Which substance is the number one preventable cause of death in the US?

• A. Illicit drugs
• B. Tobacco
• C. Alcohol
• D. Prescription misuse

Answer: (B)

Tobacco use is the leading preventable cause of death in the United States because it’s tied to a wide range of deadly diseases—most notably lung cancer, heart disease, stroke, and chronic obstructive pulmonary disease—and millions of people use tobacco over time. The risk builds with how long and how intensely someone smokes, so the overall toll is very large. Quitting reduces risk pretty quickly for heart and circulation, and long-term risk declines with time, but some risk remains higher for those with a long history of smoking. Other substances like illicit drugs, alcohol, or prescription misuse cause serious harm too, but tobacco accounts for more preventable deaths overall, which is why it’s identified as the top preventable killer.
