It supports smoking cessation by mimicking mild nicotine effects while blocking nicotine from binding to receptors. Often explored as a potential aid in behavioral therapy programs for long-term abstinence. Also under investigation for cognitive enhancement and mood regulation due to its action on central nervous system pathways.
