Smoking introduces thousands of harmful chemicals into the body, many of which are carcinogenic and toxic to cells. At the cellular level, these substances damage DNA, disrupt normal cell cycles, and impair the body's natural repair mechanisms. For example, chemicals like benzene and formaldehyde can cause mutations in genes that regulate cell growth, leading to uncontrolled cell division and cancer. Smoking also increases oxidative stress, causing the release of free radicals that damage cell membranes, proteins, and mitochondria. Over time, these cellular disruptions contribute to serious health issues such as cancer, cardiovascular disease, and respiratory conditions like COPD.
