Yes, it's true. Additives commonly found in any manufactured product can be found in tobacco also. There's more to cigarettes besides just tobacco!! And if you don't beleive us, take a look at the list below at more than 600 of the ingredients found in cigarettes in the USA. If you doubt the authenticity of this list, take a look at UK's Dept. of Health list "Permitted additives to Tobacco products in the UK (2003)"
It begs the question as to why manufacturers would want to use such ingredients in their products.
