The 101 on Maternal Marijuana Use

Many women, especially those using marijuana for medical conditions, ask us if it is safe to use before, during, and after pregnancy. Since extensive research is only beginning—and is hampered by federal laws in some cases—it’s hard to state findings conclusively, but iPuff Vape is committed to the safe and legal use of our products, so here is some information we think you should know.

Pre-Pregnancy Considerations

The psychoactive substance in marijuana, tetrahydrocannabinol (THC), is metabolized and stored in body fat like many other things we consume. Since the amount of time THC remains stored in fat can vary, it’s difficult to say how far in advance marijuana consumption should stop to be sure the THC clears the body before initiating a pregnancy. As to whether it’s necessary is another matter that is hotly debated, especially regarding its effects on developing fetuses and the trade-offs involved in its use during pregnancy.

Marijuana Use During Pregnancy

Is marijuana use safe during pregnancy? That depends on who you ask. Most medical and legal professionals choose to err on the side of caution and advise against it. But actual research is scarce and what little has been done often lacks important controls such as isolating coincidental alcohol, tobacco, and drug use.

When you ingest THC, it is present in the bloodstream, either directly or through metabolize fat. As such, it can pass through the placenta to the developing fetus. But the few well-controlled studies made seem to show its effect to be significantly less than that of alcohol or tobacco, and even those effects are far from conclusive. For a detailed look into the research, you can refer to this article on the NORML website.

At the same time, some pregnant women report that moderate marijuana use alleviates some of the negative side effects of pregnancy, most notably morning sickness and its life-threatening companion, Hyperemesis gravidarum (HG), a rare, but severe, form of morning sickness that causes weight loss and dehydration, typically from excessive vomiting. Some women also use marijuana in its various forms to address issues such as pain and anxiety, feeling that it’s a better alternative to prescription and OTC drugs.

The medical and legal establishment takes a firm stance in advocating against any form of marijuana use before, during, and after pregnancy. You can see the positon of Colorado’s Department of Public Health and Environment here.

Using Marijuana After Giving Birth

Even the most cautious opponents of using marijuana admit there’s no hard information on how long THC remains in breast milk or how it affects a nursing child. Here’s what the Colorado DPH&E has to say on its website, referenced above:

At this time, there is limited research on breastfeeding and marijuana use, including: the amount of THC in breast milk, the length of time THC remains in breast milk and effects on the infant. It is unknown how long after any use of marijuana that it is safe to breastfeed or how long THC remains in breast milk after occasional marijuana use as compared to regular use.

But to stay on the safe side, they also state:

Because of the potential risks to the baby, the American Academy of Pediatrics states that marijuana should not be used while breastfeeding.

Aside from nursing considerations, there are also other risks to using marijuana as a parent, risks that should be of concern to any responsible person. These include exposing children to marijuana smoke, weed, and edibles as well as being impaired while caring for the child or driving.

Which leads to the next topic.

Legal Concerns of Marijuana Use During and After Pregnancy

According to the Colorado DPH&E website, state law prevents prenatal substance abuse that is self-reported or detected during prenatal care from being used in criminal prosecution. On the other hand, a baby testing positive for a Schedule I substance, including THC, must be reported to Child Protective Services. Even if the use is justified (as in treating Hyperemesis gravidarum) this could result in unwanted consequences. It should be discussed with medical and legal counsel in advance to get ahead of any potential problems.

Of course, any irresponsible behavior that endangers a child also has legal consequences. So don’t do it!
