Colorado Gov. Jared Polis signed a bill Friday that makes Colorado the 18th state to ban gay conversion therapy for minors.
Polis, who is the first openly gay man to be elected governor in the U.S., signed the bill into law the day before the start of LGBTQ pride month. He told NBC News that he was excited to begin pride month with the ban in place.
The law prohibits psychiatrists and other mental health professionals in Colorado from engaging in conversion therapy to change a minor's sexual orientation or gender identity. Providers who disregard the ban will be subject to disciplinary measures.
Polis said in a tweet: "Colorado has joined a growing list of states that have banned so-called conversion therapy. It's a tortuous practice that has long been widely-discredited by medical and mental health professionals."
Just two days prior, Maine Gov. Janet Mills signed a similar measure banning gay conversion therapy for minors in the state.
