In pregnancy, nicotine replacement therapy has been shown to be:

• A. Effective
• B. Not effective
• C. Beneficial
• D. Harmful

Answer: (B)

The main idea here is whether nicotine replacement therapy actually helps pregnant people quit smoking. Evidence shows that while NRT is safer than continuing to smoke, it does not reliably increase quit rates in pregnancy compared with placebo or no pharmacotherapy. So, in terms of achieving smoking cessation during pregnancy, it isn’t considered effective as a standalone quit aid. It’s still used with counseling because it reduces exposure to the harmful substances in cigarette smoke, but that safety benefit doesn’t translate into strong efficacy for stopping smoking. The other options aren’t right: it isn’t clearly effective for quitting, it isn’t described as a clear beneficial aid for cessation in pregnancy, and it isn’t regarded as harmful in the way smoking is.
