### output:

Apart from area nut, rajnigandha contains several toxic and harmful chemicals such as Eugenol, N-Nitrosamines, Sodium Carbonate, Ammonium Carbonate, Ammonia, etc. Apart from these, they contain high levels of heavy metals such as lead, arsenic that cause cancer, organ failure, and various nervous diseases. The Indian Institute of Environmental Medicine estimates that on an average, tobacco contains at least 19 known carcinogens and at least 30 metallic compounds comprising heavy metals. Further, the Cancer Tobacco Research Institute (affiliate of the Indian Council of Agricultural Research) estimates that the popular brands of Gurkha and pan masala, such as Manichean, Rajnigandha, Chain Chain etc., contain nicotine. Gutkha, or chewing tobacco, is a known carcinogen, and it is known to cause oral cancer and cancer of the esophagus, pharynx, larynx, stomach, and pancreas. Apart from cancer, tobacco also results in various health problems such as Gum Disease, Peripheral Vascular Disease, Hypertension, Peptic Ulcer Disease, and Coronary Artery Disease.
