Psychedelic Use During and After Pregnancy
Talking about psychedelics and pregnancy is a sensitive topic. Some equate mentioning psychedelics here with recommending alcohol or cigarettes to pregnant women; others promote their traditional or health-based use. Yet safety concerns and cultural taboos make this a challenging subject, demanding evidence-based guidance. As psilocybin and other psychedelics gain attention for mental health and wellness, more people are asking about their use during pregnancy and after birth while breastfeeding. Despite growing interest, we face major gaps in our understanding—across both clinical research and cultural practice. To serve women best, we must address these gaps with evidence, curiosity, and empathy.

Why Would Women Consider Psychedelics During Pregnancy or Breastfeeding?
Mental health challenges, depression, and anxiety often lead women to take psychiatric medications during pregnancy. Rising birth trauma and postpartum depression remain tragic and complex, affecting not just mothers but also their babies. Postpartum depression (PPD) impacts up to 1 in 8 women, leading to persistent sadness, fatigue, and difficulty bonding, which can undermine wellbeing and daily functioning for mothers and families. Children of mothers with untreated PPD are at increased risk for cognitive delays, behavioral issues, and insecure attachment, with effects that can persist, influencing their mental health risks going forward. Early clinical studies show that psychedelics may help with postpartum depression [1] ; however, mothers have typically been required to stop breastfeeding to participate, a trade-off many view as harmful in itself. Some women struggling with substance use disorders find psychedelic therapy helps reduce cravings – potentially reducing harms from alcohol or opioids during pregnancy, where risk to infant health is well established.
Indigenous Knowledge: Insights from TraditionIndigenous Knowledge: Insights from Tradition
Indigenous communities have long histories of using plant medicines, including psychedelics, in maternal care. Among various Amazonian groups, ayahuasca—rich in DMT—is sometimes used in pregnancy under ritual guidance. Central American traditions have documented psilocybin use by pregnant women, while in some North American Indigenous groups, peyote (mescaline) appears in ceremonies involving pregnancy. Reasons for use vary: in some traditions, early-pregnancy psychedelic use was believed to test the viability of the pregnancy; miscarriage signaled that the pregnancy was not “strong” enough. More commonly, psychedelic plants like ayahuasca or mushrooms are used later in pregnancy or even during childbirth, guided by elders or female relatives and embedded in strong social support. In the Santo Daime tradition in Brazil, small doses of ayahuasca are shared in the final month to support relaxation, pain relief, and the sacred spiritual journey of birth. Elsewhere, mothers may use psychedelics postpartum or while breastfeeding, and—though rare—some cultures have even anointed newborns with ayahuasca to formally welcome them. These practices always reflect a careful balance of autonomy, spiritual meaning, safety, and strong community safeguards [2 – 5 ]
These traditions hold important insights for research. Understanding their origins and outcomes helps illuminate both potential risks and overlooked benefits. However, traditional use must always be contextualized; what holds meaning within one community might not be safe or appropriate in another.
Lived Experiences: Survey Insights
A 2024 survey, “Mothers of the Mushroom,” polled over 400 mothers who used psilocybin mushrooms during pregnancy or breastfeeding. About 43% used them while pregnant, and 57% during lactation, with no deaths reported. Most sought support for mental health or spiritual wellbeing, preferring natural options over pharmaceuticals. Reported benefits included increased patience, emotional stability, and improved family connection—as summed up by one: “I was able to laugh and play with my children when before I was a depressed couch potato.” For 14 reported pregnancies, outcomes matched national averages; most babies were born full term and healthy. Dosing was mostly microdoses (<0.3g), prepared as capsules, teas, or similar forms [6].
But there are limitations: these surveys are self-selecting and retrospective, likely over-representing positive stories and missing those with poor experiences.
Backing this, Amanda Elmore’s 2025 study (N=94) found that 96% of mothers using psilocybin during or after pregnancy reported improved mental health, such as less depression, anxiety, or PTSD. Over half (55%) preferred microdosing to stay present as parents. The study underscores potential, but urges caution, given unknowns in breastfeeding safety, small sample sizes, and self-report bias [7].Such work deserves more support. Meanwhile, acute risks cannot be ignored—other medical literature highlights that infants are especially vulnerable to exposures via lactation [8].

Listening deeply to women’s experiences and combining rigorous scientific evidence with insights from cultural and community knowledge will lead to better support for families.
Where Research Falls Short / Setting a Research Framework
Solid research and ethical safeguards must always precede clinical change. Studies on psychedelics in pregnancy should ensure true informed consent, account for hormonal changes, and be sensitive to cultural context. The best research teams bring together obstetricians, midwives, psychiatrists, Indigenous advisors, and policy experts. Including pregnant people in research is about justice, not just evidence. Early, careful observation – not just intervention – will help avoid repeating mistakes of the past.
Less than 40% of U.S. clinical trial participants are women, and fewer than 1% of drug studies enroll people who are pregnant [9]. This leaves critical gaps in understanding medication safety, and most trials fail to consider the impact of hormonal cycles, pregnancy, and menopause on drug effects. Caution is vital, but rigid exclusion only deepens inequities – especially for already marginalized women. We need comprehensive studies to weigh both risk and benefit in these sensitive windows [10]
“Do no harm must remain our guiding light—especially as psychedelics expand their therapeutic reach…we must shift from risk aversion to responsibility, curiosity, and care.”
Microdosing vs. Large Doses
A microdose is just a crumb – about 0.1 to 0.3 grams of mushrooms, far below the amount needed for a full experience. A large dose is a big leap – usually 2 grams or more for a full psychedelic journey. Large doses can cause profound mind-altering effects and greater fetal or infant exposure. Microdosing’s risks are simply unknown: while popular, there’s no firm evidence that it is “safer” or that repeated small exposures during pregnancy or breastfeeding are benign.
What Animal Studies Tell Us
Animal studies suggest psychedelics cross the placenta [11]. This, along with likely transfer into breastmilk, points to real caution – yet rodents are not humans, and we’re only beginning to unravel the risks. Effects may vary with timing and dose, but periods of rapid infant brain development are especially vulnerable.
What Needs to Happen
Research must partner with affected communities – including Indigenous groups and grassroots mothers’ networks – while tracking both dose and frequency, and following children through to adulthood. Future studies should gather more nuanced, culturally informed data, and policy should support robust participant protection.
Understanding if and how psychedelics get into breastmilk is vital. Women should have clear guidelines, as exists for alcohol, ensuring mothers seeking psychedelic therapy can make informed choices about when to safely feed their infants. More knowledge will allow women to access potentially life-changing treatment without risking breastfeeding’s benefits.
Final Thoughts
Pregnancy heightens awareness and empathy, and all research should reflect that reality. Listening deeply to women’s experiences and combining rigorous scientific evidence with insights from cultural and community knowledge will lead to better support for families. Responsible, inclusive research and clear communication help ensure safer, more empowered health choices – without resorting to fear or stigma.
But at the end of the day, every person who is struggling – whether with depression, anxiety, or other difficulties – faces real decisions between alternatives. If someone isn’t feeling well, there’s never only one path forward: options range from doing nothing, to standard therapies (like SSRIs), to exploring integrative or emergent modalities such as psychedelics.
With antidepressants such as SSRIs, we have decades of accumulated research. This allows women and clinicians to weigh comprehensive data when considering both the risks – to parent and baby – of treatment versus the risks of untreated illness. For example, though SSRIs are more studied and widely prescribed, some research suggests there are possible effects on babies in utero, prompting careful, individualized risk assessment and robust informed consent processes. The ability to compare these medications to “doing nothing” or to counseling or holistic supports is critical: with established treatments, we can make decisions that are grounded in known risks and benefits, not guesswork.
With psychedelics, we are not yet even at the testing stage for pregnancy and breastfeeding – the landscape is one of hope, but also of major unknowns. This means women who are struggling deserve transparency about the gaps: not just what evidence is missing, but what those absences mean in real clinical risk and choice. It is not simply about weighing “psychedelics versus nothing” – it is a matter of comparing these substances against all available evidence-based treatments, understanding the knowns and unknowns, and always returning to the root question: “Compared to what?”.
Do no harm must remain our guiding light – especially as psychedelics expand their therapeutic reach. We now see, for instance, that increased cannabis use during pregnancy (after medicalization and decriminalization) is linked to unexpected risks for children’s psychiatric health, reminding us what can happen when we move faster than the evidence.
Pregnancy should not be pathologized; it should be honored as a period of heightened relationality and responsibility. Through research, understanding, and respectful engagement, we may discern how psychedelics could genuinely alleviate maternal distress within a holistic and culturally sensitive framework. To avoid leaving women with a dangerous vacuum – where advice is shaped more by belief than understanding – we must shift from risk aversion to responsibility, curiosity, and care.
