It's allowed in Colorado, Vermont, Oregon, Washington, and California, so definitely becoming more widespread. I'm not sure if you need a specific mortuary, but the one I worked in Colorado (before the law passed) would work with all sorts of programs; Science Care (body donation), organ donation programs, the companies that turned your cremated remains into diamonds/glass art/coral reefs, the ones that shot cremated remains into space or had it mixed with fireworks or tattoo ink. There are a LOT of options for you postmortem 😅
