California’s red flag law, which lets courts temporarily take firearms from people judged to be a danger to themselves or others, was followed by at most a small drop in suicide among the state’s handgun owners, and the numbers also fit no drop at all. That is the finding of a cohort study of roughly 172 million person-years published September 1, 2026 in JAMA Network Open, comparing the four years before the law took effect on January 1, 2016 with the six years after.
A statewide number says nothing about whether you should act tonight. If someone in your home owns firearms and is in a mental health crisis, the step with the clearest link to lower risk is physically separating that person from the guns: a friend’s locked storage, a relative’s house, or in some states a law enforcement agency or a dealer. That is a family decision you can make this week. Whether the person needs treatment, and what kind, belongs with their doctor. Policy estimates move slowly, and a funding decision going the other way has been modeled in deaths too.
Key takeaways
- Among California handgun owners, the law was tied to 4.1 fewer suicide deaths per 100,000 people in a year, but values from 9.5 fewer to 1.3 more all fit the data.
- The shift was bigger for firearm suicide (3.0 per 100,000) than for other methods (1.1 per 100,000), the pattern you would expect if removing guns were doing the work.
- A statewide null is not proof the orders fail. California issues them against a few thousand people a year among millions of handgun owners.
What the study found
The team used the Longitudinal Study of Handgun Ownership and Transfer, a database linking firearm transaction and mortality records for more than 38 million registered California voters. It compared suicide risk in 2012 to 2015 against 2016 to 2021 in owners versus nonowners, covering about 5.5 million handgun owners and 166.6 million nonowners aged 21 or older.
The headline estimate was 4.1 fewer suicide deaths per 100,000 handgun owners over a year, roughly one fewer death for every 24,000 owners. The uncertainty was wide: values from 9.5 fewer to 1.3 more all fit the data, so a benefit twice the estimate is possible, and so is nothing.
By method, firearm suicide fell 3.0 per 100,000 (range, 7.9 fewer to 1.9 more) and nonfirearm suicide 1.1 per 100,000 (range, 3.3 fewer to 1.1 more). The authors concluded the law was tied to a “modest population-level reduction in suicide risk, although a null effect cannot be ruled out.”
Dr. Kumar’s take
This result will be read as “red flag laws do not work.” It does not say that, and the authors say so themselves.
Think about the arithmetic. A court order applies to one person, and orders reach only a small share of the millions of handgun owners in the study. Ask a statewide rate to register that and it will struggle. Even if every order saved a life, the dose is too small to show up at that scale.
What the study does show is that the drop was concentrated in firearm suicide rather than other methods, which is the pattern you would expect if taking guns out of the house were the active ingredient. Method matters because the crisis is often brief and the method is often final.
What it means for you
If someone you live with owns firearms and is in crisis, do not wait for a legal process. Ask whether the guns can leave the house for a while. Out-of-home storage rules vary by state, and your local law enforcement agency or a firearms dealer can tell you what is allowed. If they must stay, locked and unloaded with ammunition separate is the fallback.
Then bring it up with a clinician, who can judge whether someone needs urgent care.
Prevention that works across a whole population is rare, and the evidence arrives slowly. One vaccine has been tied to a sharply lower dementia risk in older adults.
