Tobacco is the common name of several plants in the genus Nicotiana of the family Solanaceae, and the general term for any product prepared from the cured leaves of these plants. More than 70 species of tobacco are known, but the chief commercial crop is N. tabacum. The more potent variant N. rustica is also used in some countries. Dried tobacco leaves are mainly used for smoking in cigarettes and cigars, as well as pipes and shishas. They can also be consumed as snuff, chewing tobacco, dipping tobacco, and snus. Tobacco contains the highly addictive stimulant alkaloid nicotine as well as harmala alkaloids. Tobacco use is a cause or risk factor for many deadly diseases, especially those affecting the heart, liver, and lungs, as well as many cancers. In 2008, the World Health Organization named tobacco use as the world's single greatest preventable cause of death Tobacco leaf colors range from green (also known as blonde) all the way to black, and understanding the different flavors associated with the colors can help you better enjoy your cigars. Also known as Double Claro or Clarisimo, wrappers of this type can range from a pale blonde all the way to vibrant green. Growth time Tobacco is harvested 70 to 130 days after transplanting by one of two methods: (1) the entire plant is cut and the stalk split or speared and hung on a tobacco stick or lath, or (2) the leaves are removed at intervals as they mature. Flavors Tobacco products like cigarettes, hookah, chewing tobacco, cigarillos, cigars, dry snuff, dip, and nicotine dissolvables have flavorings added to increase their appeal and palatability. Many come in a variety of flavors such as menthol, vanilla, orange, apple, cola, chocolate, cherry, coffee, and grape. History Tobacco use has been documented for over 8,000 years. Tobacco cultivation likely began in 5000 BC with the development of maize-based agriculture in Central Mexico. Radiocarbon methods have established the remains of cultivated and wild tobacco in the High Rolls Cave in New Mexico from 1400 – 1000 BC. #tobacco #animation #video #explanation #medical #biology #musawir #whiteboard
