Nicotine Patch for Long COVID or Alzheimer’s? Why Nicotine?

For decades, nicotine has been viewed primarily as a harmful and addictive substance — the main reason people become hooked on cigarettes and other tobacco products. Humans have used tobacco for over 12,000 years, whether by smoking, chewing, or sniffing it. In more recent years, pharmaceutical companies have developed nicotine patches, gums, and lozenges to help people quit smoking — all available without a prescription. However, new research is beginning to challenge this one-sided view. Scientists are now exploring whether nicotine might also offer potential therapeutic benefits. Some studies suggest it could help people suffering from long COVID or Alzheimer’s disease. This emerging perspective could change how we understand and use nicotine in modern medicine.
