It’s funny how, when Black people leave toxic church spaces we are the ones called “divisive.” We always have to bear the weight of judgment and have to explain ourselves.

When you see Black people leaving a predominantly white church space en masse, you should be asking...

1/14 How do e-cigarettes (ECs) affect cigarette smoking among youth? My new paper with @FloeFoxon simulates each scenario and finds out which one best matches actual trends... https://t.co/dBB7kcnTls @jgitchell @mikepesko @SwitchFinder @jkelovuori @TobPolicy @Clive_Bates

2/14 First, let's talk about why this question is so difficult to answer: COUNTERFACTUALS. We can't know the alternate-reality answers, like which smokers would have never started in a world without ECs, and which nonsmokers would now be smoking without ECs as an option.

3/14 So, the best we can do is use fancy/sophisticated methodologies to estimate what would have happened to youth smoking rates in the absence of ECs. In our case, simulation modeling

4/14 First, we look at the declining smoking trends *that were already happening* before ECs came (~2010), and project them into the present. This is our BASE-CASE SCENARIO about what smoking trends would be if ECs were never invented. Actual trends were LOWER than this base-case

5/14 Side note about terminology: We use the term “catalyst” instead of “gateway,” because “catalyst” is more precise about the claim we are modeling (that ECs are used first, and then causally lead to smoking). Whereas "gateway" can include other mechanisms like renormalization.

I’ve just finished some research about the use of biosolids (human sewage sludge) as farm manure. The results will keep me awake at night.
¾ of biosolids in the UK are spread on farmland. The rules about what it can contain are not fit for purpose. Please read and share this 🧵

Biosolids typically contain a wide range of synthetic chemicals, including antibiotics and other pharmaceuticals, personal care products, microplastics and persistant organic pollutants, among them “forever chemicals”. Yet testing is restricted to a small number of contaminants.

Spreading them across the land means spreading them through the foodchain and the ecosystem. There’s plenty of evidence of uptake of many of these chemicals by crops, earthworms and other soil animals, and of large-scale antibiotic resistance developing among soil bacteria.

When soil is blown or washed off the land, these chemicals enter the air and water. Some seep into groundwater. We're likely to eat, drink and breathe them. It’s hard to say what the health thresholds are, or what the combined impact of this cocktail of synthetics might be.

Yet the issue has been wilfully neglected by governments. Regulation is negligible. Farmers in the UK are “responsible for knowing the levels of any potentially toxic elements” before spreading sludge. But how? With an on-farm lab that can test for 80,000 possible contaminants?

Yesterday I refused unsafe work. This is how it went.

1st, to the haters. Since when is it "normal" to go to work scared for your health, your life, and your family's lives? It is our right not be scared at work and our employer (in my case, the gov) needs to put measures in place so we aren't afraid. That is law, not just words.

There were 2 steps to the refusal. Refusing to work to my employer, and refusing to work to the Ministry. If my concerns were addressed in Step 1 - to my employer, there is not need to go to the Ministry. We went to the Ministry.

Involved in my refusal were my administration team, a Health and Safety Inspector from my employer, a Health and Safety Inspector from my union, and later in Step 2, a Ministry of Labour Inspector.

I first stated my specific concerns to my adm. They were so supportive in doing everything in their power to address my concerns. I want to thank them for that. They took my concerns seriously. My concerns were all tied to the increased contagiousness of the new variants:
