What is one reason nicotine nasal sprays may be used in cessation therapy?

Nicotine nasal sprays are effective in cessation therapy primarily because they deliver nicotine quickly to the bloodstream. This rapid absorption of nicotine provides immediate relief from withdrawal symptoms and cravings associated with quitting smoking. By mimicking the fast-acting effects of smoking, the nasal spray can help ease the transition away from tobacco use, making it a valuable tool for individuals attempting to quit.

The other options do not provide the same level of evidence-based support for the efficacy of nicotine nasal sprays in cessation therapy. While some may argue about flavor-enhancement or customization, these factors do not contribute to the core mechanism of action that assists smokers in quitting. The focus should remain on the rapid delivery system which is crucial for managing cravings effectively during the quitting process.
