How does one raise awareness about the fragility of marijuana legalization under the watchful eye of President-elect Donald Trump? By handing out 4,200 free joints (roughly 40 ounces, retailing at $8,000) at his inauguration on January 20. The political stand was conceived by Adam Eidinger, the founder of DCMJ, a Washington, D.C.-based marijuana advocacy group. Eidinger, who helped organize the successful fight for marijuana legalization in D.C. in 2014, wants those who get a free joint to simultaneously light up in a mob-like fashion if Trump doesn’t mention support for national weed legalization within four minutes and 20 seconds from the start of his speech.

Though it’s completely legal for adults ages 21 and older to possess less than two ounces of marijuana and consume it on private property in D.C., those who light up at the inauguration, staged at the Capitol’s West Front, will risk arrest for smoking on federal property. It’s also still illegal to buy or sell the drug in the nation’s capital. “If someone wants to do it, they are risking arrest,” Eidinger confirmed. “It’s a protest, and you know what? The National Mall is a place for protest.”

As for the likeliness of national reform, Trump has previously stated that he’s in favor of medical marijuana but wants to let individual states decide on decriminalization. “In terms of marijuana and legalization, I think that should be a state issue, state-by-state,” Trump told the Washington Post. “Marijuana is such a big thing. I think medical should happen, right? Don’t we agree? I think so. And then I really believe we should leave it up to the states.”

If you consider the not-so-fleeting fact that Trump is pro-business and the fact that marijuana sales are performing remarkably well (Colorado did more than one billion dollars in sales last year), federal legalization doesn’t seem out of reach. Vice President-elect Mike Pence, however, is a strong opponent of legal pot, as are many other members of Trump’s cabinet—perhaps most notably Jeff Sessions, Trump’s pick for attorney general.

In April, the Republican senator said, “Good people don’t smoke marijuana. We need grown-ups in Washington to say marijuana is not the kind of thing that ought to be legalized, it ought not to be minimized, that it is in fact a very real danger.”

Social media is having a ball with the campaign, called #Trump420.

So how’s this all going to go down on inauguration day? Time will tell; the only thing we’re certain about is that food trucks are going to kill it that day.
