Although many studies in the past have shown the detrimental effects of nicotine and tobacco during pregnancy, the latest smoking babies ultrasound study shows some chilling changes in those women that don't stop smoking during their pregnancy, which affects their unborn children.

A new set of high-definition smoking babies ultrasound scans now suggests that the effects of nicotine and tobacco can be seen from the womb, as there's still about 10 percent of women in the United States that'll still continue to smoke even while they're expecting children.

According to Science Daily, the new smoking babies ultrasound study was recently published in the journal Acta Paediatrica under the title "Ultrasound observations of subtle movements: a pilot study comparing fetuses of smoking and non-smoking mothers," after long research in the Durham University in England, alongside coworkers in the University of Lancaster.

The Independent reports that the smoking babies ultrasound study shed even further light into the effects on the fetus when the mother smokes throughout the pregnancy, as the researchers used 4D ultrasound scans to detect the smallest moves of the unborn child inside the womb; through this method, the scientists were able to see step by step what the fetuses were doing in the womb, checking on whether they were developing properly.

The results found in the smoking babies ultrasound study were, by all accounts, astounding; The Huffington Post reports that, through the high-definition 4D ultrasound scans, the researchers responsible for the study found that the fetus' movements were greatly affected when their mothers smoked.

In fact, the results showed that the fetuses weren't moving their mouths and hands the same way as those whose mothers didn't smoke, marking a less natural development; the researchers of the study have stated that it is most likely that the smoking babies ultrasound show that their nervous systems weren't developing in the right way.

The smoking babies ultrasound study aims to create conscience among mothers to stop the habit during gestation.
