The body makes cannabinoids of its own. These signalling molecules are not the same as substances from the cannabis plant.
A signalling system you already have
The endocannabinoid system is part of communication within the body. The NIH describe its involvement in processes including mood, memory and pain perception. It also exists in people who have never used cannabis.
The system includes signalling molecules, receptors and enzymes. Anandamide and 2-AG are two well-known endocannabinoids. CB1 and CB2 are among the receptors involved in signalling. Enzymes help produce and break down the body’s own molecules.
Endocannabinoids are not CBD or THC
“Endo” means originating within the body in this context. CBD and THC come from the cannabis plant and have different properties. Being discussed in connection with the same system does not make substances identical or their effects equivalent. The existence of this system does not itself establish a need for additional CBD.
What has been found in breast milk?
Researchers have examined endocannabinoids and related lipids in human milk. A 2018 study analysed milk from 24 women and identified several of these substances. A 2021 study detected 2-AG, while anandamide was below the method’s detection limit. Sampling and storage also matter when interpreting measurements.
These studies concern naturally occurring milk constituents. They do not show that breast milk normally contains THC from cannabis, or that babies need CBD. The precise roles of these substances remain under investigation.
Natural does not mean risk-free
The findings are not an argument for cannabis use while breastfeeding. The CDC advise breastfeeding mothers to avoid cannabis, including CBD, because of potential risks to the infant. Discuss medicines during pregnancy and breastfeeding with a clinician or midwife.
Curiosity with clear limits
It matters to distinguish measured findings from conclusions that remain uncertain. This article explains research, promotes no specific commercial products and is not a treatment guide.
