Last month the Massachusetts Department of Health announced the first 20 medical marijuana dispensaries to receive licenses. Now, the head of the state’s medical pot program has announced that all licensed dispensaries are expected to offer home delivery services.

Karen van Unen, director of the Massachusetts medical marijuana program, said, “We really wanted to ensure that patients had choice.” Additionally, van Unen confirmed that dispensaries are expected to begin providing medicine by the summer.

Officials expect approximately 120,000 pot patients during the first two years of the state’s program.

Few states allow home delivery of medical marijuana – Massachusetts joins legal medical pot delivery states Rhode Island, New Mexico and California.
