Famous People Smoking

The common name for the remains of a cigarette after smoking is a cigarette butt. The butt typically comprises about 30 percent of the cigarette's original length. It consists of a tissue tube which holds a filter and some remains of tobacco mixed with ash. Cigarette butts are the most numerically frequent litter in the world. Cigarette butts accumulate outside of buildings, on parking lots, and streets where they can be transported through storm drains to streams, rivers, and beaches.
Cigarette litter
Cigarette filters are made from cellulose acetate and are biodegradable, though depending on environmental conditions they can be resistant to degradation. Accordingly, the duration of the degradation process is cited as taking as little as one month to three years to as long as 10 to 15 years. One campaign group has suggested they are never fully biodegraded.
