The Hailey Public Library’s favorite forensic chemist Cat Helms takes a look at cicutoxin, the poison found in water hemlock, in the popular Pick Your Poison series. Common along small ditches and wet meadows in Blaine County, it is considered the most violently toxic plant growing in North America. Learn how to identify water hemlock, the mechanisms by which it wreaks havoc on the central nervous system, and what to do if it is accidentally ingested or touched. The free talk will be held at Town Center West, 116 S River, Thursday, June 8, from 5:30-7:00 PM.
