There are well over 4,000 chemicals in cigarette smoke, and some scientists will put the number as high as 7,000. Of these, about 70 are known carcinogens. One of the most highly carcinogenic substances known, aflatoxin B1, and other carcinogens, including nitrosamines, heavy metals (such as cadmium and chromium) and polycyclic aromatic hydrocarbons are examples of cancer-causing chemicals that are found in tobacco smoke.
Now, in addition to these chemicals, the tobacco industry ADDS other chemicals (additives) to cigarettes, for all kinds of reasons, some of which have been explained already in posts in this blog, and others of which you will learn about if you check this site regularly.
There are at least 599 known cigarette additives that are, or have been, used to make cigarettes more addictive, more flavourful, less irritating, more psychologically pleasing, and even to endow cigarette smoke with a more aesthetic appearance and (supposedly) a more fragrant, aromatic odour. These are just a handful of the reasons that the tobacco industry uses cigarette additives, but you can be certain that the vast majority of them have the ultimate goal of keeping smokers addicted and reducing their chances of quitting the habit.
Here’s where you will find the list of the 599 known cigarette additives:
By the way, most studies show that about three-quarters of all smokers hate the habit and want to quit, and wish they had never started smoking. That’s how powerful a grip smoking has on its victims!
