Date :Note :
Mostly from tobacco varieties of high nicotine content and specifically grown for this purpose (nearly always nicotiana rustica) but also from waste products of the tobacco industry, from tobacco liquors in Virginia cigar production, etc. The greater the ballast of the nicotine-containing substance the more uneconomic will the yield be. Nicotine is obtained industrially by water vapour distillation from tobacco or tobacco waste as the cheaper method of production after the tobacco or waste has been mixed with calcium oxide (quick lime). Nicotine is the raw material not only for the production of pesticides but also for medical preparations.
