Another Anti-Smoking Hoax Debunked. Those cigarette filters are 100% biodegradable.
The cigarette butt menace was created to support outdoor smoking bans because many non-smokers will accept that secondhand smoke is not harmful in an outdoor setting.
The anti-smoking zealots admit that the tobacco and paper in cigarette butts are biodegradable, but claim that the cellulose acetate cigarette filters are a plastic, like styrofoam and polystyrene, and will contaminate the earth forever. This is not true. Cellulose acetate is a wood product. It is completely degradable through biological, chemical, and photo chemical degradation mechanisms.
Sorry, I don’t have a nice, easy to read MSM news article to give you. I have research papers from cellulose acetate manufacturers. Ann W., a commentor to a Dick Puddlecote article, put me onto this. http://dickpuddlecote.blogspot.com/2011 … found.html

“STUDY OF THE ENVIRONMENTAL DEGRADATION OF CIGARETTE FILTERS: A simulation of the Roadside or Parking Lot Environment.” Stephen K. Haynes, et al,\., Research Laboratories, Eastman Chemical Company, Kingsport Tenn.
“In recent years there has been increasing public awareness of items which may be discarded as litter with particular attention being given to cigarette filters. Some studies have concluded that when cigarette filters are introduced into the environment, they either do not degrade or degrade very slowly. Previous work in our laboratories has demonstrated that cigarette filters biodegrade readily in environments where mixed microbial populations can thrive. The purpose of this study was to examine the changes occurring in cigarette filters over time in an environment similar to that of a parking lot or roadside area. In this environment, exposure to sunlight, moisture and wind occur, but there is limited exposure to microbial attack … ”
“CONCLUSIONS: Previous work has demonstrated that cigarette filters biodegrade readily in environments where mixed microbial populations can thrive. This work demonstrates that current commercial cigarette filters also degrade when exposed to an environment which is not optimal for microbial biodegradation.”
