The Vermont Senate Committee on Judiciary approved a bill (4-1) on Friday that would end marijuana prohibition in the state and regulate marijuana for adult use.

S. 241 would make it legal for adults 21 years of age and older to possess up to one ounce of marijuana and establish a tightly controlled system of licensed marijuana cultivation sites, testing facilities, and retail stores. It would also create a study commission to examine issues such as edible marijuana products and home cultivation, which would not be allowed under the bill. It would remain illegal to consume marijuana in public or drive under the influence of marijuana. If approved, the new law would not take effect until January 2018.

Earlier this week, Gov. Peter Shumlin and Senate Judiciary Chairman Dick Sears announced they would support a bill that “cautiously and deliberately” ends marijuana prohibition in Vermont.

A strong majority of Vermonters (56%) support regulating the cultivation and sale of marijuana for adult use, according to a statewide survey conducted by the Castleton Polling Institute in September.
