Massachusetts -- There is no sense to be found in the prosecution of individuals for possession of small amounts of marijuana. It clogs up our overburdened criminal-justice system, while achieving absolutely nothing. It also unnecessarily infringes on the civil liberties of those having a harmless toke, and provides a too-easy avenue for law-enforcement personnel to affix a criminal history to an undeserving citizen often a young person who merely looks like trouble to a cop.
