1. Remember that Quitting Is a Process Not an Event

Close to half of pregnant women who smoke either seriously consider or take steps towards stopping during pregnancy. Pregnant smokers vary in their readiness to quit and life situations and will require various interventions to cope with symptoms of withdrawal. Tailored approaches to smoking cessation take into account both the patient’s readiness to quit and other life circumstances, such as socioeconomic status, cultural backgrounds, level of social support, level of nicotine addiction, and other substance-use issues.

Motivation to quit is a dynamic factor that changes throughout pregnancy and postpartum. Factors associated with early pregnancy may influence motivation. For example:

  • NauseaWomen may lose the desire to smoke if they are experiencing nausea. However, the desire may return when this sickness has passed.
  • Not feeling pregnant Women who do not feel pregnant may be less inclined to quit or think about quitting.
  • Unplanned pregnancyWomen who have not planned to get pregnant may not have thought about quitting smoking.

For patients who find it difficult to even think about giving up tobacco, it may be helpful to suggest stopping during pregnancy or cutting down, as opposed to quitting altogether. Cutting down to fewer than 10 cigarettes per day may be a practical alternative for women who are not able to quit altogether. The “Start Thinking About Reducing Secondhand Smoke” (STARSS) program, which focuses on supporting mothers in tobacco-reduction efforts, found that when women attempt to reduce smoking, they often quit smoking or become more confident and interested in quitting smoking.

Practice Tips

  • Ask the woman questions about her smoking history and her motivations for quitting or reducing

    What is her smoking history? Has she ever tried quitting before? For how long did she quit last time? Can she suggest any reasons for past relapses? What things are happening in her life right now that could make it easy or difficult to quit?
  • Don’t assume expectant mothers know that tobacco is harmful to the fetus

    Some women are not necessarily well-informed about the health effects of smoking on the fetus. Ask her what she knows about the harmful health effects of tobacco and then what her concerns are, if any. Offer to provide her with information about the health effects of smoking for herself.
  • Remember that it’s never too late to quit smoking

    If a woman comes to your practice late in pregnancy, she may feel that damage has already been done to the fetus and that it’s too late to quit smoking. Remind the woman that quitting at any time has immediate health benefits for both herself and the fetus, regardless of previous smoking or future relapse.
  • Encourage harm reduction among pregnant smokers who are not ready to quit

    Discuss a range of options for changing smoking behaviours with women and assess readiness and opportunities for change. You can suggest decreasing the number of cigarettes smoked, brief periods of cessation at any point in pregnancy and around delivery, and encourage other health-promoting behaviours such as exercise and improved nutrition.
  • Nicotine replacement therapy is an option

    NRTs are not completely free of risk, but evidence suggests that NRTs are less harmful than smoking during pregnancy because both the woman and fetus receive less nicotine and no exposure to carbon monoxide and other toxic substances. For some groups of women, where other avenues to quit or reduce have not been successful, NRTs may be an option to discuss further.
  • Continue to encourage women who have quit smoking when they found out they were pregnant

    Nicotine is water- and lipid-soluble and so can be secreted in breast milk.

    The concentration of nicotine in breast milk will vary depending on how many cigarettes have been smoked since the last breastfeeding session and how much time has passed since the mother has last smoked a cigarette. Even so, Health Canada recommendations clearly indicate that smoking is not a contraindication to breastfeeding.
