Hello Please require you r help. My dad at 46years of age is addicted towards tobacco chewing and having couple of pans. Whenever I argue him to dump these habits. He always says that he is just chewing tobacco because he has digestive problems. At 3.00am in the night also to empty his bowel he needs to chew tobacco. He takes zandu pancharist but then too he requires tobacco. I m really really worried for his health in future. I don't know what should I do. When ever I argue with him he gets aggressive. He is literate enough and doing good with his profession but then to I don't understand how can tobacco helps him to get rid of his digestive problems. My grandfather also had these habit n he died do to cancer. I love my dad the most in these universe so Please I need you r genuine, genuine suggestion. you all r the only hope so please give your valuable feedback.
