Gov. Charlie Baker is blasting Attorney General Jeff Session's call to rescind an Obama-era policy allowing states to pursue legalized pot, and the attorney general and state marijuana regulators said today they still intend to implement the Massachusetts law.

“The administration believes this is the wrong decision and will review any potential impacts from any policy changes by the local U.S. Attorney’s Office,” said a spokesman for Baker.

The spokesman added that the Republican governor, who had opposed legalizing marijuana in 2016, “fully supports the will of the voters.”

Sessions' decision, reported this morning by The Associated Press, is expected to be officially announced later today. The AP cited two people with knowledge of the move, which may immediately create confusion about whether it’s OK to grow, buy or use marijuana in states where it's been legalized.

Attorney General Maura Healey said her office is committed to backing state marijuana regulators, towns and law enforcement to ensure the state law is implemented “effectively.”

“Today’s announcement from Washington inexplicably directs federal law enforcement resources away from combating an opioid epidemic that is ravaging our communities in order to focus on legalized marijuana,” Healey said in a statement.

The Massachusetts Cannabis Control Commission, the five-member panel created last year to oversee the state's new law, said its role “remains the same.”

“As far as the mandate and the work of the Cannabis Control Commission is concerned, nothing has changed,” the commission's statement said. “We will continue to move forward with our process to establish and implement sensible regulations for this emerging industry in Massachusetts."

Federal law still prohibits the sale and use of marijuana, but former President Obama had cleared a path for states to legalize it. A memo, written by then-Deputy Attorney General James M. Cole, cleared up some of the uncertainty about how the federal government would respond as states began allowing sales for recreational and medical purposes.

It's that directive Sessions intends to rescind, instead allowing U.S. attorneys across the country decide what kinds of federal resources to devote to marijuana enforcement based on what they see as priorities in their districts, according to the AP.

Andrew Lelling, President Trump's newly tapped U.S. Attorney for Massachusetts, said in a statement he will "continue to pursue federal marijuana crimes, especially bulk trafficking."

Lelling also sought to defend the Department of Justice's focus on marijuana, arguing that it doesn't impact his office's efforts on battling the opioid crisis.

"As with all of our decisions, we will continue to use our prosecutorial discretion and work with our law enforcement partners to determine resource availability, weigh the seriousness of the crime and determine the impact on the community," Lelling said.

"As the Justice Department has highlighted, medical studies confirm that marijuana is in fact a dangerous drug, and it is illegal under federal law," he added. "As a result, our office will continue to investigate and prosecute bulk cultivation and trafficking cases, and those who use the federal banking system illegally."

At the state level, the Cannabis Control Commission said it intends to “fulfill the will of the voters” who passed legalized marijuana in a 2016 ballot question.

“Our priority has always been to protect public safety and develop regulations that are compliant with all laws, including those passed by the voters and the legislature legalizing the recreational use of marijuana in the Commonwealth,” the commission said today.

Eight states and the District of Columbia have legalized marijuana for recreational use, including California, where legal sales began on Jan. 1 and are projected to bring in $1 billion annually in tax revenue within several years.

In Massachusetts, state Revenue Commissioner Christopher Harding told lawmakers last month that his department estimates it will collect $44 million to $82 million in taxes when marijuana sales are allowed to begin July 1, the start of the next fiscal year.

The state effectively taxes non-medical marijuana at 17 percent, while cities and towns can tack on an additional 3 percent.

Other analysts project the state could see as much as $240 million in tax revenue by 2021.
