Tobacco is a plant that is grown for its leaves, which are dried and fermented before being put in tobacco products. Tobacco is the common name for several plants in the Nicotiana genus and the Solanaceae (nightshade) family, and the general term for any product made from the cured leaves of the tobacco plant. 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 around the world.
Tobacco contains the alkaloid nicotine, which is a stimulant, and harmala alkaloids. Dried tobacco leaves are mainly used for smoking in cigarettes, cigars, pipe tobacco, and flavored shisha tobacco. They can also be consumed as snuff, chewing tobacco, dipping tobacco and snus.
Tobacco use is the single greatest preventable cause of death and disease in the world. According to the World Health Organization (WHO), tobacco use is responsible for the deaths of approximately eight million people each year, with approximately 1.2 billion people being tobacco users worldwide. The WHO estimates that tobacco use causes more than five million deaths each year in developing countries, with approximately 600,000 deaths occurring in developed countries.
The use of tobacco has been linked to a number of serious health problems, including cancer, heart disease, stroke, respiratory disease, and hypertension. Smoking is the leading cause of preventable death and disease worldwide, and is responsible for approximately one in three cancer deaths in the United States.
Despite the known health risks associated with tobacco use, many people continue to use tobacco products. There are a number of reasons why people use tobacco, including the addictive nature of nicotine, social and cultural factors, and the influence of marketing and advertising by the tobacco industry.
There are a number of strategies that have been implemented to reduce tobacco use, including increasing taxes on tobacco products, implementing smoke-free policies, and providing education and support for people who want to quit smoking. The WHO has also developed the Framework Convention on Tobacco Control, which is an international treaty that aims to address the global tobacco epidemic by promoting and protecting public health.
In conclusion, tobacco use is a major public health issue that is responsible for millions of deaths worldwide. Despite the known health risks associated with tobacco use, many people continue to use tobacco products due to the addictive nature of nicotine and the influence of social and cultural factors. There are a number of strategies that have been implemented to reduce tobacco use, including increasing taxes on tobacco products, implementing smoke-free policies, and providing education and support for people who want to quit smoking.
