As far as I know MMJ is not on the immediate horizon in Mass. I would not be surprised if it were to happen in the next few years however. It requires state reps and senators to have a passionate interest in passing MMJ laws, as their are many hurdles to overcome (public opinion, increasing size of bureaucracy). In RI we had a State Senator with terminal cancer that introduced the bill and many of his friends and supporters helped the laws get passed.

On the plus side, Massachusetts has decriminalized possession of less than 1/2 ounce marijuana. The penalty is a fine of at least $100. Local towns can also charge a fine in addition to the state fine. Cultivation though is still quite illegal for now.
