Widely cultivated in tropical and subtropical regions. The ‘tobacco plant’ is mainly cultivated in the N.W.F.P. regions of Pakistan on a commercial scale. Tobacco is both smoked and chewed; it contains the alkaloid nicotine, a stimulant, which is harmful to the nervous and respiratory system. Also used for insecticidal purposes. The species is sometimes found as an escape.
