Massachusetts Gov. Charlie Baker and Boston Mayor Martin Walsh are helping kick off a campaign to oppose a proposed ballot question seeking to legalize small amounts of recreational marijuana.
The Campaign For a Safe and Healthy Massachusetts will host the event Friday at the William J. Ostiguy Recovery High School in Boston.
In addition to Baker and Walsh, House Speaker Robert DeLeo, Lt. Gov. Karen Polito, Suffolk Sheriff Steve Tompkins and others will outline the reasons they oppose the question, which appears headed for the November ballot.
The question would allow people 21 or older to possess up to one ounce of marijuana for recreational use. It also would impose a 3.75 percent excise tax on retail marijuana sales, on top of the state's 6.25 percent sales tax.
