Studie: Pränatale Cannabis-Exposition ist nicht mit negativen kognitiven Ergebnissen im Jugendalter verbunden

This got my spider tingling, I figured out what was going on before I even read anything and I turned out to be right.

>“Little evidence emerged for negative effects of low-level prenatal alcohol, cannabis, or combined exposure on adolescents’ cognitive development after accounting for sociodemographic factors,” they determined.

>… No effects persisted after including covariates

Basically they did find alcohol and cannabis did have negative effects but they were able to massage the data enough to „control“ it into non-existence especially since it’s underpowered for what they want. Not statistical significant does not mean no effect.

Always warms my heart when the users of r/science immediately catch on to bad faith articles based on biased research that are posted by lobbyist propaganda bots. 

I have a hard time believing that cannabis use during pregancy would not be correlated with lower cognitive outcomes regardless of if cannabis use was the cause. 

I have two questions. First, the study includes both these statements: “Raw data (pre‐winsorization) revealed, on average, women consumed 8.03 drinks and used cannabis 1.42 times throughout their entire pregnancy.” and “On average, throughout pregnancy, … women who endorsed any prenatal cannabis use reported that they used cannabis on 33.00 occasions.” I’m not understanding why these numbers are different. In their cohort, did women who used cannabis during pregnancy use it on average 1.42 times total, or 33 times total? That’s a big difference.

Also a huge buried detail: “Children with especially poor cognition (e.g., severe learning disorder and intellectual disability) were excluded from the ABCD sample. Therefore, results are only generalizable to children within the typical range of cognitive development.” **The conclusions of this study is not nearly as broad as the headline appears. It *excluded* children with severe learning disabilities and particularly poor cognition.** So it says nothing about whether prenatal alcohol and cannabis use cause more severe cognition issues. IF the child is in the normal range, there’s no observable difference (according to this study). That’s a big “if” and pretty wild it’s buried halfway through the study.

This is the best news I’ve hear of this year!

Of course it bloody does. It’s highly psychoactive and long term use causes memory loss which is indicative of an undesirable change or is causing toxicities (literal brain damage) in your neurological makeup. You don’t need a nonsense study to figure out that if the mother ingests cannabis then it goes in to the placenta and then in to the baby. A baby is tiny so will obviously be affected greatly.

Maybe a very rare joint would be safe but chronic use will most definitely affect the foetus. The mother’s diet and stress levels affect the baby so why on earth would cannabis NOT affect the baby.

I’m not a professional but it doesn’t require a degree to figure that one out.
