Senators Chuck Schumer of New York, Ron Wyden of Oregon, and Cory Booker of New Jersey will introduce a plan to legalize cannabis at the federal level later today.

The trio is expected to hold an afternoon press conference to unveil a preliminary “discussion draft” of the legislation, dubbed the Cannabis Administration and Opportunity Act.

Advocates have been awaiting Schumer’s push for federal cannabis decriminalization since the lawmaker hinted at the plans back in 2018.

At the time, Schumer said the legislation would remove cannabis from the list of scheduled substances under the U.S. Controlled Substances Act of 1970, maintain federal law enforcement’s authority to prevent marijuana trafficking from states that have legalized marijuana to those that have not and establish dedicated funding streams for women- and minority-owned marijuana businesses.

He also said it would allow federal regulators to prevent marijuana businesses from targeting children through advertising and make targeted investments in public health to better understand the effects of THC on the brain and the efficacy of medicinal marijuana for specific ailments. It would also provide for highway safety research to ensure federal agencies have the resources needed to assess the pitfalls driving under the influence of THC and develop technology to reliably measure impairment, Schumer said at the time.

The proposed legislation would include social justice provisions, federal taxes and regulations.

In addition to Schumer’s efforts, the House of Representatives has made a push for a similar bill called the Marijuana Opportunity Reinvestment and Expungement (MORE) Act.

However, any legislation on the matter is expected to face an uphill battle as not all Senate Democrats are on board with the proposals, including Senators Jeanne Shaheen of New Hampshire and Jon Tester of Montana. The White House has also expressed that President Biden’s position on the matter “isn’t the same as what the House and Senate have proposed.”

“The president supports leaving decisions regarding legalization for recreational use up to the states; rescheduling cannabis as a Schedule II drug so researchers can study its positive and negative impacts; and, at the federal level, he supports decriminalizing marijuana use and automatically expunging any prior criminal records,” said White House press secretary Jen Psaki. “He also supports legalizing medicinal marijuana.”

According to the National Conference of State Legislatures, 18 states, two U.S. territories and Washington D.C., have legalized marijuana for recreational use to date.

Legal cannabis sales in the U.S. passed $17.5 billion in 2020, an increase of 46% compared to $12.1 billion in 2019, according to Boulder-Colo.-based research firm BSDA. BSDA forecasts U.S. cannabis sales could reach $41.3 billion in 2026.
