Los Angeles County evidence
Los Angeles County Addiction Treatment Statistics, 2024-25
Los Angeles County substance use treatment admissions are published every year by the county Department of Public Health, broken down by substance, age, housing, employment and level of care. The most recent report covers 60,797 admissions across 35,789 people in publicly funded programs, and the substance in second place is not the one most of the coverage is about.

Which substance sends the most Los Angeles County residents to treatment?
Alcohol, then methamphetamine, and the two together are three of every five admissions. Alcohol was the primary substance in 19,424 of 60,797 admissions in FY2024-25, 32.5 percent, and methamphetamine in 16,840, 28.1 percent.
Prescription drugs, which in this dataset are mostly prescription opioids and benzodiazepines, accounted for 10,213 admissions (17.1 percent) and heroin for 6,418 (10.7 percent). Marijuana accounted for 4,405 and cocaine for 1,942.
Fentanyl drives the overdose deaths, and the county is right to focus on it. But if the question is what people actually enter treatment for, the answer in this county is alcohol first and methamphetamine second, and methamphetamine has no approved medication, which changes what a good program looks like.
In residential programs specifically, methamphetamine is the primary substance in 45.1 percent of admissions, ahead of alcohol. In withdrawal management it is the reverse: alcohol is 60.8 percent, because alcohol is the withdrawal that most often needs a bed.
The age profile is similarly at odds with how addiction is usually pictured.
How old are people entering treatment in Los Angeles County?
Mostly in their late twenties through early forties. The largest band was 26-34, with 10,492 clients, 29.3 percent, followed closely by 35-44 at 10,282.
People aged 17 and under accounted for 1,407 clients, 3.9 percent, and people 65 and over for 1,665. Men were 65.9 percent of clients and women 33.1 percent.
The practical implication is that most people entering treatment here are adults of working age, and yet only 8,811 admissions, 14.7 percent, were people in work. That gap between age and employment is the first sign of who the public system actually serves.
Their circumstances outside treatment explain the gap.
What are the circumstances of people entering publicly funded treatment?
A large share are homeless and nearly all are on Medi-Cal. 26,792 admissions, 44.1 percent, were people experiencing homelessness, and 97.6 percent of clients whose records could be matched were Medi-Cal beneficiaries.
34,891 admissions, 58 percent, reported mental health issues, and 13,156, 21.6 percent, were involved with the criminal justice system. In residential programs the homelessness figure rises to 69.3 percent.
This is the figure that most sharply distinguishes the population entering the public system from the population most private treatment marketing addresses. The county report covers programs with a county contract; the private residential houses that dominate search results in Encino, Tarzana and Malibu mostly do not hold one and mostly do not state they accept Medi-Cal.
For anyone on Medi-Cal, the entry point is the county Substance Abuse Service Helpline rather than a private admissions line, and asking about Medi-Cal before the clinical conversation avoids a great deal of wasted effort.
Where people are placed once they call says a lot about what the system is built to do.
Which level of care do most people end up in?
Residential, then outpatient, then a methadone or buprenorphine clinic. Residential programs took 16,783 admissions, 27.6 percent; outpatient 14,299, 23.5 percent; and opioid treatment programs 9,809, 16.1 percent.
Withdrawal management, the county term for detox, accounted for 7,005 admissions, 11.5 percent, with an average residential detox stay of about a week. Residential stays averaged just under two months; opioid treatment program enrollments averaged well over a year.
Most people arriving have been here before. 16,083 admissions, 27.5 percent, were a first treatment episode, while 10,654, 18.2 percent, had five or more prior admissions. A program's answer to the question of what happens when someone comes back matters more than its brochure.
The San Fernando Valley accounted for 4,957 clients, 13.9 percent, the largest share of any region in the county. The county also licenses 455 residential facility records with 7,547 beds, and 55 percent of those licences are for six beds, which is the shape of the private market.
Together these figures describe a public system built for a population quite different from the one most treatment advertising pictures.
