Analyze the timeline of smoking cessation

Using the Smoking Cessation Timeline knowledge point

When a person quits smoking, the body begins to recover almost immediately:

• Within 8 to 12 hours: Carbon monoxide levels in the blood drop to normal, and blood oxygen levels return to normal.
• Within 1 to 9 months: Coughing and shortness of breath decrease as the lungs' cilia regain normal function.
• Within 1 year: The excess risk of coronary heart disease is halved.
• Liver health: While overall health improves, liver recovery is not a primary immediate milestone tracked in standard smoking cessation timelines.

Therefore, the benefit expected within a few hours is that blood oxygen levels return to normal.

Answer:

• (A) blood oxygen levels returned to normal (Correct answer)
• (B) risk of heart disease cut in half
• (C) improved liver health
• (D) reduced coughing and congestion
