SSRIs increasingly prescribed during pregnancy, without much study on their effects

Lead researcher Claudia Lugo-Candelas
Researchers from Columbia University, the Keck School of Medicine, and the Institute for the Developing Mind in Los Angeles, have published a new study on how infants' brains are affected when their mothers take SSRIs for depression during pregnancy. SSRIs include Celexa, Lexapro, Prozac, Luvox, Paxil and Zoloft, and are used by 1 in 10 adults in the US.

Excerpts from the study:

Selective serotonin reuptake inhibitor (SSRI) use among pregnant women is increasing, yet the association between prenatal SSRI exposure and fetal neurodevelopment is poorly understood.

A cohort study conducted at Columbia University Medical Center and New York State Psychiatric Institute included 98 infants: 16 with in utero SSRI exposure, 21 with in utero untreated maternal depression exposure, and 61 healthy controls. Our findings suggest that prenatal SSRI exposure has an association with fetal brain development, particularly in brain regions critical to emotional processing....To our knowledge, this is the first study to report increased volumes of the amygdala and insular cortex, as well as increased WM connection strength between these 2 regions, in prenatally SSRI-exposed infants.

NIDA Kills Marijuana and Pregnancy Follow-up Study



Culture magazine published an interview this month with Melanie Dreher, the researcher whose 1994 March of Dimes-funded study found that Jamaican mothers who used marijuana bore developmentally superior babies.

A follow up study conducted when the children were 5 years old again showed no negative impacts of marijuana; in fact, they seemed to excel. But no further follow ups could win approval from the US National Institute on Drug Abuse, Dreher reveals. No polydrug abuse was seen in the mothers and very little tobacco or alcohol.

Now dean of nursing at Rush University with degrees in nursing, anthropology and philosophy, plus a Ph.D. in anthropology from Columbia University, Dr. Dreher told Culture, "March of Dimes was supportive, but it was clear that NIDA was not interested in continuing to fund a study that didn’t produce negative results. I was told not to resubmit. We missed an opportunity to follow the study through adolescence and through adulthood.”

In Dreher's original study, nineteen of the 24 Jamaican mothers reported that cannabis increased their appetites throughout the prenatal period and/or relieved the nausea of pregnancy. Fifteen reported using it to relieve fatigue and provide rest during pregnancy.

The study tested 24 Jamaican newborns exposed to marijuana prenatally and 20 nonexposed babies from socioeconomically matched mothers. At one month, the children of marijuana-using mothers scored markedly higher on autonomic stability, reflexes, and general irritability. Babies born to the heaviest smokers, those who smoked every day, at least 21 joints weekly, scored significantly higher in 10 of the 14 characteristics measured, including quality of alertness, robustness, regulatory capacity, and orientation.

It took three years to publish the study in the US; in fact the five-year study was published first. When the NAS Institute of Medicine conducted its $1-million taxpayer-funded study on cannabis as medicine in the wake of Prop. 215, it amended the Dreher study to say the newborns born to marijuana-smoking mothers were equal, not superior. The study has been omitted from other overviews of the topic.

In a recent talk, Dreher lamented the "terrible arrogance and ethnocentrism" that refuses to accept data from other countries, even Europe and Canada. She spoke about the academic world, where "tenure is often more important than truth." Her employers get letters from irate ex-Marines, for example, demanding she be fired.

She also pointed to a 1989 article in the Lancet "Bias Against The Null Hypothesis: The Reproductive Hazards of Cocaine" which found that the rate of acceptance of articles finding negative consequence of cocaine was 57%, versus 11% (only one) for articles that didn't, even though the latter were methodologically superior. Comparing that to the situation with marijuana, Dreher said, "If we looked at all of the literature that hasn't been published, we might find a very different story."

"We have a lot of red herrings," Dreher concluded. She wonders why there are variances within the exposed group, theorizing it could be because of the "impoverished conditions in which women must raise children," looking for cheapest and most available substance to relieve their symptoms and give them the energy to work. Rather than measuring so-called "executive function" in 9-12 year olds, she thinks we should look at a broader picture, including school performance, leadership skills, and the use of tobacco, alcohol and other substances. "We need research on the quality of life -- and how marijuana enhances it," she said.

Dreher did return to Jamaica and found 40 of the children she studied, who now have children of their own and are doing quite well.

Meanwhile, an increasing number of reports from California tell of children being taken from homes of parents who cultivate medical marijuana under state law. Hear this and weep.

If you're as angry about this as I am, write to your Congressional representatives about this outrage.

Studies and Connections

Celebrating Women's History Month, I checked out the Women's Marijuana Movement website, which has lots of good info and links, notably their facts page on marijuana vs. alcohol, their testimonials and links.

On the NORML Women's Alliance site, I found articles and reports on marijuana and pregnancy, breast cancer, and teens. On the "Women and Their Role in Cannabis Culture" page I found this interesting anthropologcial study from Marlene Dobkin de Rios. Both sites have email sign-up lists you can join.

More on the marijuana/running connection raised by Alanis Morisette in an earlier post: Time magazine reports that those who exercise more may crave marijuana less, which fits with recent findings that the runners "high" may be produced by cannabinoids.

A fascinating article in Time interviews researcher Mitch Earlywine, who thinks male pot smokers act dumb because they're told they are, while women want to prove the stereotype wrong.

I'm for that!
