EE: Smoking and Nicotine (2013)

Assessment
How long should a healthy and non-critically ill individual refrain from smoking and nicotine intake prior to an RMR measurement?
- Conclusion
  Based on the limited evidence reviewed, there is a significant acute increase in resting metabolic rate (RMR) after smoking cigarettes in healthy adults. While evidence suggests that RMR is elevated for at least 140 minutes after smoking, the length of time required for RMR to return to baseline is unknown. Additional research is needed regarding nicotine-containing products.
