People have been saying this for the past 15-20 years, yet it keeps not being true. The difference is pretty obvious with just a little thought. Sugars are part of a balanced diet, it's perfectly healthy to consume some amount of sugars during a normal day. Cigarettes have NO health benefits, they only serve to kill you. Cutting out all cigarettes is a pretty minimal sacrifice compared to avoiding large swaths of foodstuffs.
Comparing the two only makes normal people rolls their eyes at you and ignore anything you have to say from your ivory tower.
