How does marijuana affect breast milk production?

The Impact of Marijuana on Breast Milk Production
As the conversation around marijuana use continues to evolve, many new mothers are left wondering about its effects on breastfeeding. The intersection of cannabis consumption and lactation raises critical questions about safety and health implications for both mothers and infants.
Hormonal Effects on Milk Production
Research indicates that marijuana can negatively influence the hormones essential for breast milk production. Specifically, cannabinoids, including tetrahydrocannabinol (THC), can affect levels of oxytocin and prolactin, hormones that play pivotal roles in lactation. Prolactin is crucial for milk synthesis, while oxytocin is responsible for milk ejection during breastfeeding. Disruption of these hormones could potentially lead to reduced milk supply, contrary to the common misconception that cannabis might enhance lactation like some herbal remedies, such as fenugreek.
THC Transfer to Breast Milk
One of the most concerning aspects of marijuana use during breastfeeding is the transfer of THC into breast milk. Studies have shown that THC can be excreted in small quantities into breast milk, with detection times varying significantly. The Food and Drug Administration (FDA) has reported that THC can remain in breast milk for up to six days, and in some cases, it may be detectable for even longer periods. This prolonged presence raises concerns about the potential exposure of infants to THC, which could have developmental implications.
Potential Developmental Risks
While some studies suggest that infants exposed to THC through breast milk may not show immediate adverse effects, there are indications of longer-term developmental risks. For instance, research has linked THC exposure to poorer motor development scores in infants at one year of age. This highlights the importance of caution for breastfeeding mothers who consume marijuana, as the long-term effects on infant development are still not fully understood.
Recommendations for Breastfeeding Mothers
Given the potential risks associated with marijuana use during breastfeeding, health professionals generally advise lactating mothers to refrain from consuming cannabis. The consensus is that the safety of both the mother and the infant should take precedence, and discontinuing marijuana use is recommended to avoid any possible negative impacts on milk production and infant health.
In conclusion, while the allure of marijuana for managing conditions like chronic pain may be tempting for new mothers, the implications for breast milk production and infant health are significant. The hormonal disruptions and potential developmental risks associated with THC exposure underscore the need for careful consideration and consultation with healthcare providers. As research continues to evolve, it remains crucial for mothers to stay informed and prioritize the well-being of their children.

Can smoking stop your breast from producing milk?

Smoking can cause low milk supply, colic, and milk let-down issues. If you do continue to smoke, you should still breastfeed. Your milk can protect your baby from breathing problems, sudden infant death (SIDS), and poor weight gain. Wait as much time as possible between smoking and breastfeeding.

How long should 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.

What drugs pass through 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.

How long does it take for marijuana to metabolize in breast milk?

The study found that, while the concentrations of THC varied from woman to woman (likely depending on their level of use, BMI and metabolism), THC was excreted in the breast milk of these seven women for up to six weeks.

What can you not do while breastfeeding?

What foods and drinks should I limit or avoid while breastfeeding?

• Alcohol. There’s no level of alcohol in breast milk that’s considered safe for a baby.
• Caffeine. Avoid drinking more than 2 to 3 cups (16 to 24 ounces) of caffeinated drinks a day.
• Fish. Seafood can be a great source of protein and omega-3 fatty acids.

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.

Does marijuana affect breast milk supply?

Cannabis can affect hormones involved in breastmilk production, including oxytocin and prolactin. Lower levels of these hormones can lower milk supply. Keeping up a plentiful milk supply is important for continuing to breastfeed.

How long after taking drugs can I breastfeed?

A breastfeeding plan
If you do use drugs such as amphetamines or heroin as a one-off, you will need to express your breast milk in the 24 hours afterwards and throw it away before you breastfeed again.

How much cannabinoids are in breast milk?

Mean baseline milk Δ9-THC concentration after the 12-hour cannabis abstention was 36.5 (48.0) ng/mL (Table 1, Fig. 2). Mean concentration after initial cannabis use (post-cannabis use) was 104.4 (126.3) ng/mL. Participants’ average Δ9-THC concentration in milk after cannabis use ranged from 2.9 to 312.6 ng/mL (Fig.

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.
