Here's a list of the 10 most dangerous:



- Ammonia -- used to increase the absorption rate of nicotine. It's also used to clean your toilet, helps to treat waste water (poop and pee) and is a key ingredient in liquid fertilizer.
- Arsenic -- used as a pesticide on tobacco plants, it remains in the resulting cigarette. If you have a rat problem in your home, you can use arsenic to kill them.
- Cadmium -- a metallic compound that tobacco collects from acidic soil. Is the battery in your cell phone low? Use cadmium to recharge it!
- Formaldehyde -- a byproduct of cigarette smoke, this colorless gas is commonly used to preserve dead bodies for burial.
- Acetone -- another byproduct from burning a cigarette. It's also found in nail polish remover and, like ammonia, is used to clean toilets.
- Butane -- this byproduct is also used to help you light your cigarette, in the form of lighter fluid.
- Propylene Glycol -- added to cigarettes to keep tobacco from drying out. What it really does is speed up the delivery of nicotine to the brain.
- Turpentine -- used to flavor menthol cigarettes. This oil also can be used to thin paint and strip varnish from wood.
- Benzene -- another byproduct from burning a cigarette. You can find benzene in pesticides and gasoline.
- Lead and Nickel -- Yes, these are metals. Need we say more?
