🍄 Episode 6 of A Morel Dilemma is out now. What if the deadly 2023 morel mushroom outbreak wasn’t an isolated event? We examine the evidence, emerging research, and clues that may change how we think about true morel toxicity. 🎧 Listen wherever you get your podcasts.

Can mushrooms we thought we understood start acting differently? In Ep 5 of A Morel Dilemma, we put morels on trial—and detour into wood lover’s paralysis: a bizarre weakness syndrome from certain psilocybin mushrooms that may reveal how new toxic patterns emerge. #fungi #mushroom #mycology

My first publication was on treating an invasive microscopic fungal infection. A decade later, I graduated to macroscopic fungi toxicity: honey mushrooms. Our paper reviews WI cases this beautiful semi-poisonous mushroom. Figure 1 on toxic look-alikes is especially useful! Link below!

Kratom policy varies by state. We looked at poison center exposures by reuglation status. Bans → lower exposure & severe outcomes “Regulation” → looks a lot like no regulation An attempt to provide unbiased data to help inform policy. pubmed.ncbi.nlm.nih.gov/42015466/ #Kratom

One of the fun perks of writing papers: getting consulted about a weird, niche clinical problem… and being able to send the consultee the systematic review you wrote synthesizing all the evidence for exactly how to manage that weird niche clinical problem.

I recently hit my 50th peer-reviewed publication. Not that exciting, especially compared to some people I know. But, I’m not a funded researcher. I do patient care and write in downtime. It’s a lot of nights and weekends spent reading, thinking, and writing.

Since it appears impossible to get people to stop saying Poison “Control” Center can we at least call it a Poison “Command” Center? We don’t command or control anything but maybe I could get a cool badge that way. (🤔Poison Consult Center best option now that I think about it)
