Imperial Tobacco Company review: Lambert & Butler silver original cigarettes

Since stopping smoking 11 months ago, I have had severe, life changing mouth and throat ulcers which has been capacitating as unable to eat, drink, talk and sleep. I have been on all the steroid treatments and every ulcer treatment on the market and the only thing that eases them is for me to continue smoking 3-5 cigarettes a day which is dreadful. I have emailed the company asking what ingredients/toxins are in these dreadful killers but had no response. My Consultant is also at a dead end. Please can someone help to identify what is making this happen. I really need some help as cannot continue like this and have no desire to continue smoking.
