Tobacco consumption is known to stimulate secretion of adrenaline and noradrenaline. The component causing this could be:

1. Nicotine                                                   
2. Tannic acid
3. Curamin                                             
4. Catechin

(a) Tobacco has nicotine, which stimulates the adrenal gland to release adrenaline and
noradrenaline which in turn increases the blood pressure and heart rate, while tannic
acid is a type of polyphenol used as a mordant, curaimin, obtained from cureumin ina
pain releiver and catechine derived from catechu is an antioxidant.
