A new group is rising in opposition to a proposal to legalize marijuana for recreational use for adults in Maine.

The Sun Journal reports that the group Mainers Protecting Our Youth and Communities includes parents, health experts, clergy and police.

Spokesman Scott Gagnon says Mainers need to know that marijuana is often six to 10 times more potent that pot from yesteryears, and that it could be sold in gummy bears, cookies and other products targeting youngsters.

David Boyer from the Campaign to Regulate Marijuana Like Alcohol said current law already prohibits the sale of marijuana to minors, and that wouldn't change if the referendum is approved in November.

Voters in four other states, including Colorado, Oregon, Washington and Alaska, have made recreational marijuana legal. (AP)
