In a recent discussion about homelessness, someone stated that most homelessness was caused by drug and alcohol abuse. That seemed obviously false to me, so I did some cursory research with AI and Wikipedia.
AI states, “Homelessness in America is primarily driven by a severe shortage of affordable housing and high housing costs relative to stagnant wages.”
- Weakened Safety Nets: The expiration of federal COVID-19 relief funds, combined with limited rental assistance and underfunded public benefits, removed critical buffers for low-income households. [1]
- Restrictive Zoning Laws: Outdated local zoning rules, land speculation, and high construction costs make it difficult to build enough low-cost housing in high-demand or coastal cities. [1, 2]
Contributing Life Events and Vulnerabilities
- Systemic and Institutional Gaps: Individuals leaving foster care, the criminal justice system, or the military frequently face immediate housing barriers and lack supportive transition networks. [1]
Wikipedia entry on homelessness agrees with the above but provides a more complete list. It cites the causes of homelessness as 1) Rent and eviction; 2) Economics [lack of jobs that pay living wages, lack of affordable housing]; 3) Physical and mental health; 4) Discrimination; 5) Human and Natural Disasters; 6) War; 7) Foster Care; 8) Choice; and 9) Childhood Predictors [events that can occur in childhood, which are common experiences among many who experience homelessness.]
The relationship between drug abuse and homelessness
1. Substance Abuse as a Consequence, Not a Cause
For many individuals, drug or alcohol use begins after they become homeless. The extreme stress, trauma, physical pain, and sleep deprivation of living on the street lead many people to use substances as a coping mechanism or a way to self-medicate.
2. An Accelerator of Housing Instability
In areas where housing is highly affordable, people with substance use disorders are rarely homeless because they can still maintain a place to live. However, in expensive housing markets, a drug addiction can quickly lead to job loss, depleted savings, and severed relationships with family or friends who might otherwise provide a safety net, ultimately triggering homelessness.
3. A Barrier to Re-Housing
Once someone is homeless, active substance abuse makes it incredibly difficult to navigate the complex social services system, secure employment, or meet the strict behavioral requirements of traditional homeless shelters.
By the Numbers – According to data compiled by the National Coalition for the Homeless and the Substance Abuse and Mental Health Services Administration (SAMHSA):
- Roughly 25% to 35% of the unhoused population in the U.S. experiences chronic substance use disorders.
- By comparison, the vast majority of people experiencing homelessness do not struggle with drug abuse, highlighting that structural factors like poverty and high rent are the true primary drivers.
So that is the answer to the question. Homelessness is not primarily caused by drug abuse. Of course, you could deny the Wikipedia and AI claims, which link to the best research on the topic. But if you won’t recognize some impartial umpire to adjudicate our disputes, then we have reached an impasse. You can’t have fruitful dialogue with people who only accept sources that agree with them. (They are like politicians who only accept elections they win as legitimate.)
We might also note that some countries—Finland, Norway, Japan—have virtually eliminated homelessness. According to AI, the common denominator among the countries that have nearly solved homelessness is that “they look at housing as healthcare infrastructure.” Studies of Finland‘s program revealed that providing a home first actually saves the government between €9,600 and €15,000 per person annually by drastically reducing emergency room visits, policing, and court costs. [1, 2, 3, 4]
However, I will admit that I’m doing nothing to help the homeless in my city besides giving a few dollars to panhandlers. Whether that helps or not is an open question. So while sympathetic to their plight, I’m merely engaging in what the Dalai Lama calls “sloppy sympathy.”
