Since the President Trump took office and appointed Jeff Sessions as Attorney General, many marijuana advocates have worried about a possible federal crackdown in states where cannabis is legal. But a group of experts said Monday they find it highly unlikely that such a crackdown will take place.

A legislator from Washington, a law professor form Vanderbilt University and an expert from the Brookings Institute spoke to a gathering of the National Conference of State Legislatures on Monday in Boston. They discussed the rumors that the federal government would move against marijuana dispensaries in states where cannabis is legal. However, they said that such a move would be costly, both in terms of money and popularity.

"Trying to roll it back and trying to go back to the old War on Drugs - the terribly failed system - they will do it at their own peril," said Rep. Roger Goodman, a legislator form Washington.

They noted that court cases have barred the federal government from prosecuting marijuana dispensaries if they're following local laws. They also note that the Department of Justice has little resources to enforce the type of mass crackdown that many people worry about

The experts also pointed out that the War on Drugs is becoming increasingly unpopular amongst the American people, and if Sessions were to botch re-igniting the War, it would have significant political ramifications on both the Attorney General and the administration.

Earlier this week, it came out that Jeff Sessions' own task force recommended that the Department of Justice continue its current policy toward states with legalized marijuana. Based on that report and the opinion of these experts, it seems like that Sessions' War on Marijuana may end before it even begins.
