Electronic cigarettes also known as electronic nicotine delivery systems are devices that heat a liquid containing nicotine, flavorings, and other chemicals, and produce an aerosol that users inhale. E-cigs are often marketed as a safer alternative to smoking, but they are not harmless. Vaping may increase the risk of lung cancer and other lung diseases.

One of the reasons why vapes are harmful is that they contain many chemicals that can cause cancer. These include formaldehyde, acetaldehyde, acrolein, and heavy metals, such as lead, nickel, and chromium. These chemicals can damage the DNA of the lungs' cells, making them more likely to grow abnormally and form tumors.
Another reason why e-cigarettes are harmful is that they can cause inflammation and injury in the lungs. E-cigarettes can irritate the lining of the airways and alveoli, the tiny sacs where gas exchange occurs. This can lead to coughing, wheezing, shortness of breath, and chronic obstructive pulmonary disease (COPD). E-cigarettes can also impair the immune system and make the lungs more vulnerable to infections, such as pneumonia and bronchitis.
E-cigarettes are hazardous for young people, who are more susceptible to the effects of nicotine and other chemicals. Nicotine can harm the brain development of teenagers and affect their memory, attention, and learning. Nicotine can also increase the risk of addiction to other substances, such as alcohol and drugs. E-cigarettes can also expose young people to secondhand emissions, which can have similar health risks as the aerosol inhaled by the users.
The bottom line is that e-cigarettes are not safe and can cause lung cancer and other lung diseases. The best way to protect your lungs and your health is to quit smoking and vaping altogether.
