According to a study, vaping or snus during pregnancy increases the risk of SIDS by up to three times.
Both e-cigarettes and snus — also known as “dip tobacco” or smokeless tobacco — are growing in popularity among Americans looking to ditch traditional cigarettes and are sold in most convenience stores across the US.
They are seen by many as a safer alternative to traditional cigarettes, but there is growing evidence that they themselves pose health risks.
Researchers in Sweden examined the medical records of more than two million women and couples over the age of 20. They found that people who used snus – which was invented in Sweden – during pregnancy increased the risk of their baby dying before their first birthday by 70 percent.
Lead study author Dr. Anna Gunnerbeck, a pediatrician at Karolinska Institutet in Sweden, said all types of nicotine products should be avoided during pregnancy. “With the dramatic increase in snus use among young women of childbearing age in Sweden in recent years and the growing popularity of e-cigarettes, women need to be made aware of the potential risk to fetuses and babies.
A single cartridge of some vaporizers contains the same amount of nicotine as about 50 cigarettes

The graph above, from a separate study, shows that the prevalence of e-cigarettes has increased dramatically over the past three years among women aged 21-34 at peak fertility.
“Our research shows that nicotine is a risk factor for SIDS, so we conclude that all types of nicotine products should be avoided during pregnancy.”
She said that using snus can be as harmful to babies as smoking up to nine cigarettes a day.
All types of nicotine products should be avoided during pregnancy, the researchers conclude.
With snus, nicotine enters the system through the inside of the cheeks. When vaporized, it is inhaled through the lungs.
Nicotine is bad for baby’s development as it can damage the lungs and brain of unborn babies.
It is not clear how many pregnant women in the US vape or use snus.
But a single cartridge from some vaporizers contains the same amount of nicotine as about 50 cigarettes.
Sudden Infant Death Syndrome (SIDS), also known as SIDS, is the unexpected and unexplained death of an apparently healthy baby.
It is the leading cause of death in infants under the age of one in the United States, with approximately 3,400 infant deaths each year. In the UK there are around 200.
The dangers of smoking during pregnancy have long been recognized, including secondhand smoke increasing the risk of SIDS.
So few studies have been done on vaping, snus and other nicotine products in relation to SIDS.
Vapes do NOT help people stop smoking regular cigarettes

Researchers at George Washington University in Washington DC collected data from 545 people who regularly smoked and vaped. They found that after five years, more than half had discarded e-cigarettes, while only a third had quit smoking.
Snus, also called “dip” or smokeless tobacco, is a moist, powdered tobacco pouch that is usually held in the mouth between the lip and gum and releases nicotine into the bloodstream.
Unlike cigarettes, it contains no flammable ingredients, leading people to believe that snus, like vaping and other e-cigarettes, is not as bad for your health.
To fill the lack of research, doctors in Sweden examined records of more than two million babies born in the country between 1999 and 2019.
The study, published in the journal Pediatric Research, adjusted for risk factors for SID such as maternal socioeconomic status and age.
Only two out of 10,000 babies suffered from SID in the 20 years.
Just over one percent of mothers used snus and seven percent smoked when they reported for maternity care.
Snus use was associated with a 70 percent increase in the risk of infant death before the infant’s first birthday, from any cause, and a 3-fold increase in SID.
The risks associated with using snus were about the same as with smoking one to nine cigarettes a day.
However, smoking more than ten cigarettes a day is still the biggest risk for the babies.
And mothers could significantly reduce the risk of their baby dying if they stopped using snus before their first pregnancy date compared to continued use.
The researchers noted that they cannot say for sure that nicotine use caused the children’s deaths, as other unknown factors may have contributed.
They also did not know how much snus the expectant mothers consumed, whether mothers who quit smoking or using snus early in pregnancy returned to their habit later, or how much nicotine could harm the baby.
The study acknowledged that it is difficult to separate the risk to the fetus associated with snus and smoking from exposure to tobacco smoke and nicotine in breast milk after the baby is born.
