Ryan Feldman PharmD DABAT @empoisonpharmd.bsky.social · 08/07/2026🍄 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. 000
Ryan Feldman PharmD DABAT @empoisonpharmd.bsky.social · 24/06/2026Can 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 010
Ryan Feldman PharmD DABAT @empoisonpharmd.bsky.social · 19/06/2026This rules The response to A Morel Dilemma has been genuinely overwhelming, especially from people in mycology, foraging, toxicology, and public health.

Ryan Feldman PharmD DABAT @empoisonpharmd.bsky.social · 15/03/2026One 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. 021
Ryan Feldman PharmD DABAT @empoisonpharmd.bsky.social · 12/03/2026I am glad I have taken the time to write, because its an investment in myself. So here is to 50 more. 010
Ryan Feldman PharmD DABAT @empoisonpharmd.bsky.social · 12/03/2026Writing has been one of the best ways I’ve found to explore my own thinking. And sometimes it helps someone else too, whether it’s a clinician at 2 AM facing something for the first time, or someone with a clinical quandary looking for data to push them one way or the other. 110
Ryan Feldman PharmD DABAT @empoisonpharmd.bsky.social · 12/03/2026Sometimes people joke that I bring citations to the bedside. But that’s because I’ve already wrestled with those questions while writing, and digging for answers related to outcomes, and finding the citations to support it. I bring that evidence with me when caring for patients. 110
Ryan Feldman PharmD DABAT @empoisonpharmd.bsky.social · 12/03/2026I’ve never learned more than when I force myself to put an idea on paper, unchangeable, no backpedalling. You explore it deeply, and cite the evidence to prove (or disprove) it. This forces me to "find my receipts" for what I know and helps build my library to show others. 110
Ryan Feldman PharmD DABAT @empoisonpharmd.bsky.social · 12/03/2026Not only do I get the thrill of “discovering” something new by putting data behind a clinical decision point that once felt uncertain (yes, it’s genuinely a thrill). But more importantly writing forces me to pressure-test my own thinking. 100
Ryan Feldman PharmD DABAT @empoisonpharmd.bsky.social · 12/03/2026Some colleagues honestly raise an eyebrow at it. Why sink that much time into papers that sometimes get read by 1–2 people? Fair take. But the biggest winner of writing/researching has always been me. 111
Ryan Feldman PharmD DABAT @empoisonpharmd.bsky.social · 12/03/2026I 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. 230

Ryan Feldman PharmD DABAT @empoisonpharmd.bsky.social · 16/06/2025Yes! And dose makes the poison, just one data set of many. But I do think it’s reassuring in some aspects, I think I would still be worried in more than one cap and in larger mg/kg ingestions. 110
