Reason published an excellent article on the topic in yesterday's piece: Congress Wants To Give Jeff Sessions Unprecedented New Drug War Powers.
Here are some key excerpts:
If you think the Department of Justice has more than enough tools to wage the war on drugs, a bill passed by the House would create a fast-track scheduling system that could lead to the criminalization of kratom, nootropics, and pretty much anything that gives you a buzz and isn't already illegal.
The House of Representatives voted on Friday to create a new schedule of banned drugs under the Controlled Substances Act, called "Schedule A," and to give Attorney General Jeff Sessions broad new powers to criminalize the manufacturing, importation, and sale of substances that are currently unregulated, but not illegal. The bill is now headed to the Senate, where co-sponsors Dianne Feinstein (D–Calif.) and Chuck Grassley (R–Iowa) will likely have little problem whipping votes.
