Ketamine overdose deaths report. Only n=24 from July 2019 to June 2023 as the ONLY drug involved. Yeah ketamine is much safer than a lot of other drugs, but it seems possible there is a max someone should take, especially if physically exerting in other ways.

This came up again today - Is xylazine like krokodil in that they both are associated with skin wounds? No. Xylazine’s wound etiology isn’t super clear yet. But krokodil (which is clandestinely-made desomorphine) causes skin wounds because of a chemical left behind during its synthesis.
