Experimental research shows fecal transplant reduces nicotine withdrawal severity, suggesting gut-brain interactions play a key role.
Our results indicate that under our experimental conditions fecal transplant can reduce the severity of nicotine withdrawal. This suggests that interactions along the gut-brain axis are important for the development of nicotine dependence and might help lower the risk of cancer and other serious health problems in humans.
