In his 2022 budget proposal, President Joe Biden included a rider first introduced by Republican Maryland Rep. Andy Harris that would block D.C.’s ability to legalize and tax recreational marijuana, even after the city’s residents voted to legalize possession back in 2014. While the budget provision is plainly at odds with Biden’s support of D.C. statehood and autonomy, it’s also the latest example of Biden’s conservative views on marijuana—views that could have major consequences for the climate crisis. Advertisement Currently, because marijuana is not legal at the federal level, cannabis growers are not allowed to ship their products over state lines, as Emily Atkin explains in a recent edition of her newsletter, Heated, aptly titled “Biden’s anti-weed budget is anti-climate.” Rolling Stone dubs weed a “climate villain,” as cannabis sold in any state where it’s legal must be grown in-state. Because not every state boasts the year-round warm climate that cannabis thrives in, the vast majority of cannabis is grown indoors in large facilities. And there are other reasons indoor growing is thriving, as Evan Mills pointed out in a recent Slate piece, from misconceptions about the potency of cannabis grown indoors to budtenders who “tend to toss outdoor-grown product onto the bottom shelf.” Mills argues that the only way to make cannabis truly “green” is to grow it outside.
