Tim, Sam and Peter explore the differences and the similarities between life and work in the Forensic and Clinical branches of Toxicology and the opportunities collaboration can bring.  And sadly TIm bids farewell to the Toxpod as he explores new opportunities. Thank you Tim for coming up with the idea of the Toxpod and all the hard work you've done! You will be missed!
