Toxic cigarette butts used to repair steel corrosion

Chinese scientists have found that chemical extracts from cigarette butts can be used to protect steel pipes from rusting.

These extracts are reportedly so toxic they kill fish.

This is possible good news for the oil industry that apparently spends millions to repair the corrosion of steel pipes. But it might make some smokers think twice.

China is the world's largest smoking nation and has been trying to find a way to recycle cigarette butts that often find their way into the environment.

The study appears in the American Chemical Society's bi-weekly journal.
