I have never heard of nasal snuff! Could you explain what this is?
I do agree that smokeless tobacco is a safer alternative to smoking tobacco as far as lung cancer is concerned, but what about the increased risk of mouth and throat cancer that smokeless tobacco users have? We aren't saying that one cancer is "better" than the other, but that they all contain cancer-causing agents and are harmful when used. There is no safe way to use tobacco products.
NRT (Nicotine-replacement therapy), including gum, patch, inhalers, etc., do NOT contain any cancer-causing agents, and are a safer method of quitting smoking.
