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?

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...

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.

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.
