Quick verdict: ❌ Best avoided. Marijuana smoke—whether from joints, pipes, or bongs—is not considered safe at any point during pregnancy. The American College of Obstetricians and Gynecologists (ACOG), the Centers for Disease Control and Prevention (CDC), and the NHS all recommend avoiding marijuana in any form, including smoke, due to potential risks to your baby’s brain development, birth weight, and long-term health. If you’ve already smoked, don’t panic—focus on stopping now and talking to your provider about safer ways to manage symptoms.
You’re sitting on the couch at 11 p.m., staring at the half-smoked joint in your hand. The nausea from your first trimester hasn’t let up all day, and you’ve heard that weed can help with morning sickness. But now you’re Googling “is marijuana smoke safe during pregnancy”, and the conflicting results are making your head spin. Or maybe you didn’t realize you were pregnant until after that last weekend with friends—and now you’re terrified about what the smoke might have done to your baby.
Take a deep breath. We’re going to walk through what the science actually says about marijuana smoke and pregnancy, trimester by trimester, how much (if any) is considered safe, and what to do if you’ve already used it. Most importantly, we’ll give you a list of safer alternatives that can help with nausea, anxiety, or pain without the risks. You’re not alone in this worry—many moms have been in your exact spot. Let’s get you clear, evidence-based answers so you can make the best choice for you and your baby.
| Trimester | Verdict | Notes |
|---|---|---|
| First trimester (weeks 1–12) | ❌ Avoid | Critical period for brain and organ development. THC crosses the placenta and may disrupt neural pathways. No safe amount is established. |
| Second trimester (weeks 13–26) | ❌ Avoid | Baby’s brain continues developing rapidly. THC exposure is linked to lower birth weight and potential learning difficulties later in life. |
| Third trimester (weeks 27–40) | ❌ Avoid | THC can affect fetal growth and may increase the risk of preterm birth. It also passes into breast milk, so avoidance is recommended if breastfeeding. |
| Breastfeeding | ❌ Avoid | THC concentrates in breast milk and can affect your baby’s brain development. The AAP recommends abstaining from marijuana while nursing. |
What is marijuana smoke?
Marijuana smoke comes from burning the dried flowers, leaves, stems, or seeds of the Cannabis sativa or Cannabis indica plant. When you inhale the smoke—whether from a joint, pipe, bong, or blunt—you’re breathing in hundreds of chemicals, including tetrahydrocannabinol (THC), the compound responsible for marijuana’s psychoactive effects, and cannabidiol (CBD), which doesn’t cause a “high” but may have other effects. Marijuana smoke also contains many of the same harmful chemicals found in tobacco smoke, such as tar, ammonia, and carbon monoxide, which can irritate your lungs and affect oxygen levels in your blood.
Unlike edibles or tinctures, smoking marijuana delivers THC to your bloodstream almost instantly, with effects peaking within 30 minutes and lasting up to 3 hours. This rapid onset can make it harder to control dosage, which is especially concerning during pregnancy when even small amounts of THC may pose risks to your baby. Marijuana smoke is also often shared in social settings, increasing your exposure to secondhand smoke, which carries its own set of concerns for pregnant women.
Is marijuana smoke safe during pregnancy?
Here’s what we know: THC binds to cannabinoid receptors in the brain, which play a key role in fetal brain development. Studies in animals and humans suggest that prenatal exposure to THC may be linked to lower birth weight, preterm birth, and long-term issues with memory, attention, and behavior. For example, a 2018 study published in JAMA Psychiatry found that children exposed to marijuana in the womb were more likely to have problems with impulse control and hyperactivity at age 10. While research is still evolving, the potential risks have led major health organizations to recommend avoiding marijuana entirely during pregnancy.
It’s also worth noting that marijuana smoke contains many of the same harmful chemicals as tobacco smoke, including carbon monoxide, which reduces the amount of oxygen your baby receives. Unlike tobacco, however, marijuana is not regulated for safety during pregnancy, so there’s no way to know the exact potency or purity of what you’re smoking. This lack of regulation makes it even harder to determine a “safe” amount.
If you’re using marijuana to manage symptoms like nausea, anxiety, or pain, it’s important to know that there are safer alternatives backed by obstetricians. We’ll cover those in detail later in this article. For now, if you’re feeling overwhelmed or unsure about how to quit, your provider can help you create a plan that works for you—without judgment.
Is marijuana smoke safe in the first trimester of pregnancy?
The first trimester (weeks 1–12) is the most critical period for your baby’s development. During these early weeks, the neural tube forms (which will become the brain and spinal cord), the heart begins to beat, and major organs start taking shape. This is also when your baby is most vulnerable to teratogens—substances that can cause birth defects or developmental issues. Unfortunately, marijuana smoke is not safe in the first trimester, and experts strongly recommend avoiding it entirely.
THC crosses the placenta and can interfere with the endocannabinoid system, a network of receptors that helps regulate brain development. Animal studies have shown that THC exposure during early pregnancy can disrupt the formation of neural pathways, potentially leading to long-term cognitive and behavioral issues. While human studies are limited due to ethical concerns, observational research has linked first-trimester marijuana use to an increased risk of miscarriage, low birth weight, and developmental delays. For example, a 2020 study in Nature Medicine found that babies exposed to THC in the first trimester were more likely to be born preterm and have lower Apgar scores (a measure of a newborn’s health).
If you used marijuana before you knew you were pregnant, try not to panic. Many women have been in your shoes, and the most important thing you can do now is stop. Focus on the steps you can take today—like talking to your provider about safer symptom management—and remember that your baby’s development is a marathon, not a sprint. The first trimester is critical, but it’s not the only factor in a healthy pregnancy.
Is marijuana smoke safe in the second trimester of pregnancy?
The second trimester (weeks 13–26) is often called the “honeymoon phase” of pregnancy—morning sickness fades for many women, energy levels rise, and you might even start feeling those first flutters of movement. But while your baby is growing rapidly during this time, their brain is still developing at a remarkable pace. Marijuana smoke is not safe in the second trimester, and continuing to use it may pose risks to your baby’s cognitive and behavioral development.
During the second trimester, your baby’s brain begins forming complex structures, including the cerebral cortex (responsible for thinking, memory, and language) and the hippocampus (involved in learning and emotion). THC can disrupt this process by interfering with the endocannabinoid system, which plays a key role in neural development. A 2019 study in JAMA Pediatrics found that children exposed to marijuana in the second trimester were more likely to show signs of anxiety, depression, and attention problems by age 6. Other research has linked second-trimester marijuana use to lower birth weight and an increased risk of preterm birth.
It’s also worth noting that smoking marijuana—like smoking tobacco—can reduce the amount of oxygen in your blood, which may affect your baby’s growth. Carbon monoxide, a harmful chemical in marijuana smoke, binds to hemoglobin more easily than oxygen, meaning your baby gets less of the oxygen they need to thrive. If you’re struggling with symptoms like nausea, anxiety, or insomnia, talk to your provider about safer alternatives. There are evidence-based options that can help without the risks.
Is marijuana smoke safe in the third trimester of pregnancy?
The third trimester (weeks 27–40) is a time of rapid growth and preparation for birth. Your baby is putting on weight, their lungs are maturing, and their brain is making the final connections that will support them after delivery. Marijuana smoke is not safe in the third trimester, and continuing to use it may increase the risk of complications like preterm birth, low birth weight, and developmental delays.
THC continues to cross the placenta in the third trimester, and your baby’s brain remains vulnerable to its effects. A 2021 study in Pediatrics found that babies exposed to marijuana in the third trimester were more likely to have lower birth weights and require neonatal intensive care (NICU) admission. The study also noted that THC can affect the production of myelin, a fatty substance that insulates nerve fibers and helps signals travel efficiently in the brain. Disruptions in myelination may contribute to long-term cognitive and behavioral issues.
Additionally, smoking marijuana in the third trimester can increase your risk of preterm labor. THC may stimulate contractions by interacting with receptors in the uterus, and the carbon monoxide in smoke can further stress your baby by reducing oxygen supply. If you’re using marijuana to manage pain, anxiety, or sleep issues, talk to your provider about safer options. There are non-pharmacological and medication-based alternatives that can help you feel more comfortable as you approach your due date.
If you’re breastfeeding or planning to breastfeed, it’s important to know that THC concentrates in breast milk and can be passed to your baby. The American Academy of Pediatrics (AAP) recommends avoiding marijuana while nursing due to potential risks to your baby’s brain development. If you’re struggling to quit, your provider can connect you with resources and support.
How much marijuana smoke, if any, is considered safe during pregnancy?
There is no known safe amount of marijuana smoke during pregnancy. Unlike alcohol, where some studies suggest very light use may not pose significant risks, marijuana—especially when smoked—has not been studied enough to establish a “safe” threshold. The American College of Obstetricians and Gynecologists (ACOG) and the CDC both state that no amount of marijuana use is considered safe during pregnancy due to the potential risks to your baby’s brain and body.
Here’s why: THC, the psychoactive compound in marijuana, crosses the placenta and can affect your baby’s developing brain at any stage of pregnancy. Even small amounts of THC may disrupt the endocannabinoid system, which plays a crucial role in neural development. A 2017 study in Obstetrics & Gynecology found that even low-level marijuana use during pregnancy was associated with lower birth weight and an increased risk of preterm birth. The study also noted that the effects of THC may be dose-dependent, meaning higher exposure could lead to greater risks.
It’s also important to consider that marijuana smoke contains many of the same harmful chemicals as tobacco smoke, including tar, ammonia, and carbon monoxide. These chemicals can reduce the amount of oxygen your baby receives, which may affect their growth and development. Because marijuana is not regulated for safety during pregnancy, there’s no way to know the exact potency or purity of what you’re smoking, making it impossible to determine a “safe” dosage.
If you’re using marijuana to manage symptoms like nausea, anxiety, or pain, talk to your provider about safer alternatives. There are evidence-based options—like vitamin B6 for nausea, prenatal yoga for anxiety, or acetaminophen for pain—that can help without the risks. If you’re struggling to quit, your provider can also connect you with resources like counseling or support groups to help you stop safely.
What are the health risks of smoking marijuana while pregnant?
Smoking marijuana during pregnancy may pose both short-term and long-term risks to you and your baby. While research is still evolving, the current evidence suggests that THC exposure can affect fetal development, birth outcomes, and even your child’s health later in life. Here’s what we know about the potential risks:
Risks to your baby
- Low birth weight: Babies exposed to marijuana in the womb are more likely to be born weighing less than 5.5 pounds, which can increase their risk of health problems like infections, breathing difficulties, and developmental delays. A 2019 meta-analysis in JAMA found that marijuana use during pregnancy was associated with a 77% higher risk of low birth weight.
- Preterm birth: Marijuana use may increase your risk of going into labor before 37 weeks, which can lead to complications like breathing problems, feeding difficulties, and long-term developmental issues. A 2020 study in JAMA Network Open found that women who used marijuana during pregnancy were 41% more likely to deliver preterm.
- Developmental delays: THC can disrupt the formation of neural pathways in your baby’s brain, potentially leading to issues with memory, attention, and learning. A 2018 study in JAMA Psychiatry found that children exposed to marijuana in the womb were more likely to show signs of hyperactivity, impulsivity, and lower cognitive function by age 10.
- Stillbirth: While the evidence is limited, some studies suggest that marijuana use during pregnancy may be linked to a higher risk of stillbirth. A 2019 study in Obstetrics & Gynecology found that women who used marijuana were more likely to experience stillbirth, though the study noted that other factors (like tobacco use) may also play a role.
Risks to you
- Reduced oxygen supply: Marijuana smoke contains carbon monoxide, which binds to hemoglobin in your blood more easily than oxygen. This means your baby may receive less oxygen, which can affect their growth and development.
- Increased heart rate: THC can cause your heart rate to rise, which may be uncomfortable or even dangerous if you have an underlying heart condition.
- Lung irritation: Smoking marijuana can irritate your lungs and airways, leading to coughing, wheezing, and an increased risk of respiratory infections. This can be especially problematic during pregnancy, when your immune system is already working overtime.
- Mental health effects: While some women use marijuana to manage anxiety or depression, THC can actually worsen these symptoms in some people. It may also increase your risk of developing psychosis or other mental health conditions, especially if you have a family history of these issues.
Long-term risks to your child
Some of the most concerning risks of prenatal marijuana exposure may not become apparent until your child is older. Research suggests that children exposed to THC in the womb may be more likely to experience:
- Learning difficulties and lower IQ scores
- Behavioral problems, such as ADHD or aggression
- Anxiety, depression, or other mental health issues
- Substance use disorders later in life
It’s important to note that many of these studies are observational, meaning they can’t prove that marijuana caused these outcomes—only that there’s an association. However, the consistency of the findings across multiple studies has led major health organizations to recommend avoiding marijuana during pregnancy.
If you’re using marijuana to manage symptoms like nausea, anxiety, or pain, talk to your provider about safer alternatives. There are evidence-based options that can help without the risks. And if you’re struggling to quit, remember that it’s never too late to stop. Your provider can help you create a plan that works for you and your baby.
Are there any marijuana brands that are safer for pregnant women?
No marijuana brand or product is considered safe for use during pregnancy. Unlike prescription medications, which undergo rigorous testing for safety and efficacy, marijuana products are not regulated by the FDA for use during pregnancy. This means there’s no way to guarantee the potency, purity, or safety of any marijuana brand—whether it’s a high-THC strain, a CBD-dominant product, or a “natural” or “organic” option. The American College of Obstetricians and Gynecologists (ACOG) and the CDC both advise against using any form of marijuana, including edibles, tinctures, or topicals, while pregnant or breastfeeding.
Some women wonder if CBD products—especially those labeled “THC-free”—might be a safer alternative. While CBD doesn’t cause the psychoactive “high” associated with THC, it’s not risk-free during pregnancy. The FDA has not approved any CBD products for use during pregnancy, and research on its safety is still limited. A 2020 study in Reproductive Toxicology found that CBD may interfere with fetal brain development, though more research is needed. Additionally, many CBD products on the market are mislabeled, meaning they may contain higher levels of THC than advertised or other contaminants like pesticides or heavy metals.
If you’re considering using marijuana to manage symptoms like nausea, anxiety, or pain, it’s important to know that there are safer, evidence-based alternatives available. For example:
- Nausea: Vitamin B6, ginger supplements, or prescription medications like doxylamine (Unisom) are often recommended by obstetricians.
- Anxiety: Prenatal yoga, meditation, or therapy (such as cognitive behavioral therapy) can help manage stress and anxiety without medication.
- Pain: Acetaminophen (Tylenol) is generally considered safe for short-term use during pregnancy, though you should always check with your provider first.
If you’re struggling to quit marijuana, your provider can connect you with resources like counseling, support groups, or behavioral therapy to help you stop safely. Remember, there’s no “safe” marijuana brand or product during pregnancy, but there are plenty of safer ways to manage your symptoms.
Can CBD oil be a safer alternative to smoking marijuana during pregnancy?
No, CBD oil is not considered a safe alternative to smoking marijuana during pregnancy. While CBD (cannabidiol) doesn’t produce the psychoactive “high” associated with THC, it’s not risk-free for pregnant women. The FDA has not approved any CBD products for use during pregnancy, and research on its safety is still in the early stages. A 2020 study in Reproductive Toxicology found that CBD may interfere with fetal brain development, though more research is needed to understand the full extent of these risks.
One of the biggest concerns with CBD oil is that it’s not regulated by the FDA, meaning there’s no way to guarantee its purity or potency. Many CBD products on the market are mislabeled, containing higher levels of THC than advertised or other contaminants like pesticides, heavy metals, or solvents. A 2017 study in JAMA found that nearly 70% of CBD products sold online were mislabeled, with some containing no CBD at all and others containing significant amounts of THC. This lack of regulation makes it impossible to determine a safe dosage or ensure that the product is free from harmful substances.
Additionally, CBD can interact with other medications you may be taking during pregnancy, such as antidepressants, blood thinners, or anti-seizure drugs. These interactions can affect how your body processes the medication, potentially leading to harmful side effects. If you’re considering CBD oil for symptoms like nausea, anxiety, or pain, it’s important to talk to your provider first. They can help you weigh the risks and benefits and recommend safer alternatives that are backed by evidence.
For example:
- Nausea: Vitamin B6, ginger supplements, or prescription medications like doxylamine (Unisom) are often recommended by obstetricians.
- Anxiety: Prenatal yoga, meditation, or therapy (such as cognitive behavioral therapy) can help manage stress and anxiety without medication.
- Pain: Acetaminophen (Tylenol) is generally considered safe for short-term use during pregnancy, though you should always check with your provider first.
If you’re struggling with symptoms and considering CBD oil, remember that there are safer, more reliable options available. Your provider can help you find the best approach for you and your baby.
Is secondhand marijuana smoke harmful to a pregnant woman and her baby?
Yes, secondhand marijuana smoke can be harmful to you and your baby during pregnancy. While research on secondhand marijuana smoke is still limited compared to tobacco smoke, the available evidence suggests that it may pose risks similar to those of direct exposure. Secondhand marijuana smoke contains many of the same harmful chemicals as tobacco smoke, including THC, carbon monoxide, tar, and ammonia. These chemicals can reduce the amount of oxygen in your blood, which may affect your baby’s growth and development.
A 2016 study in Pediatric Research found that THC can be detected in the blood and urine of non-smokers exposed to secondhand marijuana smoke, though at much lower levels than in active smokers. However, even low levels of THC may pose risks to your baby’s developing brain. The study also noted that secondhand smoke can irritate your lungs and airways, leading to coughing, wheezing, and an increased risk of respiratory infections—all of which can be especially problematic during pregnancy.
Additionally, secondhand marijuana smoke may contain higher levels of carbon monoxide than tobacco smoke, which can further reduce the amount of oxygen your baby receives. Carbon monoxide binds to hemoglobin in your blood more easily than oxygen, meaning your baby gets less of the oxygen they need to thrive. This can affect fetal growth and increase the risk of complications like low birth weight or preterm birth.
If you’re around people who smoke marijuana, it’s important to take steps to protect yourself and your baby. Here are some tips:
- Avoid enclosed spaces: Secondhand smoke is most harmful in small, poorly ventilated areas like cars, apartments, or bars. If you can’t avoid these spaces, ask the smoker to step outside or move to a well-ventilated area.
- Ask for smoke-free environments: Many workplaces, restaurants, and public spaces have smoke-free policies. If you’re in a situation where marijuana is being smoked, don’t hesitate to speak up and ask for a smoke-free area.
- Talk to your provider: If you’re concerned about your exposure to secondhand smoke, your provider can help you assess your risks and recommend steps to minimize them. They can also monitor your baby’s growth and development more closely if needed.
If you’re struggling with symptoms like nausea, anxiety, or pain and are considering marijuana as a solution, remember that there are safer alternatives available. Your provider can help you find the best approach for you and your baby.
Side effects and risks
