"than cigarettes made from tobacco alone."

What percentage of cig's smoked are made from tobacco alone and don't include Benzine, Ammonia, Formaldehyde, Acetone, Nicotine, Carbon Monoxide, Rat Poison, Cyanide.

We legally allow companies to add this sh!t to smokes and peddle them to the masses but we ban a chemical free natural plant with no additives?
