Hey Twila, I'm not trying to encourage you to go back to the dreaded weed or anything, but as well as the delights of nicotine, carbon monoxide and tar, those lovely coffin nails also contain other surprises, such as:
Acetone, more commonly used in nail polish remover.
Ammonia, used in the dry cleaning industry.
Arsenic, a deadly poison used in pest control and insecticides.
Benzene, a cancer-causing agent used in the production of fuel and chemicals.
Cadmium, a very poisonous chemical that can cause liver, kidney and brain damage, used in batteries.
Formaldehyde, a known carcinogen used to preserve dead bodies.
Now hand me that lighter ...
