Subject: THC in breast milk
Dear Lactnet Friends:
Thank you Debbie for sharing these abstracts.
The one about THC staying in breast milk is annoying, because it will
reinforce value-based practice.
Just because THC is present in the body does not mean the person is
intoxicated. This is the huge flaw in testing for THC; a person ingests a
THC compound, is intoxicated for a while.....and then the intoxication
passes. But the THC can show up in a test in the body for up to a month
after the one-time use, depending on one's metabolism and body fat.
While no one encourages smoking ANYTHING in pregnancy, the research does
not often distinguish between edible and smoked varieties of THC.
When one examines the impact of smoking tobacco in pregnancy on babies,
that impact is similar to the impact of smoking cannabis in pregnancy on
the babies. So is it the substance or the smoking that is the problem?
Research tells that smoking reduces placental blood flow.
Based on the research, the use of antibiotics in labor is far more
compromising to future health of the infant than THC in breast milk. More
studies are being published about the gut microbiome and its impact on
autoimmune disease, autism and obesity. Here's the latest:
"In many resource-poor countries, bifidobacteria are the dominant fecal
microbes in breastfed infants (1–3), whereas in resource-rich countries
there is marked variability, with some studies showing low numbers of fecal
bifidobacteria among breastfed infants (4–6). Infant delivery mode, diet,
and maternal fecal bifidobacteria influence infant colonization with
bifidobacteria. Decreased numbers of intestinal bifidobacteria have
clinical relevance, based on a large body of evidence that intestinal
dysbiosis early in life predisposes to inflammation, and increases risks
for obesity, atopic and allergic diseases, inflammatory bowel disease
(7–9), and diabetes mellitus (types 1 and 2) (6, 10). It is not likely
coincidental that dysbiosis-associated diseases are markedly less common in
resource-poor countries."

My point is that the research showing that THC in breastmilk is harmful to
the infant has not yet been found. From LACTMED: "Because of insufficient
long-term data on the outcome of infants exposed to cannabis via
breastmilk, health professionals' opinions on the acceptability of
breastfeeding by cannabis-using mothers varies. In general, professional
guidelines recommend that cannabis use should be avoided by nursing
mothers, and nursing mothers should be informed of possible adverse effects
on infant development from exposure to cannabis compounds in breastmilk. In
addition to possible adverse effects from cannabinoids in breastmilk,
paternal cannabis use may also increase the risk of sudden infant death
syndrome in breastfed infants. Cannabis should not be smoked by anyone in
the vicinity of infants because the infants may be exposed by inhaling the
smoke.[6 <https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.ncbi.nlm.nih.gov%2Fbooks%2FNBK501587%2F%23&data=04%7C01%7C%7C6f32428873fc48e5eaed08d8f068344e%7C84df9e7fe9f640afb435aaaaaaaaaaaa%7C1%7C0%7C637523677637114425%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=WymRy0CeJnKKWFiLPdRdmLRwy4IPneoCnw8c%2BEWRynM%3D&reserved=0>-9

The research showing that the impact of delivery practices (i.e. cesarean
section), formula feeding, and use of antibiotics on the infant gut
microbiome (and future health) is growing.
Shouldn't the public be made aware of the dangers of routine cesarean
section (31% in the US today), formula use, and routine antibiotics?
warmly,
