The Cigarette Ingredients Big Tobacco Doesn’t Want You to Know

There’s a reason smoking is so hard to quit; cigarettes are packed with a shocking number of highly addictive chemicals like these.

Tobacco smoke is a complex chemical mixture containing up to 4,800 combustion products, 2,000 of which are known to be toxic substances. Fully 90 individual substances in tobacco smoke have been classified as carcinogenic. What’s more, many of these chemicals are included to amplify nicotine addiction, or to offset unpleasant smells and tastes. Here’s a sample of what smokers take in their lungs and blood vessels with each puff.

Sugar amplifies your addiction.

It sounds innocuous enough, but burning sugar produces acetaldehyde, which accelerates and amplifies the addictive effect of nicotine.

When cocoa burns, it becomes bromine and enlarges the bronchial tubes, so more nicotine can be inhaled more deeply. (Licorice has the same effect.)

Menthol reduces the sensation of irritation and pain.

It also calms the bronchial tubes and expands them, resulting in deeper inhalation without any unpleasant feeling or burning sensation. Menthol also masks the pungent taste and makes smoke feel cooler and fresher. All cigarette brands today make use of menthol additives even in normal cigarettes, which helps recruit young “replacement smokers” by making inhalation easy for them.

“Light” cigarettes are just as hazardous.

“Light” cigarettes are just as hazardous.
Early studies at the beginning of the 1970s showed that if smoke is diluted with extra air, as light cigarettes are, an addicted smoker merely takes deeper and stronger puffs. So without even realizing it, “light” smokers achieve exactly the same nicotine level as when previously smoking normal cigarettes. For almost 30 years, “lights” stopped many smokers from quitting, as they believed the cigarettes were allegedly healthier and less damaging. The United States and EU have now banned terms such as “mild,” “low tar,” “light,” “ultra light,” and “ultra” from continuing to deceive the consumer.

This can be used to change the tobacco's pH value to be less acidic and more basic, allowing more nicotine to be released. When nicotine reaches the brain receptors more quickly it provides a better kick, which leads to more severe addiction (and also helps explain why one brand “tastes” better than another). Research documents confirm that the cigarette industry has known this science since 1962.

This substance takes the edge off the tobacco flavor and reinforces nicotine binding with the receptors in the brain by some 30 percent.

One of the industry’s major marketing challenges was the recent evolution of militant anti-smokers bothered by smoke who fought to ban smoking. This led the tobacco industry to research how it could reduce irritation and visibility of smoke and improve its smell to minimize these complaints. There are some 300 industry patents for these additives alone. Among those for a better smell include: acetylpyrazine, anethole, betacaryophyllene, cedrol, ethyl 3-methylvalerate, furaneol, limonene, p-anisaldehyde, phenethyl alcohol, “Aromatek 150,” and “Aromatek 245.”

These include such cryptic names as:  aluminium sulfate, (NH4)2So4, NaH2Po4, “XLF-636,” “XLF-662,” “XLF-680,” and “XLF-755.”

By reducing the conspicuousness of smoke, cigarette makers hope to make smoking more socially acceptable. These chemicals include: alumina sol-gel, MgCo3 sol-gel, MgCo3, H3Po4, K2P2O7, CaCo3, calcium carbonate, Na2Co3 (sodium carbonate), calcium chloride, citric acid, magnesium oxide, potassium acetate, potassium citrate, sodium hexametaphosphate, glutaric acid, hydromagnesite, malonic acid, potassium phosphate, magnesite, potassium succinate, magnesium carbonate, monobasic potassium phosphate, calcium carbonate, monopotassium phosphate, “Studio 26 blend,” and “XTH Studio blend.”
