The common name for the remains of a cigarette after smoking is a "cigarette butt". The butt typically comprises about 30% of the cigarette's original length. It consists of a tissue tube which holds a filter and some remains of tobacco mixed with ash.
Chemical extracts from cigarette butts are so toxic that they can kill fish but can be used to protect steel pipes from rusting, a study in China has found. The chemicals, including nicotine, appear to be responsible for this anti-corrosion effect.
