Regular cigarette smoking can cause harm to almost every body organ and lead to illnesses like cancer and respiratory defects. Cigarettes contain carbon monoxide, nicotine, and tar which can raise heart rate and blood pressure, coat the lungs in tar, and deny muscles and the brain of oxygen over time. This can result in health issues like lung disease, heart failure, and stroke. Electronic cigarettes provide a healthier alternative, as they contain liquid nicotine that is vaporized rather than burned, avoiding harm to the user and others nearby. Users still get the nicotine effect quickly but can gradually reduce nicotine levels to help quit smoking entirely. Electronic cigarettes better simulate the smoking experience and are recommended over regular cigarettes.
