What are the health risks of nicotine?

The health risks of nicotine are notably significant, especially when consumed through traditional methods such as smoking, vaping, dipping, or snuffing. These methods are associated with severe health consequences, including increased cancer risks (like mouth and nasal cancers), cardiovascular issues such as heart attacks and strokes, and peripheral vascular diseases. Nicotine is also known to cause cognitive decline due to the damaging effects on endothelial cells, which are crucial for nutrient delivery throughout the body and brain 1.

While nicotine itself is not directly carcinogenic, its mode of consumption often leads to cancer, particularly when smoked or taken through forms that lead to exposure of mucosal tissues to carcinogens. Nicotine is a powerful cognitive enhancer in the short term, enhancing focus and alertness, yet it poses risks like increased blood pressure and vasoconstriction, which are unhealthy for the body 2.

For younger individuals, the risks are exacerbated due to the potential for addiction and interference with natural brain development. It is highly addictive and can lead to dependence, which is particularly concerning for adolescents who may use it initially for cognitive enhancement under peer influence, facilitated by targeted marketing strategies 3 4.

Overall, despite any short-term cognitive benefits, the long-term health risks associated with nicotine consumption, especially through harmful delivery methods, significantly outweigh these temporary advantages 5 6.
