to all you thinking of quiting dont hesitate listen to your body dont think like i did and think it wont happen to you. i had a heart attack 16 months ago and quit smoking that day. keep smoking and it will get you one day maybe not today maybe not tomorrow but it will. there is no doubt in my mind that it is a very poisonous drug and our government should remove it from sale. since november 2011 my life has been bad with not only myself having a heart attack but my mother who suffered a stroke at the age of 72 probably from her smoking. it left her with some brain damage , she now lives in a nursing home with a bit of vascular dementia and has much difficaltly walking. so please if you smoke stop now . GOOD LUCK TO YOU ALL.
