On November 8, 2016, Massachusetts voters approved Question 4 to legalize, tax, and regulate marijuana similarly to alcohol. The law took effect on December 15, 2016. In 2017, lawmakers proposed substantially changing the law. The legislature ultimately passed, and Gov. Charlie Baker signed, a compromise bill that largely respects the will of the voters.
Here is a summary of the law, as amended.
