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. |

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. |

Marijuana use in early adolescence may affect verbal IQ | 01/24/2017 | IQ, youth usage, Brain |
"The study suggests that the effects of cannabis use on verbal intelligence are explained not by neurotoxic effects on the brain, but rather by a possible social mechanism," said lead author Natalie Castellanos-Ryan, Assistant Professor at Universite de Montreal in Canada |
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. |

Adolescent Cannabinoid Exposure Induces a Persistent Sub-Cortical Hyper-Dopaminergic State and Associated Molecular Adaptations | 01/04/2016 | Brain, adolescent, Research |
Thus, adolescent THC exposure induced behavioral abnormalities resembling positive and negative schizophrenia-related endophenotypes and a state of neuronal hyperactivity in the mesocorticolimbic dopamine (DA) pathway. Furthermore, we observed profound alterations in several prefrontal cortical molecular pathways consistent with sub-cortical DAergic dysregulation. Our findings demonstrate a profound dissociation in relative risk profiles for adolescent versus adulthood exposure to THC in terms of neuronal, behavioral, and molecular markers resembling neuropsychiatric pathology. |

Mother's and marijuana use | 10/01/2015 | NIDA, Pregnancy, vidoe, Dr. Genna, Dr. Natacha, interview |
My main finding is that it's primarily women who were younger when they become mothers who do continue to use marijuana overtime. Also women who are depressed over longer periods of time, women who smoke, women who use more than the recommended amount of alcohol are more likely to continue to use marijuana while pregnant as well as when they're raising their children. So the take-home messages is to ask women about marijuana use. We know that marijuana use is considered more and more acceptable by women and that they may continue to use while they are pregnant and while they are having children. |
