The Study
Smokeless Nicotine Exposure Has No Lasting Effect on Fasting or Postglucose Circulation Leptin in Young Rats
This study just watched what happened to some baby rats after giving them nicotine or sugar pellets, and saw that their leptin levels didn’t change. But we don’t know if the groups were picked fairly or if the scientists were careful — so we can’t say nicotine really didn’t do anything, just that they didn’t see a change in this one small group.
Analysis score

Groups of people are followed over time to see who develops an outcome. Strong for identifying risk factors and associations, but cannot prove causation as firmly as RCTs.
Key takeaways
Summary
Based on the study abstract and findings.
