That's not actually what the study found. Further, cessation of cannabis use did not fully restore neuropsychological functioning *among adolescent-onset cannabis users*. They did not find a 6-8 point decline for folks who gave up cannabis if they started later in life. In fact they found no decline in IQ whatsoever for folks who started later in life - both when using it and after stopping. In contrast, within-perso…

I don't think my summary was unfair. I was only asked if there was evidence for persistent effects. There clearly is, even if just for adolescents. It's also important to point out that for the adult-onset group they only looked at 1 year back. This doesn't preclude the possibility that longer periods as an adult find different results.

It makes me angry to think of how wreckless the generations before millenials were. Lead's risks and damages were well-known long before 1996. And they still didn't ban it until then.

were no better these days with pfas, bpa, bps, badge, phthalates, etc.

And we still have supplements and pots and pans that have lead in them, along with other heavy metals.

Same goes for sugar. We know the dangers it poses, we are also seeing how much it increases risk of death due to covid. I don't think we should be surpsied, as much as pushing to regulate this garbage. As an aside, Michelle Obama's campaign when Obama was in office was about improvement children's health.

> As an aside, Michelle Obama's campaign when Obama was in office was about improvement children's health. Her focus was going to be on nutrition (lunch food). Shortly thereafter Coke and Pepsi came in with "donations" and the whole thing became about exercise, no focus on nutrition. This isn't accurate. There were changes to the school lunch program, and by most accounts they were pretty effective: https://sph.washi…

The rollback they did in 2020 is ridiculous.

My kids school lunch now is all packaged sugary crap. Corndogs, cinnamon buns for breakfast, Trix yogurt, etc. Even the milk is gross - lowest bidder swill that tastes like wax.

The hot food items are all oven-baked, in plastic wrappers. It’s essentially the same crap that you would see in a university vending machine.

Same for industrial seed oils. We know it's dangerous.

But monied interests and some vegetarians who think all things that come from plants must be good for you, prevent this from being shoved into near all packaged foods.

Adding this to the list of things IQ tests accurately predict: 1) school performance 2) job performance 3) income 4) crime rate 5) health and mortality 6) quantity of lead exposed to 7) NOT intelligence

>3) income Hm, I know some obvious contradictions. Just saying.. not interested in discussing this.

Individual cases do not invalidate statistical trends...

Fluids consume large amounts of shelf space by volume regardless of what fluid it is, not much we can do about this, so a large amount of shelf space does not mean a large percentage of the store's total items, in theory. By percentage of total items, it's likely very small for most supermarkets. See also the large amount of shelf space typically required to stock bottled water and soft drinks.

The variety of alcohol on offer does seem a tad perverse, in a way that status quo bias renders difficult to perceive. How many brands of bottled water do you usually see? Half a dozen, tops? And much of the volume in that aisle is occupied by huge 16-packs and giant carriers. Meanwhile the average wine aisle has hundreds of different brands, nearly all no more than 75cl, and might even stretch to two aisles in a lar…

I don't think the number of brands on offer has any effect on our relationship with booze. It doesn't matter how many brand of yellow mustard are on the shelf, I'm buying it at the same rate. Where I live now, very few super markets have beer/wine and none have spirits. I know I buy less booze now than I did when I lived in places where you could get beer pretty much anywhere, at gas stations, super markets, convenience stores, etc., and it's probably for this reason.

Lead still isn't banned in the US. You can go buy 100LL and burn it in your plane all day long showering it over the land below. Completely legal.

yeah i live under the flightpath of a lot of flight school traffic and this weighs a bit on my mind. pretty busy flight area too. Who knows the damage really? are there tests you can take?

If it is larger jet planes, you're mostly safe. Those burn lots of fuel, but it is "jet fuel" which is more like kerosene or diesel.

There are a lot of things wrong with this take that others have pointed out, but for some reason no one noted that as the article points out, the people most impacted by this were born in the late 60s and 70s, and those people are Gen X. We didn't choose this, we just suffered for it. Someone born in 1976 didn't vote until 1994.

Wait until everyone finds out about what COVID is going to do...

Aye, in twenty years when we fully understand long covid a lot of people are going to regret not putting in the blood sweet and tears to convince ignorant family members that the vaccine is actually a good thing. We're also going to probably look back on the lack of continued remote learning as a dire mistake.

You can’t ban everything… Marijuanna and sugar and a million other potential vices like alcohol and video games should be available. But we should teach kids discipline, critical thinking, and impulse control - rather than playing whack-a-mole with every vice that comes along.

as we're a society increasingly made up of single parents with a poverty of energy and time. not to mention their own education on these matters.
