The possession or use of ALL types of fireworks is illegal in Massachusetts - this includes common sparklers and firecrackers. Numerous injuries and fires occur every year in the Commonwealth due to the use of illegal fireworks.
To enjoy fireworks, attend one of the professional displays being held in many local communities. You can enjoy the Amherst Independance day celebration, including fireworks, on Saturday, July 1st, from 5pm to 10pm, on the south side of the UMass Alumni Stadium (rain date Saturday, July 8th).
