Nicotine fingers are a common side effect of smoking. They are characterized by yellowish-brown stains on the fingertips and nails, caused by the absorption of nicotine through the skin.
The stains are difficult to remove and can be embarrassing for some smokers.
Although they are not harmful in themselves, they are a visible reminder of the negative impact smoking has on the body.
Nicotine fingers are not a unique symptom of smoking, as other substances like tea, coffee, and certain medications can also cause similar staining.
However, smoking is the most common cause, and the stains are usually more pronounced in smokers.
If you are concerned about nicotine fingers, quitting smoking is the best way to prevent them.
There are also products available that can help reduce the appearance of nicotine stains, such as nail polish removers and bleaching agents.
