The study of nicotine metabolism shows that nicotine has a half-life of 60 to 90 min, and that nicotine concentration in human breast milk is 2.9 times higher than in the plasma. Smokers are less likely to choose breastfeeding. The duration of breastfeeding is shorter and there is less milk production amongst smokers who decide to breastfeed. Breastfeeding diminishes the infant's respiratory problems that are linked to smoking. During the breastfeeding period, in addition to psychological support, nicotine replacement therapy should be proposed, preferring gums or 2 mg tablets with a short half-life taken after feeding. For those who continue to smoke, the number of cigarettes should be limited and smoking should be done after feeding and outside of living quarters.
尼古丁代谢研究表明，尼古丁的半衰期为60至90分钟，人母乳中的尼古丁浓度比血浆中高2.9倍。吸烟者选择母乳喂养的可能性较小。母乳喂养的持续时间较短，决定母乳喂养的吸烟者产奶量也较少。母乳喂养可减少婴儿与吸烟相关的呼吸问题。在母乳喂养期间，除了给予心理支持外，还应建议进行尼古丁替代疗法，优先选择口香糖或半衰期短的2毫克片剂，在喂奶后服用。对于继续吸烟的人，应限制吸烟数量，且应在喂奶后并在居住场所外吸烟。
