"Hey, just wanted to clear something up! Your body doesn’t actually need nicotine to survive. There are receptors in the body called acetylcholine (ACh) receptors, and nicotine can bind to them because it mimics a natural chemical your body makes called acetylcholine. But these receptors don’t need nicotine. t
They’re designed to work perfectly fine with acetylcholine, which your body produces naturally. Nicotine is just something external that happens to fit those receptors, but it’s not required for your body to function. Hope that helps!"
