The Nicotine Paradox: Risks, Benefits and Future Therapeutics

Nicotine is one of the most misunderstood substances in modern science and society. For decades, its identity has been fused with the harms of smoking, overshadowing its complex biology and potential therapeutic value. This monograph aims to separate the molecule from the smoke, the science from the stigma, and the evidence from the assumptions. Across fourteen chapters, this work explores nicotine's pharmacology, cognitive effects, neuroprotective potential, mood and metabolic influences, gastrointestinal actions, cardiovascular physiology, addiction mechanisms, drug-development prospects, and ethical considerations. The goal is not to promote nicotine use, nor to minimize its risks, but to present a clear, comprehensive, evidence-based understanding of what nicotine is, what it does, and what it might become in the future of medicine. (There is a short version of each chapter, in this book, before the actual in-depth chapters)
