Jonathan Bennion from the Institute of Human Anatomy highlights the alarming reality of lung cancer, revealing that smoking accounts for roughly 90% of lung cancer deaths, making it one of the most preventable cancers. Through a vivid comparison of healthy and smoker’s lungs using cadaver dissections, the video starkly illustrates how smoking transforms lung tissue from elastic and pinkish to blackened, stiff, and cancerous. Smoking, especially tobacco cigarettes, clearly remains the primary risk factor, but other forms, including cannabis and vaping, are also addressed.
When it comes to cannabis smoking, Bennion explains that the risk is less clear than with tobacco, largely due to limited research. Many existing studies struggle with bias, as cannabis users frequently also smoke tobacco, complicating efforts to isolate cannabis’s exact impact. However, Bennion emphasizes that several reports have identified cellular and molecular changes in marijuana smokers’ lung cells that closely resemble pre-cancerous alterations seen in cigarette smokers. While the exact magnitude remains uncertain, it strongly suggests cannabis smoking does elevate lung cancer risk.
Beyond lung cancer, smoking in any form negatively impacts overall health, harming bones, eyes, reproductive systems, and cardiovascular health. Bennion underscores the body’s remarkable healing capacity, noting that quitting smoking significantly reduces health risks, with notable improvements visible within just five years. Although quitting earlier is always best, it’s never too late to stop to significantly improve one’s health outcomes and quality of life.
