A bipartisan gang of congresspersons are finally banding together to tell this administration that enough is enough. Putting us closer to nuclear war with North Korea out of total ignorance wasn’t enough to draw their ire. Equating white supremacists with anti-racist protesters didn’t do it either. The straw that broke the proverbial camel’s back was made out of hemp.

On Wednesday Attorney General Jeff Sessions received a letter from a group of lawmakers on both sides of the aisle, telling him to knock it off with his meddling in medical marijuana research, as reported by The Cannabist.

According to a Washington Post article, Sessions recently blocked efforts to make cannabis research easier. Medical testing of marijuana is notoriously difficult in the U.S. As of now, the federal government only approves research of cannabis that comes from a grow site in the University of Mississippi.

Not only is this government weed hard to come by, it’s also astoundingly low in quality, topping out at 13 percent THC. A recent study of it found that it was full of yeast, mould, seeds, and stems.

But last year the Drug Enforcement Administration got the ball rolling on reducing the barriers between researchers and good cannabis. Earlier this month, however, an anonymous DEA official told the Washington Post that the Department of Justice, under Sessions, had put a stop to these efforts.

That’s why Representatives Earl Blumenauer (D-Oregon), Matt Gaetz (R-Florida), Jared Polis (D-Colorado), and Dana Rohrabacher (R-California) felt it necessary to tell Sessions and the DOJ that they’re onto their bullshit.

“It is worrisome to think that the Department of Justice, the cornerstone of American civil society, would limit new and potentially groundbreaking research simply because it does not want to follow a rule,” the letter read. “We write to inquire whether the allegations raised by the Post are true, and, if so, to understand the Department of Justice’s rationale in refusing to process these applications.”

You can write a letter to the DOJ too. That’ll show them.
