DEA has since moved their microgram bulletins which had fascinating insights into where the drug world was going from a legal perspective. Does anyone know of some place I can read reports post 2013? Google results show a ton of old stuff but nothing interesting and recent. I posted over at r/drugs a week ago and had no replies =/
You could also always try submitting a FOIA request. IF they are still making said bulletins, they would legally be required to give them to you. Assuming they dont try to get out of it by claiming they are involved with active investigations or something.
