The relationship between stimulants and cancer risk is complex and varies depending on the type of stimulant. For instance, the link between nicotine and cancer is well-established. Nicotine, primarily consumed through smoking, is a major risk factor for lung cancer and other types of cancers, such as oral, esophageal, and bladder cancer. On the other hand, the impact of caffeine on cancer risk is less clear, with some studies suggesting a potential protective effect against certain cancers, such as liver and colorectal cancer.
