Missouri voters decide Amendment 3 tomorrow. Parents should know what it does for their children: Amendment 3 would write Missouri's ban on gender-transition procedures for minors into the state Constitution.
That matters because part of the current ban is temporary. Under Missouri's SAFE Act, the prohibition on prescribing cross-sex hormones and puberty blockers to minors "shall expire on August 28, 2027."
What Missouri Law Does Today
Section 191.1720 of Missouri law bars health care providers from prescribing or administering cross-sex hormones or puberty-blocking drugs to minors for the purpose of gender transition.
That protection is in force today. The same law sets the date it ends.
Since the SAFE Act took effect in 2023, Missouri children have been shielded from drugs that alter the course of puberty during the years when a child's body and mind are still forming. Families have been able to count on that line holding while their children grow up.
The Protection Has a Deadline
On August 28, 2027, unless legislators act again, the ban on hormones and blockers simply ends.
Puberty blockers and cross-sex hormones act on a child's body during the years it is still developing. Leaving them on a timer means the protection families rely on most could disappear on a date already printed in state law. Renewal would depend on a future legislature acting under pressure that no parent can predict.
A deadline also tells activist groups and national medical organizations exactly when to focus their lobbying, because the date is written into the statute for anyone to read. A family raising a struggling teenager would be left wondering whether the safeguard protecting their child this year will still be on the books next year.
What Amendment 3 Would Change
The amendment's text states that "no cross-sex hormones or puberty-blocking drugs shall be knowingly prescribed or administered for the purpose of gender transition to children under eighteen years of age." It also prohibits gender-transition surgeries on children under 18. Care for children with medically verifiable disorders of sex development, and treatment for conditions unrelated to transition, remains available.
Constitutional text has no expiration date. Changing it would require Missourians to vote again.
That moves the decision out of a statute that can lapse and into a standard that belongs to the voters themselves. No future session could quietly let the protection run out, and no deadline could be used as leverage to weaken it. Missourians would set the rule, and only Missourians could undo it.
Permanence Protects Children
A child who is eleven today will be fifteen when the drug ban is scheduled to expire. Her protection should not depend on the calendar. A constitutional standard tells hospitals and clinics that Missouri's answer is settled, and it keeps that answer in place for every child growing up here.
Children who are struggling with their sense of self deserve patience, counseling, and the support of their parents while they grow. Drugs that halt or redirect puberty take that time away. Missouri decided in 2023 that its children should have it, and Amendment 3 lets voters make that decision permanent.
Tomorrow, Missouri voters can close the gap the 2027 deadline leaves open. A yes vote on Amendment 3 turns a temporary law into a lasting commitment to Missouri's children. Polls are open from 6 a.m. to 7 p.m.
