My investigation on the cannabis industry for @undark.org — supported by @pulitzercenter.bsky.social — took me from farms in OR to MA testing labs to the OK capitol, uncovering corruption and highlighting change makers along the way. It's quite the ride. Enjoy! undark.org/2025/07/16/c...

Weed Regulation is Foundering. For Answers, Look to the Labs

Lots of legal marijuana is sold with inflated THC levels or unsafe contaminants. Can the oversight system be reformed?

undark.org

If you thought legalizing marijuana for medical and recreational use would make it safer and free of contaminants, think again. Labs cheat and cheating labs get more business, @undark.org reports. The answer is more state-run labs. By @teresacarr.bsky.social Data viz by @aleszu.bsky.social

So much to love in the scrollytelling — the ternary plot, the depth of the data, the findings — but my favourite part is the explanation and the text in general. 📊 Remember, a chart doesn't have to be understood in 3 seconds. It should reward the effort you put into understanding it.

RE: SCOTUS Access to legal counsel seems to be make or break for so many. I mean, who walks around with a habeas petition in their pocket? In a recent article for tracreports.org, I compared how often individuals with different spoken language proficiencies are represented in immigration court.

A point graph entitled Changes in Legal Representation by Language in Completed Immigration Court Cases.
The x-axis is entitled Percent of Cases with Representation. The Y-axis has ten languages in order of relative representation. There are three text annotations.
1. Compared to the previous four years, Arabic-speakers are represented in a smaller share of cases in FY 25...
2. ...while Russian-speakers are represented in a greater share.
3. For both Creole- and Spanish-speakers, the rate of representation has fallen by more than 10 percentage points in FY 25.
