According to State House News Service, the rally will promote passage of a ballot question legalizing marijuana for medical use in Massachusetts, and hear from other speakers, including someone from Harvard Medical School.


MassCann says that Question 3 on the ballot will allow for the private growing of marijuana plants for patients, but also include penalties for marijuana use for non-medical reasons.

"In short, being sick will no longer be a crime, though being healthy and feeling a little too good will still be prosecuted to the fullest extent of the law," MassCann's website says.
