Question

Is a substance in tabaco smoke that reduces the blood’s ability to carry oxygen

Answer 1

Yes, carbon monoxide is a substance in tobacco smoke that reduces the blood's ability to carry oxygen. When a person inhales tobacco smoke, carbon monoxide is absorbed into the bloodstream, where it binds to red blood cells more readily than oxygen does. This reduces the amount of oxygen that can be transported by the blood, leading to decreased oxygen levels in the body.
