The bill (now on its way to a full House vote), if passed, would grant N.H. residents the right to possess and purchase cannabis for medical purposes, or to grow their own (up to 3 plants, in a space no larger than 50 ft). It would also allow patients from out of state to possess cannabis, though no more than 2 ounces.
The New Hampshire legislature has passed 3 medical cannabis bills previously, only to have them vetoed by the former governor. Newly appointed Gov. Maggie Hassan has publicly stated she would support a medical marijuana bill, which bodes well for HB 573, should it make it to her office to be signed into law.
If you live in New Hampshire, now is the time to contact your legislators to encourage them to support this bill. You can look up your representatives here.
