Final answer:
Products containing nicotine can have serious health risks, including increased risks of heart disease, stroke, and different types of cancers. E-cigarettes, which contain nicotine and cancer-causing chemicals, can lead to serious lung disease and death. Secondhand smoke from tobacco products is also harmful, increasing the risk of lung cancer and heart disease in non-smokers.
Step-by-step explanation:
Products containing nicotine pose several health risks. Nicotine is highly addictive and is associated with increased risks of heart disease, stroke, and various types of cancers. It interacts with acetylcholine receptors in the central nervous system, affecting arousal and reward mechanisms. Additionally, the use of e-cigarettes, which contain nicotine and cancer-causing chemicals, has been linked to serious lung disease and death. Exposure to secondhand smoke from tobacco products also increases the risk of lung cancer and heart disease in non-smokers.
