As a precaution, avoid CBD during pregnancy and breastfeeding. No health agency can currently guarantee a safe dose, and available animal studies show alterations in neurological development in exposed offspring. If you have used it recently, speak to your doctor or midwife immediately: it's not a mistake, it's useful information for your follow-up care.
In short:
- CBD consumption during pregnancy or breastfeeding is strongly discouraged due to the lack of scientific evidence and potential risks already observed in animals.
- Because CBD is lipophilic, it can accumulate in fatty tissues and cross the placenta, exposing the fetus to prolonged release.
- No safe dose of CBD is currently established for pregnancy, and human studies remain insufficient to provide certainty.
- Commercially available CBD products may contain traces of THC or contaminants, which further increases the risks to the developing baby.
- In case of recent consumption, it is essential to quickly inform a healthcare professional to adjust obstetric monitoring.

Why is CBD a cause for concern during pregnancy?
Cannabidiol (CBD) is not a harmless molecule simply because it is sold in pharmacies or specialty stores. Its chemical structure makes it lipophilic, meaning it readily binds to fatty tissues, including breast tissue. Therefore, CBD is not eliminated instantly: it can accumulate and be released gradually, prolonging exposure well after the last use.
This characteristic is a game-changer during pregnancy. The placenta is not an impermeable barrier to all substances, and many lipophilic compounds cross it easily. A single exposure in the mother can therefore translate into prolonged exposure for the fetus, whose organs and brain are developing at a rate where every week counts.
There is also an often overlooked aspect: CBD can interact with certain liver enzymes, particularly those of the CYP450 family, which are involved in the metabolism of many medications. In a pregnant woman undergoing treatment for hypertension, gestational diabetes, or any other condition, this interaction can alter the effectiveness or toxicity of other prescribed substances.
What many expectant mothers forget:
- The term "natural" is meaningless in pharmacology. Hemlock is also natural.
- An over-the-counter CBD product has not been subject to the same controls as a medicine.
- Accumulation in body fat can prolong exposure in breastfed infants, even after maternal consumption has ceased.
- Drug interactions often go unnoticed by consumers who think CBD is "just a plant".
Pro tip: If you are taking regular medication, never assume that CBD is compatible "because it's natural." Always ask your doctor to check for potential interactions before taking it, whether you are pregnant or not.
State of the evidence: animal studies, human data, and ongoing trials
Data on CBD and pregnancy remain fragmented, and it is precisely this lack of information that justifies caution. Animal studies, however, are not without their concerning signs. Research conducted on mouse models shows alterations in neurological development and behavior in offspring exposed to CBD in utero, with effects that persist after birth.
These results do not automatically translate to humans, but they are enough to raise concerns among researchers. Furthermore, ANSES (the French Agency for Food, Environmental and Occupational Health & Safety) has proposed classifying CBD as a substance presumed toxic to human reproduction, a regulatory category that reflects a genuine level of concern based on the effects observed on fertility and neurodevelopment in animal models.
From a human perspective, the picture is almost empty. We mainly have observational studies, often limited by small sample sizes or the difficulty of isolating the effect of CBD alone when participants also consume THC or other substances. This lack of robust data is not proof of safety; it simply means we don't know.
To fill this gap, a dedicated clinical trial was launched. The NCT06589258 study specifically examines the passage of CBD into breast milk and its potential biological impact on breastfed infants. Recruitment began in 2025, but final results are not expected for several years.
Some key points to remember about the current state of knowledge:
- Animal studies show neurodevelopmental effects, but in mice, not in humans.
- Existing human data is mostly observational and insufficient to establish a safety threshold.
- The NCT06589258 trial is an ongoing clinical study aimed at measuring the passage of CBD into breast milk and its potential effects, but its results are not yet available.
- reviews point to major gaps in longitudinal data on long-term neurodevelopment.
What science actually says today: no controlled human study has ever established a safe dose of CBD during pregnancy. It's not a lack of statistics, it's the absolute certainty.
This level of evidence does not allow for a firm positive or negative conclusion regarding humans. It is precisely this lack of evidence, combined with warning signs from animals, that leads health agencies to recommend abstinence rather than wait for confirmation that will take years.
What do health authorities say about CBD during pregnancy?
Major health agencies are converging on a simple message, even if they don't always refer to CBD alone. The FDA has explicitly warned pregnant and breastfeeding women to avoid all cannabis products, including CBD, due to a lack of sufficient safety data.
In Canada, the position is just as clear. Health Canada recommends avoidingall cannabis consumption, including products containing CBD, during conception, pregnancy and breastfeeding, emphasizing that no quantity has been identified as safe.
In France, the MILDECA (Interministerial Mission for the Fight against Drugs and Addictive Behaviors) and publications relayed on drogues.gouv.fr (the French drug website) adopt the same approach, supported by ANSES (French Agency for Food, Environmental and Occupational Health & Safety) work on potential reproductive toxicity. These positions are based on three recurring arguments:
- The absence of a scientifically established safe dose makes any recommendation of a "small tolerated amount" impossible.
- The risk of contamination of products sold in a market that is still largely unregulated.
- The potential effects on fetal and neonatal development, documented in animals and suspected in humans.
The practical advice that comes up in all these publications remains the same: talk to a healthcare professional before making any decisions, and never self-medicate with a CBD product to manage a pregnancy symptom, even a minor one.
Risks related to CBD product quality and contamination
Even setting aside the issue of CBD itself, the market presents a separate problem: what's actually in the bottle. Tests conducted on products marketed as "pure CBD" regularly reveal undeclared traces of THC, sometimes enough to produce psychoactive effects or cross the placental barrier at concerning levels.
This isn't the only risk. Hemp is a bioaccumulator, meaning it readily absorbs heavy metals and pesticides present in its growing environment. A poorly controlled product can therefore concentrate toxins that have absolutely no place in the body of a pregnant woman.
The consequences for pregnancy and the infant far exceed those of CBD alone:
- Involuntary exposure to THC, with documented neurodevelopmental effects that are more severe than those of CBD.
- Accumulation of heavy metals (lead, cadmium, mercury) that can affect fetal development.
- Pesticide residues transmitted through the placenta or breast milk.
- Labeling is often misleading regarding the actual concentration of cannabinoids.
Pro tip: If, despite recommendations, you're considering a CBD product after giving birth and while not breastfeeding, always demand a third-party laboratory certificate of analysis (COA) that clearly states the levels of THC, heavy metals, and pesticides. A reputable seller will provide this without question. Our article on contaminants in low-quality CBD products details how to read these documents.
Traceability of organic hemp and independent third-party testing remain the only reliable indicators of seriousness in this market, well after pregnancy and breastfeeding.
How to relieve nausea, anxiety and sleep disorders without CBD?
The symptoms that CBD claims to relieve—nausea, anxiety, insomnia—have validated solutions that don't present the same uncertainties. Here's a concrete step-by-step guide, to be adjusted with your healthcare professional according to your situation.
- For nausea : favor small, frequent meals rather than three large meals, avoid prolonged fasting, and talk to your midwife about ginger in medical form, the supervised use of which is better documented than CBD for this specific indication.
- For anxiety : Cognitive behavioral therapy (CBT) adapted for pregnancy has proven effective in treating perinatal anxiety, without risk to the fetus. Guided breathing techniques and progressive muscle relaxation can also be practiced independently on a daily basis.
- For sleep : good sleep hygiene remains essential, namely regular sleep schedules, a cool and dark bedroom, and turning off screens an hour before bedtime. Perinatal physiotherapy and, in some cases, acupuncture performed by a trained professional knowledgeable about pregnancy can complement these measures.
- For any medication-based solution : never make a decision alone. Some treatments for severe nausea or debilitating anxiety are compatible with pregnancy, but their selection depends on your medical history and requires a prescription.
These alternatives have one thing in common: they rely on professional support rather than self-medication, which completely changes the logic of managing pregnancy symptoms.
What should you do if you have already taken CBD recently?
Don't panic, but don't be inactive either. The first step is to inform your doctor or midwife as soon as possible, describing as precisely as possible the product consumed, the approximate quantity, and the time of ingestion. This information allows them to assess whether monitoring is necessary and to answer your questions without judgment.
Depending on your situation, your healthcare professional may decide to adjust the obstetric monitoring, for example by monitoring certain parameters during the next ultrasounds or consultations, although this remains rare for occasional and long-standing consumption.
If you are breastfeeding or planning to do so, the discussion should also address the time elapsed since the last dose, given the possible accumulation of CBD in fatty tissues and its gradual release into breast milk.
Some useful points to consider for this exchange:
- Note the date, quantity and type of product (oil, flower, capsule) to provide accurate information.
- Don't omit anything for fear of judgment: transparency only serves your monitoring and that of your child.
- Explicitly ask if a waiting period is recommended before confidently resuming breastfeeding.
- Consider this decision as a shared one between you and your caregiver, not a choice to be made alone in uncertainty.
What this question reveals about our relationship with CBD
The precautionary principle is not a timid stance; it is the only tenable logic in the face of such a vast lack of data. Animal studies point to real risks to neurological development, a clinical trial is underway to understand the passage of CBD into breast milk, and no reputable health agency has identified a safe threshold. Combining these three facts provides a clear answer, even without absolute certainty about the exact mechanism.
The quality and traceability of the products do not change this recommendation: CBD consumption remains contraindicated during pregnancy and breastfeeding, as the problem lies with the molecule itself. Our role is to provide you with the most honest information possible, even when it costs us a sale, and to remain available to answer your questions before, during, and after pregnancy.

Frequently Asked Questions
Is CBD completely prohibited during pregnancy?
There is no legal ban on CBD for pregnant women in France, but all health authorities recommend avoiding its consumption as a precaution, due to the lack of a dose recognized as safe.
Does CBD pass into breast milk?
This is likely given the lipophilic nature of the molecule, but precise data are still lacking. The NCT06589258 clinical trial is currently rigorously investigating this transition.
Can CBD cause miscarriage or birth defects?
No human study confirms such a direct link, but animal studies showing effects on neurological development and the proposal by ANSES to classify CBD as presumed toxic to reproduction justify strict caution.
Can I use CBD cream during pregnancy?
Data on the skin absorption of CBD during pregnancy remains insufficient to consider it risk-free. The precautionary principle recommended by health agencies also applies to topical products.
Where can I find quality-controlled CBD products at Lord Of CBD?
Lord Of Cbd offers flowers, resins and oils from organic hemp with a THC level that complies with the law and verifiable traceability on each product, which can be consulted directly on Lordofcbd once the pregnancy and breastfeeding period is over.
