Smoking has long been a part of human culture, but modern science has revealed its true dangers. Cigarettes are not just nicotine sources; they deliver a toxic mix of chemicals, causing serious health issues. This article highlights some of these harmful substances and their impact.

**Cadmium:** A heavy metal used in batteries, cadmium is highly toxic and can cause kidney damage. “Inhaling cadmium from cigarette smoke leads to its accumulation in the body, posing significant health risks.”

**Butane and Methane:** Butane, found in lighter fluid, and methane, commonly in sewer gas, are both present in cigarettes. Butane can cause respiratory issues, while methane contributes to the harmful gases smokers inhale.

**Arsenic and Ammonia:** Arsenic, a known poison, can cause cancer and cardiovascular diseases. Ammonia, used in household cleaners, “enhances nicotine absorption” but irritates the respiratory system.

**Other Chemicals:** Cigarettes also contain methanol (rocket fuel), hexamine (barbecue lighters), stearic acid (candle wax), acetic acid (vinegar), and toluene (industrial solvent). All contribute to the toxic cocktail inhaled by smokers.

**Health Impact:** Smoking damages nearly every organ in the body, leading to cancer, heart disease, and respiratory illnesses, ultimately reducing life expectancy. Secondhand and thirdhand smoke pose additional dangers to non-smokers.
