At Laguna Shores Recovery in Dana Point, California, located in Orange County, we believe that understanding the facts is the first step toward providing compassionate and effective care. Questions like “What percentage of homeless people are drug addicts?” are often asked with urgency, but the answer is more complex than a single number. While substance use is more common among people experiencing homelessness than in the general population, it is not universal. Many individuals face homelessness due to a combination of factors, including high housing costs, unemployment, mental health challenges, and trauma, with substance use sometimes developing as a coping mechanism.

Looking at the data helps clarify the scope of the issue, identify gaps in treatment access, and highlight the real-world challenges that contribute to both homelessness and addiction. By understanding these patterns, we can better support individuals through evidence-based interventions, integrated care, and tailored addiction treatment programs that address both substance use and the underlying social, emotional, and economic factors that contribute to instability. In this article, we explore the latest statistics, the nuances behind the numbers, and what they reveal about how society can provide meaningful support to this vulnerable population.

Homelessness and Addiction: What’s the Connection?

Homelessness and addiction are closely linked, but the relationship is complex. Substance use does not cause homelessness in most cases; instead, factors like economic instability, lack of affordable housing, mental health challenges, and trauma often precede both homelessness and addiction.

At the same time, living without stable housing can increase the risk of developing or worsening a substance use disorder, as individuals may use drugs or alcohol to cope with stress, exposure to unsafe environments, or untreated mental health issues. Understanding this connection highlights the need for integrated solutions that address housing, healthcare, and addiction support together, rather than treating substance use in isolation.

Causes and Risk Factors of Homelessness and Substance Abuse

Homelessness and substance abuse often result from a combination of interrelated factors rather than a single cause. In Southern California, high housing costs mean that even a single crisis, such as job loss, illness, or family conflict, can push someone into homelessness. Untreated mental health conditions, including depression, anxiety, and trauma, can further destabilize daily life, making it harder to maintain employment or housing.

Substance use may develop as a coping mechanism or exacerbate existing challenges, but access to treatment is frequently limited; for example, a 2025 UCSF study found that only 7% of people with a history of regular drug use were receiving care. These overlapping pressures highlight the importance of addressing housing, mental health, and addiction together to prevent and reduce homelessness.

Homelessness usually results from multiple pressures occurring simultaneously, with substance use often interacting with other challenges rather than being the sole cause. Key drivers include:

  • Housing Costs: In Southern California, high rents and limited affordable housing mean that a single crisis, such as an injury, job loss, or family breakup, can quickly lead to homelessness.
  • Mental Health Gaps: Untreated conditions like depression, anxiety, or trauma can disrupt sleep, decision-making, and relationships, making it harder to maintain work and stable housing.
  • Limited Treatment Access: According to a 2025 UCSF study, only 7% of people with a history of regular drug use were receiving treatment, highlighting how care barriers can compound instability and prolong substance use.

Understanding these interconnected factors is essential for designing solutions that address both homelessness and substance abuse simultaneously.

What Percentage of Homeless People are Drug Addicts?

Substance use is a significant concern among individuals experiencing homelessness, though it is important to avoid assuming that all homeless people struggle with addiction. Estimates for current drug misuse typically range from 25% to 38%, depending on whether it includes recent use, heavy use, or a diagnosable substance use disorder.

According to the 2025 Annual Homeless Assessment Report (AHAR) by the U.S. Department of Housing and Urban Development (HUD), substance use is common but often intersects with other factors such as mental health challenges, economic instability, and lack of affordable housing. These findings underscore the importance of integrated approaches that address housing, mental health, and substance use together, rather than focusing solely on addiction.

What Are Southern California’s Addiction Rates Among Homeless Populations?

Southern California’s high housing costs and visible unsheltered homelessness can make drug use appear more widespread than it is, which is why questions about what percentage of homeless people are drug addicts feel urgent and personal. A 2025 UC San Francisco study found that 37% of homeless adults in California regularly used illicit drugs in the prior six months, with methamphetamine being the most common. The study also revealed that 27% of participants who began using drugs regularly became homeless shortly afterward, showing that substance use can follow housing loss rather than always precede it.

Local estimates in Los Angeles County place substance use disorders (SUD) among homeless populations between 20% and 35%, and frequent methamphetamine use is particularly prominent. Despite high levels of need, treatment access is limited: only 7% of those with regular drug use were receiving care, while about 21% wanted help but could not access it due to cost, availability, and system complexity. These gaps underscore the importance of expanding resources and support to help individuals engage in recovery.

Why Do Drug Use Patterns Look Different Within Homelessness?

Drug use patterns among people experiencing homelessness can vary widely due to a combination of environmental, social, and individual factors. Access to substances, local drug markets, personal coping strategies, mental health conditions, and peer networks all influence which drugs are used, how often, and in what combinations. For example, methamphetamine may be more common than opioids in certain urban areas, while alcohol or prescription drug misuse may dominate elsewhere.

Housing instability and exposure to trauma or stress can also shape usage patterns, as some individuals use substances to self-medicate or manage daily survival challenges. These variations highlight that addiction within homelessness is not uniform and requires tailored, context-sensitive approaches to treatment and support.

In other words, some people used substances long before losing housing. Others began after becoming homeless, often in the context of trauma exposure, sleep deprivation, and daily safety threats. Our programs for co-occurring disorders address these complex histories.

Homelessness and Mental Illness

Homelessness and mental illness are closely interconnected, with each often exacerbating the other. Studies indicate that a significant portion of people experiencing homelessness struggle with conditions such as depression, anxiety disorders, bipolar disorder, or schizophrenia. Mental health challenges can make it difficult to maintain stable housing, employment, or access to healthcare, while the stress, trauma, and instability of homelessness can worsen symptoms or trigger new mental health issues.

This cycle highlights the importance of integrated support systems that address both co-occurring mental disorders and housing needs, offering therapy, medication management, and community resources alongside stable living arrangements to support long-term recovery and well-being.

What Does Homelessness Look Like in Southern California?

Homelessness in Southern California is highly visible and varied, encompassing individuals living unsheltered on streets, in parks, or along riverbeds, as well as those in temporary shelters, transitional housing, or vehicles. Cities such as Los Angeles, San Diego, and Orange County have some of the nation’s highest concentrations of people experiencing homelessness, driven by high housing costs, limited affordable housing, and economic inequality.

The population is diverse, including single adults, families with children, youth, veterans, and older adults, each facing unique challenges. Youth may become homeless due to family conflict or aging out of care systems, while older adults often struggle with fixed incomes amid rising rents. Black, Latino, and Indigenous individuals are frequently overrepresented in local counts, reflecting systemic inequities in housing, healthcare access, and income.

Homelessness is further complicated by mental illness, substance use, and limited access to healthcare, underscoring the need for comprehensive support systems that address immediate needs while promoting long-term stability and recovery.

Are Drug Rehab Centers Fueling Homelessness in Southern California?

Drug rehab centers are not a primary cause of homelessness in Southern California, though gaps in treatment and aftercare can contribute to housing instability for some individuals. Many people enter rehab without secure housing, and upon completing treatment, a lack of affordable housing or supportive living options can leave them vulnerable to returning to the streets.

While rehab programs provide critical addiction treatment, without integrated support, such as transitional housing, case management, and access to mental health services, some clients may struggle to maintain stability. This highlights the importance of linking rehab with broader social services to ensure recovery efforts do not inadvertently coincide with homelessness.

How Laguna Shores Recovery is Promoting Recovery

Effective care for substance use and co-occurring mental health conditions works best when it is individualized and clinically structured. In a region where questions about the percentage of homeless people struggling with addiction are common, pairing population data with a clear, personalized pathway into assessment and treatment is essential.

Support at Laguna Shores Recovery begins with a thorough evaluation of substance use patterns, withdrawal risk, mental health symptoms, and safety concerns. This assessment ensures that the level of care matches each person’s medical needs and daily stability.

Comprehensive Treatment Approaches Include:

  • Medical detox: Drug and alcohol detox is the first step of the recovery process, prreparing someone for treatment. It provides clinical monitoring and symptom relief during withdrawal, with planning for the next phase of care. Alcohol and opioid withdrawal can carry higher medical risks, making supervision critical.
  • Medication-assisted treatment (MAT): For opioid use disorder, medication-assisted treatment utilizes therapy along with medications like buprenorphine to help reduce cravings and withdrawal symptoms. For alcohol use disorder, medications such as naltrexone can reduce urges depending on medical history.
  • Therapy: Addresses addiction alongside conditions like anxiety, PTSD, or depression. Behavioral therapies focus on identifying triggers, practicing grounding techniques, and rebuilding routines that support sleep, nutrition, and overall wellness.
  • Group and family support: Group therapy reduces isolation and builds practical coping skills, while family work focuses on healthy boundaries, safety planning, and supportive engagement without enabling substance use.
  • Aftercare programs and stability planning: Aftercare planning often includes follow-up therapy, ongoing recovery supports, and steps to maintain housing stability. Transitions are high-risk periods, making these supports vital.

Access to High-Quality Treatment is Available in Southern California

While statistics can help frame the public conversation, they cannot replace a professional evaluation. If you are asking what percentage of homeless people are addicted to drugs because someone in your life is struggling, a clinical assessment can clarify the severity of substance use and any co-occurring conditions.
