Which nicotine replacement therapy has the quickest absorption rate?

Nicotine nasal spray is noted for its rapid absorption rate because it delivers nicotine directly into the bloodstream through the nasal mucosa. This method allows for quick onset of effects, typically within a few minutes, which can be particularly beneficial for individuals experiencing strong cravings for nicotine.

The nasal spray allows the nicotine to bypass the digestive system, avoiding a slower absorption process typically seen with other forms of nicotine replacement therapies. This immediate effect can help users manage their cravings more effectively in moments of need.

In contrast, other forms such as gum, inhalers, or lozenges may take longer for nicotine to be absorbed into the bloodstream, as they often require the body to process the nicotine through different pathways, ultimately leading to a delayed response in alleviating cravings.
