I was just wondering what the shelf life of root bark is. Does it ever diminish in quality? I would also like to know if the DMT I have will ever expire. I havn't been using it, and I still have a bunch of powdered root bark that I intend to extract with but havn't found the time. I want to get back into my journeys but now is a bad time for me. So I'm just wondering if I come back to it; extracting from the root bark and smoking my existing DMT in say a year, would they still be the same?
