In a list provided by the American Lung Association on their website, here are some more examples of just a few chemicals that are added to cigarettes: acetone which is found in nail polish remover, arsenic which is used in rat poison, benzene which is found in rubber cement, butane which is used in lighter fluid, cadmium which is an active component in battery acid, lead which is used in batteries, methanol which is a main component in rocket fuel, nicotine which is used as an insecticide, tar which is a material for paving roads and toluene which is used to manufacture paint
The same goes for bundle purchases, new arrivals, and, of course, any item with a "Free Shipping" banner on the picture
Slogan: "Low Tar / Camel Taste"
There is minimal price difference, so the choice comes down to personal taste preference and availability
