Massachusetts AG Campbell Condemns Supreme Court’s Decision Against Colorado’s Conversion ‘Therapy’ Ban For Minors

Massachusetts Attorney General Andrea Joy Campbell today issued the following statement after the Supreme Court of the United States ruled in favor of a challenge to a Colorado state law that prohibits licensed health professionals from practicing conversion “therapy” – a harmful and ineffective practice that attempts to change a person’s sexual orientation or gender identity – on minors.  

“Today’s decision not only undermines efforts to protect LGBTQ+ youth, but also disregards years of scientific research showing that conversion therapy can have a devastating impact on the mental, emotional, and physical health of young people,” said AG Campbell. “ We are reviewing the Court’s decision, and I will continue using every tool available to stand firmly against any attempt to legitimize practices that put our young people at risk.” 

In August 2025, AG Campbell joined a coalition of 21 attorneys general in filing an amicus brief at the U.S. Supreme Court in Chiles v. Salazar, supporting Colorado’s ban on conversion therapy – a practice that is not a safe or effective treatment for any condition, puts youth at risk of serious harms including increased risk of suicide, and falls below the standard of care for mental health practitioners.  

Massachusetts is one of more than 25 states that bans or restricts conversion therapy. The effect of this decision is to send the case back down to the lower court to make a determination regarding the future of Colorado’s law. This case doesn’t change the laws of any other state, including Massachusetts.
