Cannabis legalization and cannabis-involved pregnancy hospitalizations in Colorado | 03/01/2022 | Pregnancy, science direct, Research |
Research has found that prenatal cannabis use may adversely affect fetal growth and neurodevelopment, be associated with future learning and behavioral problems in children, and increase risk of neonatal morbidity. (Cornelius et al., 2002; Day et al., 1994; El Marroun et al., 2011; Fried and Smith, 2001; Fried et al., 1999; Fried et al., 2003; Fried et al., 1997; Goldschmidt et al., 2000; Goldschmidt et al., 2008; Goldschmidt et al., 2012; Metz et al., 2017; Noland et al., 2005; Willford et al., 2010; Ryan et al., 2018; El Marroun et al., 2018) Several US organizations, including the American College of Obstetricians and Gynecologists and the American Academy of Pediatrics, recommend abstinence from cannabis use during pregnancy. (Ryan et al., 2018; Gynecologists, T.A.C.O.O.A, 2020) Despite these recommendations, there are concerns that the trend of cannabis use during pregnancy will continue to increase as more states and countries legalize cannabis and allow for commercial sales through dispensaries.

Maternal Cannabis Use During Pregnancy and Maternal and Neonatal Outcomes: A Retrospective Cohort Study | 02/04/2022 | Pregnancy |
Results Conclusions |
Marijuana Use among Pregnant Women Rises Steeply in Florida | 01/17/2022 | Pregnancy, FDCF, 2022 Marijuana |
Though research among pregnant women and marijuana-exposed neonates is limited, there is evidence to suggest that marijuana use may increase the risk of stillbirth and is associated with neurodevelopmental deficits in the infant. Evidence-based programs to prevent initiation of marijuana use should target women of childbearing age. In addition, THC passes from mother to baby through breastmilk; thus, cessation should continue post-partum.

An Overview of Cannabis Use in Pregnancy | 01/16/2020 | Pregnancy |
Consumption of cannabis during pregnancy results in cannabinoid placental crossing and accumulation in the fetal brain, and other organs, where it interferes with neurodevelopment and the endocannabinoid system. Use during the postnatal period can also lead to secretion in breast milk for extended periods (up to a week) after last use. From retrospective studies, we know prenatal cannabis ingestion has been associated with anemia in the mothers as well as low birth weights, greater risk of preterm and stillbirths, as well as increased need for neonatal intensive care unit admissions. |

Self-reported Medical and Nonmedical Cannabis Use Among Pregnant Women in the United States | 07/09/2019 | Pregnancy, Volkow, PubMed |
Cannabis effects on fetal growth (eg, low birth weight and length) may be more pronounced in women who consume marijuana frequently, especially in the first and second trimesters.4 This study highlights the importance of screening and interventions for cannabis use among all pregnant women. |
Largest brain study of 62,454 scans identifies drivers of brain aging | 05/01/2019 | study, Brain, aging, science daily |
The study found that a number of brain disorders and behaviors predicted accelerated aging, especially schizophrenia, which showed an average of 4 years of premature aging, cannabis abuse (2.8 years of accelerated aging), bipolar disorder (1.6 years accelerated aging), ADHD (1.4 years accelerated aging) and alcohol abuse (0.6 years accelerated aging). Interestingly, the researchers did not observe accelerated aging in depression and aging, which they hypothesize may be due to different types of brain patterns for these disorders. |
Cannabis use during pregnancy: Are we at the verge of defining a "fetal cannabis spectrum disorder"? | 03/10/2019 | Pregnancy, PubMed |
Significant effects of prenatal cannabis exposure have been found on children's sleep, cognitive functions (memory and scholastic skills), as well as on executive (frontal lobe) functions (reasoning, attention, impulsivity, and motivation), and affective (depression) and anxiety symptoms throughout the stages of development. Following the presentation of two case vignettes, we integrate the published information on outcomes of maternal use of cannabis during pregnancy on the developing fetus and the "soft" neurological deficits and neuro-behavioral disturbances manifested by them from early childhood and evolving to peaks in adolescence. Taken together, these data serve to define what we call a heretofore unspecified "fetal cannabis spectrum disorder". |
Is smoking pot while pregnant safe for the baby? | 02/14/2019 | NPR, Pregnancy |
Researchers say psychoactive compounds in marijuana easily cross the placenta, exposing the fetus to perhaps 10 percent of the THC — tetrahydrocannabinol — that the mother receives, and higher concentrations if the mom uses pot repeatedly. |
How Marijuana Exposure Affects Developing Babies’ Brains, Infographic: How Exposure to Cannabis in Utero Affects Development | 01/16/2019 | Pregnancy |
Large-scale, longitudinal studies of humans whose mothers smoked marijuana once or more per week and experimental work on rodents exposed to cannabinoids in utero have yielded remarkably consistent intellectual and behavioral correlates of fetal exposure to this drug. Some exposed individuals exhibit deficits in memory, cognition, and measures of sociability. These aberrations appear during infancy and persist through adulthood and are tied to changes in the expression of multiple gene families, as well as more global measures of brain responsiveness and plasticity. Researchers currently consider these perturbations to be mediated by changes to the endocannabinoid system caused by the active compounds in cannabis. |
Number of new heroin users drops dramatically, but meth, marijuana use up, survey says | 09/16/2018 | Pregnancy, heroin, McCance-Katz |
There was more alarming news. Use of illegal drugs, including cocaine, marijuana, and opioids by pregnant women increased significantly between 2015 and 2017. About 7 percent of pregnant women reported using marijuana. Three percent said they used it daily. McCance-Katz says marijuana use is linked to fetal growth problems, preterm births, stillbirths, hyperactivity and impaired cognition in newborns. |

Committee Opinion No. 722: Marijuana Use During Pregnancy and Lactation | 10/02/2017 | Pregnancy, ACOG, 2022 Marijuana |
There are insufficient data to evaluate the effects of marijuana use on infants during lactation and breastfeeding, and in the absence of such data, marijuana use is discouraged. Notably, 34–60% of marijuana users continue use during pregnancy, with many women believing that it is relatively safe to use during pregnancy and less expensive than tobacco It is difficult to be certain about the specific effects of marijuana on pregnancy and the developing fetus, in part because those who use it often use other drugs as well, including tobacco, alcohol, or illicit drugs, and in part because of other potential confounding exposures. Marijuana smoke contains many of the same respiratory disease-causing and carcinogenic toxins as tobacco smoke, often in concentrations several times greater than in tobacco smoke. Studies of marijuana exposure during pregnancy are potentially subject to reporting and recall bias, often relying on self-reported habits, including frequency, timing, and amount of marijuana use. women using marijuana at least weekly during pregnancy were significantly more likely to give birth to a newborn less than 2,500 Several studies noted statistically significantly smaller birth lengths and head circumferences as well as lower birth weights among exposed offspring |

Parsing the Contradictions: Marijuana and the Brain | 12/07/2016 | Brain, dana foundation, Neuroscience |
“We see specific morphological changes in the brain to important neurotransmitter systems, and individuals who are exposed to THC early in life show greater sensitivity to opiates than others do,” she said. “We know that the brain definitely adapts to marijuana. It is profoundly changing the receptors and receptor signaling that impact gene expression. And the changes it makes last through adulthood and even into the next generation. So we see that there’s something about the ongoing processes in the developing brain that this drug somehow sensitizes—in the cells, the receptors, and in the signaling cascades—that makes kids more vulnerable to addiction and other problems later.” “There is a lot of optimism for what components of the marijuana plant may offer on a medicinal level but, like all other drugs, the caveat is that you have to know what it does, what population it can be used for, and who could be vulnerable to its effects. We need a lot more research before we can say anything concrete about its future as a treatment.”

Marijuana use may be linked to temporarily weakened heart muscle | 11/14/2016 | heart, Studies, Research, American Heart Association |
"This development of stress cardiomyopathy in younger patients who used marijuana suggests a possible link that needs to be further investigated," said Sahil Agrawal, M.D., co-author of the paper and also a chief cardiology fellow at St. Luke's. Marijuana users were more likely than non-users to have a history of depression (32.9 percent vs. 14.5 percent), psychosis (11.9 percent vs. 3.8 percent), anxiety disorder (28.4 percent vs. 16.2 percent), alcoholism (13.3 percent vs. 2.8 percent), tobacco use (73.3 percent vs. 28.6 percent) and multiple substance abuse (11.4 percent vs. 0.3 percent). Because some of these can increase the risk of stress cardiomyopathy, the researchers adjusted for known risk factors to investigate the association between marijuana use and stress cardiomyopathy. |
