Cigarettes used to come in reeds or tubes when they were first discovered in Central America and Mexico in the 9th century. Today, cigarettes come in small, cylindrical tubes with a stiff filter on one end.
Cigarettes from long ago were made from very few ingredients. Whereas now, most cigarettes are made from various materials. Those present in cigarette smoke alone are different from those inside the actual cigarette filling.
Cigarette smoke exits the cigarette stick in two ways. One is from the end that you light up, and the other is the filter tip that touches the smoker’s lips. Some of the elements that enter the smoker’s body are carbon monoxide, tar, and nicotine.
Aside from those toxic elements, there are still an estimated 60 other chemicals in a cigarette’s smoke. These include formaldehyde, aromatic metals, and more, which can harm the body.
