What is the relationship between nicotine and carbon monoxide?

Nicotine and carbon monoxide are both harmful substances found in tobacco smoke. Nicotine is an addictive chemical that stimulates the central nervous system, leading to dependence and various health issues. Carbon monoxide, a toxic gas produced during the combustion of tobacco, reduces the blood's ability to carry oxygen, leading to cardiovascular problems. Together, they contribute to the overall harmful effects of smoking on health.
