Toxic influence of cigarette and bidi smoking on carboxyhaemoglobin levels of the blood of regular smokers was compared and no significant difference was observed in both of them. A py- rolysed tobacco product, used in India as a dentifrice, when administered to rats, showed activity comparable to benzo(a)pyrene, a potent carcinogen.

Habitual consumption of betel quid containing tobacco shows a strong cy- totoxic potential.

Nicotiana rustica Linn. is known as Kalakatiyaa or Vfilaayati tobacco. Its nicotine content is high and is not suitable for cigarettes, cigars or bidis. Different variants of this tobacco are used for hookah, chewing and snuff.
