The bill specifically prohibits anyone under 18 to undergo any efforts to change his or her sexual orientation, reports Reuters, noting that it got support from the California Psychological Association and the California Board of Behavioral Sciences.

The bill was sponsored by state Sen. Ted Lieu, who has expressed optimism other states would follow California’s lead to ban what he called a form of “quackery” that “is harmful,” reports NBC News. An assemblyman in New Jersey has said he plans to introduce similar legislation in his state.

The bill was largely opposed by Republican lawmakers who decried it as a violation of parents’ rights to raise their children as they wish. One conservative group has vowed to file suit against the measure, reports the LAT.
