A hazy legal landscape means people can get high on hemp products, even where pot is prohibited The 2018 farm bill legalized hemp products that offer a high similar to marijuana nationwide. Experts worry that lax regulations present a public health risk.

My occasional reminder to folks on tenure and promotion committees that there will be a cohort of people whose early careers were defined entirely by the pandemic and *waves vaguely* this nonsense, and it *will* impact their productivity.

It can't not.

Clearing the air A hearty welcome to all the new AQI obsessives!

As someone who writes and thinks about air quality all the time, I wanted to answer some questions I'm getting and talk about what steps I'm taking, not necessarily as a reporter, but as an LA mom trying to do the right thing

The Fires: Air Quality, Public Health & What to Do Next YouTube video by Coalition for Clean Air

Those in LA:

I attended a webinar hosted by the Coalition for Clean Air. We heard from environmental scientists about air quality concerns from the LA wildfires. I found it both informative and bleak. But knowledge is power, so sharing the link to the recording. m.youtube.com/watch?v=gdHM...

FDA Proposes Significant Step Toward Reducing Nicotine to Minimally or Nonaddictive Level in Cigarettes and Certain Other Combusted Tobacco Products FDA issued a proposed rule that, if finalized, would limit the level of nicotine in certain combusted tobacco products.

HUGE news in tobacco control. I’m seeing a lot of comments saying this will lead to people smoking more cigs to attain the same nic hit, but that’s just not what the science tells us. Models show this rule could result in 12.9 million people quitting in just 1 year.
