Smoking

According to a Report of the Surgeon General, smoking is the leading cause of preventable disease, disability and death in the U.S. It can cause cancer, heart disease, stroke, lung diseases, diabetes, and chronic obstructive pulmonary disease (COPD), which includes emphysema and chronic bronchitis. Smoking can also increase the risk of tuberculosis, certain eye diseases, and problems of the immune system, including rheumatoid arthritis.

Vaping devices

Although vapes are relatively new products, and the long-term effects are not yet known, we do know that nicotine can harm adolescent brain development. And the dangerous chemicals which vapes produce can lead to lung injury, COPD and may cause asthma and lung cancer.

Chewing tobacco

Smokeless tobacco products aren't linked to lung cancer like their inhaled counterparts, but there are other conditions users are at risk of developing. These products can contain carcinogens and may cause gum disease, tooth decay, tooth loss, and can lead to several types of cancer including mouth, esophageal, and pancreatic.
