What percentage of THC is in breastmilk?

Understanding THC Levels in Breastmilk
Recent research has shed light on the presence of tetrahydrocannabinol (THC), the psychoactive component of marijuana, in breastmilk. This topic has garnered attention due to the increasing use of cannabis among new mothers and the potential implications for breastfeeding infants.
THC Concentration in Breastmilk
Studies indicate that THC can be detected in breastmilk, but the concentrations are relatively low. One significant finding from a study conducted by Children’s Colorado experts revealed that the median concentration of THC in breastmilk was approximately 27.5 micrograms per liter (mcg/L), with a range from 0.8 to 190.5 mcg/L. This suggests that while THC does transfer into breastmilk, the amounts are not substantial.
Infant Exposure to THC
When considering how much THC an infant might ingest through breastfeeding, estimates suggest that exclusively breastfed infants could receive about 2.5% of the maternal dose of THC. This translates to an average daily intake of around 0.07 mg of THC for infants, which is notably low compared to the dosage found in many cannabis edibles.
Duration of THC Presence in Breastmilk
One of the more concerning aspects of THC in breastmilk is its persistence. Research indicates that THC can remain detectable in breastmilk for up to six weeks after maternal use. This prolonged presence raises questions about the safety of breastfeeding for mothers who consume cannabis, as the cumulative exposure could affect infants over time.
Conclusion
In summary, while THC is present in breastmilk, the concentrations are generally low, and the estimated exposure for infants is minimal. However, the duration of THC’s presence in breastmilk—up to six weeks—highlights the importance of caution for breastfeeding mothers who use marijuana. As research continues to evolve, it remains crucial for mothers to consider the potential implications of cannabis use during breastfeeding.

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.

How long does it take THC to leave your body when pregnant?

Metabolized by the liver, the half-life of THC varies from 20–36 hours in occasional users to 4–5 days in heavy users and may require up to 30 days for complete excretion. In animal models, THC crossed the placenta, producing fetal plasma levels that were approximately 10% of maternal levels after acute exposure.

What is the highest percentage of THC in a strain?

9 Strongest Cannabis Strains

Strain	Type	THC Content
Godfather OG	Indica-dominant Hybrid	Up to 34%
Super Lemon Haze	Sativa-dominant Hybrid	Up to 30%
Strawberry Banana	Hybrid	Around 30%
Kush	Indica (various types)	20-25%

How long after smoking can I breastfeed again?

About 90 minutes after smoking, the level of nicotine in the mother’s blood and milk decreases by about half. Your baby will probably want to nurse frequently in the early weeks, so you may not always be able to wait that long between smoking and the next feeding.

How much THC is in mother’s milk strain?

THC Potency
With a high average THC level of around 27%, Mother’s Milk is a potent strain that experienced consumers will savor.

Are small amounts of THC in breastmilk?

A study by Perez-Reyes and Wall in 1982 suggested that THC is excreted into human breast milk in moderate amounts. Based on their findings, 0.8% of the weight-adjusted maternal intake of one joint would be ingested by an infant in one feeding7 (ie, the baby would receive 0.8% of its mother’s dose/kg).

How much THC is in milk?

Importantly, the researchers discovered that the amount of THC they detected in milk was low — they estimated that infants received an average of 0.07 mg of THC per day. For comparison, a common low-dose edible contains 2 mg of THC.

How much drug goes into breast milk?

Although most medicines are excreted in breast milk to some degree, the amount is usually less than 10% of the maternal dose. Medicines excreted at less than 10% are considered compatible with breastfeeding.

What percentage of THC is in cereal Milk carts?

all of our high potency vapes contain 90% thc or more.

How long do I wait to breastfeed after smoking THC?

This leaves us, I think, with remaining questions and — in my mind — remaining reason for caution about use at all. But there is an important, concrete takeaway: If you do choose to consume cannabis while breastfeeding, waiting 5 to 10 hours after consumption to nurse is a very good idea.
