John Boehner is joining a marijuana company

The legalized-marijuana movement will likely welcome the news Wednesday that two prominent former politicians are joining a cannabis company.

John Boehner, former Republican speaker of the House of Representatives, and Bill Weld, a former Republican governor of Massachusetts who was the 2016 running mate of Libertarian presidential candidate Gary Johnson, are joining the advisory board of Acreage Holdings, which owns cannabis licenses and assets in the 30 states where cannabis is approved for medical or recreational use.

Boehner tweeted that he was making the move because his thinking on cannabis has evolved, and that treating it more leniently under the law could help in the battle against America’s opioid crisis.

As cannabis gains acceptance — 94% of Americans currently favor some type of access, according to a joint statement from Boehner and Weld — more parties are calling for it to be de-scheduled and free up companies to engage in research and development.

With Canada gearing up to fully legalize marijuana this summer, there are concerns that U.S. companies will lose out on capturing a share of a market expected to generate billions in sales, and that states will lose a valuable source of tax revenue.

“While the Tenth Amendment has allowed much to occur at the state level, there are still many negative implications of the Federal policy to schedule cannabis as a Class 1 drug: most notably the lack of research, the ambiguity around financial services and the refusal of the VA to offer it as an alternative to the harmful opioids that are ravishing our communities,” said the statement.

The industry is facing one major obstacle in Attorney General Jeff Sessions, a longtime cannabis opponent. In January, Sessions rescinded an Obama-era policy used as a protection for states that have legalized marijuana.

The Justice Department scrapped what is known as the Cole Memo, a four-page document written by Obama-era Attorney General Eric Holder’s office that outlined how the federal government would enforce marijuana laws, stating that Washington would not interfere with states that legalize recreational and/or medical marijuana, as long as they adhere to a set of guidelines.
