"Charcoal" Filter Cigarettes
As a ciggy smoker, one of the casuals at work today, offered me a charcoal filter cigerette (Winfield Gold), i still got the full effects from smoking less of that chemical taste about it!:D

Effect of charcoal containing cigarette filters on gas phase VOCs
Liqin Zhang, MS, Bryan A. Hearn, Christina L. Vaughan, Ameer D. Tavakoli, Gregory M. Polzin, Clifford H. Watson, and David L. Ashley, PhD. National Center for Environmental Health, Division of Laboratory Sciences, Centers for Disease Control and Prevention, 4770 Buford Highway, NE, Atlanta, GA 30341

Objective: The recent introduction of activated charcoal containing filters on a major name-brand cigarette has generated renewed interest as a means to reduce selected volatile organic compounds (VOC) in mainstream smoke. Inclusion of activated charcoal in cigarette filters is not a new design feature since several commercial brands that contain charcoal containing filters are already being sold in the United States, but they all have a relatively small market share. In other countries, such as Japan, activated charcoal containing cigarettes filter are more popular. The mainstream smoke delivery levels of selected compounds may be affected by this introduction of charcoal.

Methods: We measured selected physical properties and mainstream smoke mainstream smoke deliveries of tar, nicotine, and carbon monoxide (CO), volatile organic compounds (VOCs), tobacco specific nitrosamines (TSNAs), polyaromatic hydrocarbons (PAHs), and selected phenolic compounds in the mainstream smoke from newly introduced brands and from existing brands that contain charcoal.

Results: The inclusion of charcoal in the filter resulted in a significant reduction of selected volatile chemicals in machine-generated mainstream smoke compared to the more traditional cellulose acetate filter. The amount of reduction was dependent on the type and length of filter. However, little or no reduction was observed for other harmful compounds such as benzo[a]pyrene, NNN, and NNK.

Charcoal cigarette filters and lung cancer risk in Aichi Perfecta- Japan


The lung cancer mortality rate has been lower in Japan than in the United States for several decades. We hypothesized that this difference is due to the Japanese preference for cigarettes with charcoal- containing cigarettes...........

Cigarettes with defective filters marketed for 40 years: what Philip Morris never told smokers


Background: More than 90% of the cigarettes sold worldwide have a filter. Nearly all filters consist of a rod of numerous ( > 12 000) plastic-like cellulose acetate fibres. During high speed cigarette manufacturing procedures, fragments of cellulose acetate that form the mouthpiece of a filter rod become separated from the filter at the end face. The cut surface of the filter of nearly all cigarettes has these fragments. In smoking a cigarette in the usual manner, some of these fragments are released during puffing. In addition to the cellulose acetate fragments, carbon particles are released also from some cigarette brands that have a charcoal filter. Cigarettes with filters that release cellulose acetate or carbon particles during normal smoking conditions are defective.

Objective: Specific goals were to review systematically the writings of tobacco companies to: (a) identify papers that would document the existence of defective filters; (b) characterise the extent of the defect; (c) establish when the defect became known; (d) determine whether the defect exists on cigarettes marketed currently; (e) assess the prevalence of the defect on cigarettes manufactured by different companies; (f) define whether the knowledge of the defect had been withheld by the tobacco company as confidential and not disclosed publicly; and (g) ascertain the feasibility of correcting or preventing the defect.

Methods: Document searches utilised databases of the scientific literature, medical journals, chemical abstracts, US Patents, Tobacco Abstracts, papers presented at tobacco meetings and court documents.

Results: Sixty one documents of Philip Morris, Inc were selected for study because they disclosed specifically the "fall-out" of cellulose acetate filter fibres and, for cigarettes with charcoal filters, carbon particles from cigarette filters. The term "fall-out" was defined in 1985 laboratory protocols of Philip Morris, Inc. as "loose fibers (or particles) that are drawn out of the filter during puffing of the cigarette". As early as 1957, the health concern of inhaling cellulose acetate fibres released from cigarette filters was addressed by Philip Morris, Inc. A 1962 document reported the results of laboratory tests conducted by Phillip Morris, Inc that compared the "fall-out" of cellulose acetate fibres from the filters of their cigarettes (Marlboro) and cigarettes of their competitor (Liggett & Meyers). A 1997 overview by Phillip Morris of documents addressing the "fallout of carbon particles and cellulose acetate fibers from filters" stated that they were "essentially routine reports" of cigarette filter assays, and referenced a "Filter Fallout" memo written in 1961—more than 40 years ago. Most likely these tests are being conducted presently as illustrated by a 1999 report that details the revisions of the "fall-out" protocol of Phillip Morris, Inc and reports the results of tests that measured the discharge of cellulose acetate fibres and silica gel from beta cigarettes with a new type of filter. Our analysis of the "fall-out" tests results presented in the 61 "fall-out" documents showed that filter fibres and carbon particles were discharged from the filters of all types of cigarettes tested. These cigarette types (n = 130) included both coded cigarettes and popular brand name cigarettes. No publications were found in the scientific literature of the "fall-out" studies. Thus, the results of the "fall-out" studies are thought to have been withheld as confidential to Philip Morris, Inc. We have identified also other companies that have tested recently cigarettes for defective filters. In addition, our searches have shown that simple, expedient, and inexpensive technologies for decontaminating cigarette filters of loose cellulose acetate fibres and particles from the cut surface of the filter have been developed and described in 1997 and 1998 US patents. What is more important is that these patents also define methods for preventing or reducing the broken plastic-like fibres that arise during cigarette making. Many US patents (n = 607; 1957 to 2001) have been awarded for cigarette filters. Some of these inventions describe novel materials and unique filtration schemes that would eliminate or minimise the discharge of filter materials into mainstream smoke.

Conclusions: We have shown that: (a) the filter of today's cigarette is defective; (b) Philip Morris, Inc has known of this filter defect for more than 40 years; (c) the existence of this filter defect has been confirmed by others in independent studies; (d) many methods exist to prevent and correct the filter defect, but have not been implemented; and (e) results of investigations substantiating defective filters have been concealed from the smoker and the health community. The tobacco industry has been negligent in not performing toxicological examinations and other studies to assess the human health risks associated with regularly ingesting and inhaling non-degradable, toxin coated cellulose acetate fragments and carbon microparticles and possibly other components that are released from conventional cigarette filters during normal smoking. The rationale for harm assessment is supported by the results of consumer surveys that have shown that the ingestion or inhalation of cigarette filter fibres are a health concern to nearly all smokers.

So what you're doing is poisoning the 2nd hand smokers more than yourself.



Natural American Spirit is a brand of cigarette and tobacco products manufactured in the United States by the Santa Fe Natural Tobacco Company. The company was founded in 1982, but in 2002 was acquired by Reynolds American and is now an official subsidiary.

Their products are marketed as being "100% Additive-Free Tobacco", though the company warns that they are as hazardous as other cigarettes and openly dissuades others from taking up smoking. This was part of an FTC ruling and agreement stemming from allegations that the advertisement of additive-free cigarettes made consumers feel that the product might be less addictive than regular cigarettes

I buy mine from a local deli, maybe you should look into your deli to order you a carton.

Why not just grow your own tobacco? Then you have a truly organic, additive free, high quality smoke to begin with.
