Gov. Phil Scott has signed Vermont's marijuana legalization bill into law. A Scott administration official tells WCAX the governor signed the bill shortly before 2 p.m. Monday. Scott is now the first governor in the country to sign marijuana legalization into law. Eight other states legalized marijuana through public referendums. In a letter to lawmakers, Scott said he signed the bill, H.511, with "mixed emotions." The bill allows Vermonters over the age of 21 to have an ounce of weed and to grow a few plants. Once signed, the new law goes into effect July 1.
