This is a Tobacco Plant.. It looks very similar to the Lettuce Plant. According to the Dictionary found at dictionary. com, the definition of cigarette is: :a cylindrical roll of finely cut tobacco cured for smoking, considerably smaller than most cigars and usually wrapped in thin white paper. And also the definition of 'cured' meat is : :meat which has been treated with salt and nitrate or nitrite And the 'curing of tobacco' is: It is necessary to cure tobacco after harvesting and before it can be consumed. https://en.wikipedia.org/wiki/Curing_of_tobacco And 'curing' also means: Curing (food preservation) Curing is any of various food preservation and flavoring processes of foods such as meat, fish and vegetables, by the addition of combinations of salt, nitrates, nitrites, or sugar, with the aim of drawing moisture out of the food by the process of osmosis. https://en.wikipedia.org/wiki/Curing_(food_preservation) Nitrates are: Nitrates are mainly produced for use as fertilizers in agriculture because of their high solubility and biodegradability. The main nitrate fertilizers are ammonium, sodium, potassium, and calcium salts. Several million kilograms are produced annually for this purpose https://en.wikipedia.org/wiki/Nitrate Nitrites are: Nitrate or nitrite (ingested) under conditions that result in endogenous nitrosation has been classified as "Probably carcinogenic to humans" (Group 2A) by International Agency for Research on Cancer (IARC), the specialized cancer agency of the World Health Organization (WHO) of the United Nations. https://en.wikipedia.org/wiki/Nitrite So basically what I think might be carcinogenic in 'tobacco' smoking is NOT the tobacco or cigarette itself but the Nitrates and Nitrites which might be used in curing the tobacco before it can be smoked.
