What body system is most affected by vaping?

The respiratory system is most affected by vaping because the act of inhaling vaporized substances directly impacts the lungs and airways. Vaping introduces harmful chemicals, including nicotine and various toxins, into the respiratory tract. This can lead to inflammation, decreased lung function, and other respiratory issues such as bronchitis, asthma exacerbation, and various forms of lung damage.

While there may be some effects on the circulatory system, as the nicotine from vaping can influence heart rate and blood pressure, the primary impact of vaping is on the respiratory system due to the direct inhalation of harmful substances. The digestive system and nervous system can experience indirect effects, but the lungs and respiratory processes face the most immediate and significant consequences from vaping.
