Hi.. Welcome to HEALTHCARE MAGIC.. I have gone through your query and can understand your concerns.. As per your complain in case if your son is addicted to chewing tobacco, the first thing that you need to do is to keep patience and do not get harsh with him otherwise he will become resistant.. You should counsel and reassure him that tobacco is bad for health and can even cause mouth cancer.. You can also take him to an Addiction Medicine Specialist and they can do a proper counselling and also advise him Nicotine Replacement Therapy in the form of Nicotine skin patches and chewing gums that will help in maintaining blood levels of nicotine and will reduce the urge to chew tobacco.. Chewing sunflower seeds and other hard chewables can also reduce the urge to chew tobacco.. Also keep him away from bad company as they can encourage him to re-do the harmful things.. Keep in engaged in more of recreational activities and leisures of his choice.. Encourage him to make a good future.. Be friendly with him and not being stubborn or strict.. Hope this information helps.. Thanks and regards. Dr.Honey Nandwani Arora.
