Surprising Facts About Cannabis and Pregnancy

The topic of cannabis and pregnancy is perhaps one of the most controversial topics about the plant.

After all, many still believe that consuming a “mind-altering” substance makes you a terrible parent.

But, how bad is it to consume cannabis while pregnant?

Why are so many women picking up the cannabis habit?

As it turns out, women and cannabis are entangled in a long, complicated, and largely forgotten history.

Surprising Facts About Cannabis and Pregnancy


Here are 7 surprising facts about cannabis and pregnancy that you might not know:

1. Cannabis has been used as a women’s aid for millennia

From easing pain on wedding nights to calming teething children, the cannabis plant has been used as a women’s aid for millennia.

The herb was a popular choice among ladies in many ancient cultures for relief from menstrual and reproductive disorders.

Historical medical texts from ninth century Persia provide an example, where it is thought that juice from cannabis seeds was used to prevent miscarriages, maintain pregnancy, calm pains, and ease migraine.

2. Cannabis preparations were used to treat labor pain

Women have been using cannabis to help with labor pains for millennia.

Today, the most common medication for labor pain is an epidural.

Epidurals are injections that decrease sensation in the lower half of the body.

They are frequently administered with opioid pain medications and other narcotic drugs to ease the pains of labor.

Prior to the invention of modern medicine, however, our human ancestors had a different remedy: cannabis.

Cannabis was a major treatment for labor pains and the facilitation of childbirth for thousands of years.

Cannabis as a labor-aid was not unique to a single region.

Rather, many different societies in various parts of the world used the herb for this purpose.

These include Middle Eastern, Islamic, Egyptian, East Asian, Southeast Asian, and South African societies.

3. Cannabis was used in medicines to induce abortions

Historical evidence suggests that cannabis was used to facilitate labor and improve lactation in nursing mothers.

However, some societies also used the plant in concoctions intended to stimulate miscarriage or abortion.

Yet, experts suggest that cannabis might have been included in these elixirs thanks to its pain-relieving qualities.

4. Cannabis is still the most-used illicit substance during pregnancy

Several cultures around the world still use cannabis and hemp products during pregnancy.

Yet, the herb has been outlawed in many countries, particularly Western societies.

Regardless, according to the World Health Organization, cannabis is the illicit substance most-used by pregnant women worldwide.

While you’ll be hard-pressed to find medical professionals willing to suggest cannabis as a pregnancy remedy, many women still turn to the herb for relief from nausea and vomiting despite a lack of medical research on the topic.

5. Cannabis-like compounds are vital for reproduction

THC in cannabis mimics this molecule your body already produces naturally.

One of the reasons why cannabis use during pregnancy is so controversial today is because the human body naturally produces its own cannabis-like compounds.

These compounds are called endocannabinoids, named after cannabis.

Endocannabinoids, however, were not discovered until the early 1990s.

In the few short decades since, researchers have found that these molecules play vital roles in reproduction.

As it turns out, they are critical for the development of an infant’s brain.

This fact is one of the primary reasons medical professionals caution against cannabis use during pregnancy.

The timing and release of specific endocannabinoids at different stages of fetal development may have various effects on the developing baby.

How this might influence fetal development and development after birth is currently unknown.

Though, it is theorized that the herb may have a negative impact on memory, attention, and learn later in life.

Endocannabinoid compounds also play a role in fertility.

These cannabis-like molecules determine whether or not a fertilized egg implants in the uterus.

6. Studies on prenatal cannabis consumption are inconsistent

Cannabis today is significantly stronger than it was when our ancestors began cultivating the plant.

While it was once used frequently as a pregnancy and labor aid, medical professionals today have concerns about the healing herb.

Thus far, there is no conclusive evidence that cannabis causes negative birth outcomes.

However, some research has shown a correlation between prenatal cannabis use and undesirable effects. These include:

  • Low birthweight

  • Shorter duration of pregnancy

  • Poorer school outcomes

  • Cognitive changes

  • Longer time in the intensive care unit

Interestingly, researchers have had a difficult time pinning down firm correlations between cannabis and poor pregnancy outcomes.

This is perhaps largely due to the ethical issue of testing cannabis medicines on pregnant women, which could have lasting impacts on a child.

However, studying populations of cannabis-consuming mothers is also difficult.

Demographics like socioeconomic status and other factors like alcohol and tobacco consumption can contribute to unfavorable results, making it particularly difficult to tease out whether cannabis alone or a combination of factors created these outcomes.

Without knowing for sure, medical professionals will always recommend that mothers abstain from cannabis use during pregnancy.

7. Some studies have suggested potential benefits of prenatal cannabis exposure

While taking any substance while pregnant is risky, recent evidence suggests that there is much more to the cannabis and pregnancy question than meets the eye.

Surprisingly, a 2015 study published in Scientific Reports suggests that children exposed to cannabis in the womb have superior global motion perception at the age of four. Global motion perception is a test of cognitive development.

This particular test was designed to examine a region of the brain responsible for visual processing.

This particular region is thought to be sensitive to substances and scenarios that interfere with brain development.

Unfortunately, this test is merely one single study.

Like the research mentioned above, it also only suggests a correlation, not a causation.

Still, it is important.

Children with some types of cognitive and mental disabilities, such as autism, have poorer global motion perception.

In this instance, those exposed to cannabis were better off than those who were not.

This study was quite small, containing only 70 total participants who were exposed to various types of substances.
