yesterday I was recrystallizing some old spice and I had one small stash of some white/clear shards I had extracted from acrb that I had done a Sodium carbonate wash on my combined pulls that I had extracted in 2014. I remember this batch because I had gently scraped the shard from the top of a layer of sugary goo and set them aside. I made changa from the goo that was good but had only smoalked the shards once. Yesterday they were as shiny as they were 4 years ago! Yellow mhrb from last year was already taking on a deeper orange tint.
The bioessay of the 4 year old spice was Easy breakthrough at 40mg in the GVG. It was so smooth I wasn't sure I had even gotten anything until halfway into hold the first of 2 hits. By the time 2 was taken I was a goner lol.
