How much cannabinoids are in breast milk?

Cannabinoids in Breast Milk: An Overview
Recent studies have shed light on the presence of cannabinoids in breast milk, revealing significant findings that raise questions about maternal cannabis use and its implications for breastfeeding infants.
Presence and Concentration of Cannabinoids
Research indicates that cannabinoids, particularly tetrahydrocannabinol (THC), are detectable in breast milk following maternal cannabis use. A study involving 54 samples from 50 breastfeeding mothers found that THC was present in 63% of the breast milk samples, with measurable levels persisting for up to six days after use. The concentrations of various cannabinoids in breast milk have been quantified, showing median levels of THC at 27.5 mcg/L, along with other cannabinoids such as 11-OH-THC, THC-COOH, and CBD.
Interestingly, the study also highlighted that the method of cannabis consumption—whether smoking or using edibles—did not significantly alter the cannabinoid levels in breast milk. This suggests that regardless of how cannabis is ingested, the compounds can transfer into breast milk, potentially affecting the nursing infant.
Implications for Infants
The presence of cannabinoids in breast milk raises concerns about the potential effects on infants. Cannabinoids are known to interact with the endocannabinoid system, which is crucial for various physiological processes, including appetite regulation and mood. Some anecdotal reports suggest that cannabinoids may help calm infants and stimulate their appetite. However, the long-term effects of cannabinoid exposure through breast milk remain largely unknown, prompting calls for further research into the implications of maternal cannabis use during breastfeeding.
Recommendations for Breastfeeding Mothers
Given the findings, health professionals often recommend that breastfeeding mothers abstain from cannabis use to avoid exposing their infants to cannabinoids. The potential for THC to remain in breast milk for extended periods—up to six weeks in some cases—highlights the need for caution. As the understanding of cannabinoids in breast milk evolves, it is crucial for mothers to consider the potential risks and consult healthcare providers regarding cannabis use during lactation.
In conclusion, while cannabinoids are indeed present in breast milk, the implications for infant health are still being explored. The evidence suggests a need for careful consideration and further investigation into how maternal cannabis use affects breastfeeding and infant development.

How much CBD is in breast milk?

Median (IQR) cannabidiol (CBD) concentrations were: plasma 0.6 ng/ml (0.5-6.4) and breast milk 1.2 ng/ml (0.5-17.0). Median (IQR) THC M/P: 7.0 (1.8-34.6) and CBD M/P: 2.6. Median breast milk THC concentration increased from visit 1 to visit 2 by 30.2 ng/ml (95% CI 3.05-69.3 ng/ml).

Does breastmilk have cannabinoids?

The cannabinoids THC and CBD are present and accumulate in breast milk after maternal cannabis use, whether by inhalation or edible ingestion. They appear rapidly after exposure and may remain present for at least 1–2 days.

Are cannabinoids present in breast milk?

So, it is not surprising that maternal endocannabinoids are incorporated into human milk. Twelve endocannabinoid-related compounds have been detected in human milk. The most abundant endocannabinoid in human milk is 2-AG. Levels of 2-AG do not seem to be impacted by handling and storage, but scientific data is limited.

Is it OK to have CBD while breastfeeding?

FDA strongly advises against the use of cannabidiol (CBD), tetrahydrocannabinol (THC), and marijuana in any form during pregnancy or while breastfeeding. Cannabis and Cannabis-derived products have become increasingly available in recent years, with new and different types of products appearing all the time.

How long do cannabinoids stay in breastmilk?

THC is stored in your fat cells, which means it sticks around for a long time. Studies show that although THC levels in breast milk peak one hour after use, it remains in your system for six days after use. That means you can’t just “pump and dump” milk after ingesting it to avoid exposing your baby to THC.

What drugs show up in breast milk?

Most drug molecules, including alcohol, nicotine and caffeine, are small enough to enter milk. Exceptions are drugs with high molecular weights such as heparins and insulin.

Can you breastfeed after taking CBD?

FDA strongly advises against the use of cannabidiol (CBD), tetrahydrocannabinol (THC), and marijuana in any form during pregnancy or while breastfeeding. Cannabis and Cannabis-derived products have become increasingly available in recent years, with new and different types of products appearing all the time.

Should I still breastfeed if I vape?

E-cigarettes, vaping and breastfeeding
New mums are advised to use licensed NRT products for help with quitting smoking and staying smokefree. However, if you do choose to use an e-cigarette to help you stay smokefree, it’s still better to carry on breastfeeding as the benefits will outweigh any potential harm.

Can smoke pass through breast milk?

Using tobacco or electronic cigarettes (e-cigarettes) while breastfeeding can allow harmful chemicals to pass from the mother to the infant through breast milk or secondhand smoke exposure. Mothers who use tobacco or e-cigarettes should be encouraged to quit.

How long do you wait to breastfeed after smoking?

Breastfeeding and cigarette smoke
Nicotine passes rapidly into your breast milk and affects how much milk you have. Nicotine in breast milk and passive smoking can give your baby chest infections, vomiting, diarrhoea and irritability. Avoid smoking for half an hour before you breastfeed.
