According to this smoking and vaping is bad BUT nicotine can be good
>>nicotine does appear to possess some beneficial qualities. A researcher named Paul Newhouse who directs the Center for Medicine at Vanderbilt University has been examining the effects of nicotine on brain disorders for more than three decades. He and his team have conducted several studies that tested whether transdermal nicotine patches could help people with the type of memory loss that can lead to Alzheimer’s disease, and they found that nicotine significantly improved memory and attention.
The power of nicotine to improve cognition has led some intrepid biohackers to use it as a smart drug. With research suggesting the use of nicotine patches and gum can enhance vigilance, memory, and even coordination, people are starting to take the idea of nicotine supplementation seriously.
Obviously, using nicotine is not without risks. In addition to being addictive (and poisonous at high doses), nicotine has been associated with cancer, heart problems, and increased inflammation. You should consult with an expert before you consider nicotine supplementation.
