaves to give a high-nicotine tobacco. This tobacco, having a high nicotine content, is intended to be smoked in a small amount and thereby eliminate stress and nicotine toxicosis. Thus, the amount of smoking can be reduced.</p> |
