One of the conditions brought about by smoking is emphysema, which is a prominent feature of COPD. The idea of including activated charcoal in cigarettes is to reduce the infections. The smoke is less harmful to the smoker than when there would have been fiber filters. The result is a cloud of smooth and flavorsome smoke. The use of activated charcoal filters does not affect the draw than when standard fibers are used. As smoke passes through, the charcoal absorbs the toxins without affecting the flavor or the draw. Two thin fiber filters are included in a cigarette to hold the layer of activated carbon at the center. When charcoal filters are included in cigarettes, it reduces the ciliary depressant activity of the smoke.Īctivated charcoal acts as an adsorbent in the cigarettes because of the high specific surface area. These elements have been determined to cause irritation and other biological changes in human tissues. Additionally, cigarettes with activated charcoal filters eliminate nicotine and carbon monoxide from the smoke. Activated charcoal adsorbs different toxins, including formaldehyde, hydrogen cyanide, crotonaldehyde, and ammonia. The aim of including the activated charcoal in the filters is to absorb the gas phase toxins in the mainstream smoke. Most cigarette brands contain activated carbon granules fixed in the filter. Activated charcoal is shown in the figure below. The elements do not become part of the carbon but only stick on the surface. The process through which carbon reduces the elements from the smoke is referred to as adsorption. The body's inability to be absorbed makes it effective as this prevents the side effects that cigarette smokers would have when the activated charcoal is absorbed into the body. The toxins and molecules that are bound to it can be eliminated out of the body through feces. One crucial element in cigarette manufacture is that the body does not absorb the activated carbon in the filters. Again, activated charcoal has a negative electric charge making it effective in attracting the positively charged molecules present in the smoke. The increased surface area makes it effective in trapping chemicals and toxins. Activated charcoal is processed under high temperatures to make it porous.
