  • Cause disturbed sleep with higher nicotine exposure because nicotine is a stimulant7
  • May increase the risk of SIDS by affecting the way a baby can resuscitate during hypoxic episodes (when the body doesn't have plenty oxygen)8
  • Interfere with normal infant lung evolution (Lactmed, 2020)
  • Reduce prolactin levels (a hormone needed for making breast milk) and and so affect milk supply although non all studies agree ix.
  • Be a hazard factor for childhood obesity and thyroid dysfunctionten eleven.

The removal of nicotine from the list of drugs contra-indicated during lactation does not diminish the need for more research on the effects of smoking during lactation.

cigarette smoke is a complex mixture of chemicals with ~4000 compounds, including >60 carcinogens. Whether compounds other than nicotine and cotonine [a metabolite of nicotine] are transferred to human being milk with similar fourth dimension courses and, if and so, what levels are transmitted remain unknown.

It is not clear whether there comes a time when a certain number of cigarettes smoked and hence the amount of nicotine and other substances crossing into milk could outweigh the benefits of breast milk.

This means that nicotine levels in breast milk will have fallen by one-half after near one and a one-half to two hours afterward the female parent finishes her cigarette. Based on the general guide that it takes five half lives to clear a substance from the body information technology may take about 10 hours for nicotine to completely leave the mother's claret or breast milk after one cigarette. In practise although nicotine isn't stored in breast milk, the levels of nicotine in a female parent who smokes regularly throughout the day will accumulate over 24 hours with each cigarette she smokes and breakdown products of nicotine e.g. cotonine remain for much longer.xvi Benowitz et al explain:

smoking represents a multiple dosing state of affairs with considerable aggregating while smoking and persistent levels for 24 h of each day.

The authors signal out that babies take much longer than adults to eliminate (metabolise) nicotine and cotinine from their bodies.
