Arizona could be one of several states to have legalization of marijuana for recreational use on the ballot in November.

The Campaign to Regulate Marijuana Like Alcohol learned Wednesday that it submitted enough signatures to be on the ballot, and the Arizona secretary of state is expected to certify the petition on Thursday, the Arizona Republic reported.

The effort faces a challenge from opponents who are suing to keep the initiative off the ballot, saying that proponents misled the public in pitching it. A hearing on the lawsuit is scheduled for Friday.

Arizona would be among a number of states that will have some form of marijuana legalization on the ballot, including California, Nevada, Maine, and Massachusetts.

In all, 25 states have legalized in some form the use of marijuana. It is legal for recreational use in Alaska, Colorado, Oregon, Washington, and the District of Columbia.
