Young people struggling with youth drug treatment needs have long been underserved by a system built around adults. That is now changing. The American Society of Addiction Medicine (ASAM) has published a landmark framework dedicated entirely to substance use disorder care for adolescents and young adults under 25, separating their standards from adult guidance for the first time.
The new volume, titled the Adolescent and Transition-Aged Youth edition of The ASAM Criteria, sets out the full range of services that should be available to every young patient. Previously, adolescent addiction treatment standards sat buried within adult-focused criteria, a setup that many clinicians had criticised for years.
Brain development continues well into a person’s mid-twenties. That biological reality shapes the entire framework. Young people are not simply smaller adults, and the risks they face from substance use reflect that difference.
Why Youth Drug Treatment Needs Its Own Framework
The numbers make a sobering case. Around 80% of adults living with substance use disorder started using substances before the age of 18. Those who begin before 15 are 6.5 times more likely to develop a dependency than those who wait until 21 or older. Early exposure does not just raise risk. It can reshape development, delay the acquisition of life skills, and set a difficult course for decades to come.
“Ongoing brain development during these formative years puts youth at a greater risk of developing the disease of addiction, which can lead to poor health outcomes and delayed life skill development,” said Dr Corey Waller, editor-in-chief of the new volume.
The ASAM now recommends early intervention for any young person already using substances and showing signs of rapid escalation. Waiting for a formal diagnosis before acting is no longer the preferred approach.
Adolescent Addiction Treatment: A Holistic, Family-Centred Model
The updated standards place the young person firmly at the centre, but they also widen the lens considerably. The framework promotes a model that brings in mental health services, connects with schools and community networks, and treats prevention as seriously as treatment itself.
This matters because youth drug treatment challenges rarely travel alone. Most adolescents dealing with substance-related difficulties also carry co-occurring mental health conditions. The new guidance pushes clinicians to address both at the same time, not in sequence.
The continuum of care expands too. New service levels include ongoing remission monitoring and integrated withdrawal management within youth-specific programmes. These are areas that existing guidance had largely overlooked.
Rising Risks Make the Case for Change
The clinical picture for young people has grown more complex in recent years. Fentanyl and other high-potency substances now reach adolescents far more readily than before. Clinicians report encountering levels of risk in young patients that would have been uncommon a decade ago.
“While there will be challenges to overcome to make this vision a reality, we must commit to building systems and payment models capable of delivering effective interventions and treatments for all young people who need them,” said Dr Waller.
Putting the New Standards Into Practice
ASAM presented the new criteria on 25 March at the Joint Meeting on Youth Prevention, Treatment, and Recovery. The Hazelden Betty Ford Foundation published the complete volume online and will release a print edition in June.
The Foundation also built a digital interface to help clinicians across the full care team put adolescent addiction treatment into practice without friction.
“The ASAM Criteria’s new adolescent treatment standards represent a tremendous opportunity to further elevate and individualise care for our nation’s children and young adults,” said Dr Joseph Lee, president and chief executive of the Hazelden Betty Ford Foundation.
The framework asks more than clinicians to act. It calls on commissioners, policymakers and system leaders to fund and build the infrastructure these standards require. With the evidence pointing clearly to adolescence as the window where intervention matters most, getting that infrastructure right carries consequences that stretch well beyond the clinic.

The choices you make in your twenties may feel a world away from who you will be at 65. But a landmark new study from the University of Michigan suggests the brain keeps a much longer record than most of us realise. Researchers found that young adult substance use, including binge drinking, frequent cannabis use, and daily cigarette smoking between the ages of 18 and 30, links significantly to poorer self-reported memory in midlife, between the ages of 50 and 65.
The findings appear in the Journal of Aging and Health. The National Institute on Drug Abuse funded the work, making it one of the first studies to track these patterns across multiple decades of a person’s life.
A Study Decades in the Making
The research drew on data from the Monitoring the Future Longitudinal Panel Study. It followed participants from age 18, as far back as 1976, through to their mid-sixties. This long view let researchers see not just what people did in their youth, but what those habits ultimately cost them.
“Substance use has both acute and long-term effects on health and well-being,” said Megan Patrick, research professor at the Institute for Social Research. “Poor memory is a common sign of early dementia. We examined whether young adult substance use links to poor memory decades later in midlife.”
The study spanned nearly five decades. It captured real behavioural patterns across generations of young Americans, giving its conclusions real weight.
How Young Adult Substance Use Damages the Brain: Two Different Pathways
Not all substances damage the brain in the same way. The team identified a “triple threat”: binge drinking, near-daily cannabis use, and daily cigarette smoking in young adulthood. All three connect to memory problems in later life, but through entirely different mechanisms.
Cigarettes: the direct threat
Daily smoking between 18 and 30 predicted poorer memory in early midlife. Crucially, this held true even for people who stopped smoking by age 35. Quitting later in life does not appear to undo what cigarettes do to the developing brain during young adulthood.
Young brains are still forming during this period. Cigarette toxins appear to leave a mark that persists for decades, regardless of what happens afterwards.
Alcohol and cannabis: the addiction route
For binge drinking and frequent cannabis use, the picture differs. Heavy substance use in young adulthood does not directly cause memory loss thirty years later. Instead, it raises the likelihood of developing a Substance Use Disorder (SUD) in the thirties. That ongoing disorder then drives poorer cognitive functioning later in life.
This distinction matters enormously. For alcohol and cannabis, the window for intervention does not close at 30. Treating a substance use disorder in midlife could still help protect the brain.
“Even if someone thinks their current substance use may not be problematic because they don’t see it as affecting their health right now, there are still potential longer-term consequences to consider,” Patrick said.
What the Numbers Say About Heavy Substance Use in Young Adulthood
Self-reported poor memory is an early marker of cognitive decline and, in some cases, an early sign of dementia. Dementia now affects an estimated 55 million people worldwide, according to the World Health Organisation. That figure could reach 139 million by 2050, making early-life risk factors a pressing public health concern.
The study found that all three forms of heavy substance use in young adulthood directly associated with higher odds of poor self-rated memory in late midlife. For alcohol and cannabis, substance use disorder symptoms in early midlife fully explained those associations. For pack-a-day or heavier cigarette smoking, no such explanation applied, pointing to direct neurological damage instead.
Why Young Adult Substance Use Puts the Developing Brain at Risk
The brain does not finish developing until the mid-twenties. The prefrontal cortex, the region that handles decision-making, emotional regulation, and memory formation, is among the last areas to mature. Young adulthood is therefore a period of heightened neurological sensitivity.
“Young adulthood is a critical period for brain development,” Patrick noted. “Substance use patterns established during this period may have lasting consequences on memory and cognitive health much later in life.”
Heavy substance use in young adulthood is not simply a lifestyle choice with short-term effects. The evidence suggests it may reshape the trajectory of cognitive ageing for decades.
What This Means If You Smoked or Drank Heavily in Your Twenties
For those who smoked daily in their youth and have since quit, the findings may feel alarming. Giving up cigarettes by 35 does not appear to cancel the earlier neurological impact. Even so, cognitive decline is not inevitable. Staying proactive about brain health matters more than ever: regular exercise, good sleep, mental stimulation, and avoiding further substance use all help.
For those who drank heavily or used cannabis often in their twenties, the outlook is more actionable. Memory decline in this group links to ongoing substance use disorders rather than past behaviour alone. Getting appropriate support and treatment in midlife remains a meaningful step worth taking.
“Understanding these risk factors and their trajectory across the lifespan will inform strategies to support cognitive health,” Patrick said.
The Case for Early Intervention Against Young Adult Substance Use
Early action works far better than trying to reverse damage later. Identifying and addressing substance use in young people, before patterns become entrenched and neurological costs accumulate, gives the brain its best chance.
“This study demonstrates potential long-term detrimental impacts of young adult heavy substance use on cognitive health later in life,” Patrick said. “It highlights the importance of early interventions.”
For public health, the implications are clear. Prevention and support programmes targeting young people protect far more than immediate wellbeing. They may be among the most powerful tools available for safeguarding a generation’s long-term cognitive health.

Violence is one of the most underreported issues facing women who use drugs. A major study published in JAMA Network Open in March 2026 shed new light on how widespread and serious this problem is, and why so many women suffer in silence.
The findings are deeply concerning. Yet understanding them is an important step towards building a society that truly protects its most vulnerable members.
What the Research Found About Violence Against Women Who Use Drugs
The study followed 431 women in Melbourne, Australia, over more than a decade. Researchers combined survey responses with hospital, ambulance, and emergency department records. The results paint a stark picture.
By the end of the study period, 82% of women had experienced at least one assault. A further 38% had experienced at least one sexual assault. These rates are roughly double those in the general female population, where around 39% report lifetime violence and 22% report sexual violence.
Almost one in four women (23%) attended an emergency department because of assault. One in five (19%) ended up in hospital. Ambulance callouts for assault reached 17% of the cohort.
Violence was not only common but recurring. At follow-up interviews, 59% of women reported being assaulted since their last interview, roughly within the previous 12 months. The median number of lifetime assaults was five, though many women reported far higher numbers.
Who Was Carrying Out the Violence?
Perpetrators went well beyond intimate partners. Whilst 53% of women named a partner as an assailant, nearly half (43%) also reported attacks by a stranger. That proportion is considerably higher than in the wider population. Friends or other family members were named by 39% of women. Drug dealers or other people who use drugs featured for 30%.
This range of perpetrators matters. Most support services focus on domestic and family violence. When assault also comes from strangers or people connected to drug environments, the gap in available support becomes very clear.
Assault and Drug Use in Women: The Barrier of Stigma
Despite how often violence occurred, only around one in three women sought health care after an assault. That figure alone tells us something has gone seriously wrong.
Qualitative interviews with ten women revealed why so many stay silent. Stigma came up repeatedly. Women felt judged or dismissed by healthcare providers the moment staff learned about their drug use, even when that use was years in the past.
One woman in her 50s put it plainly: some doctors “don’t want to know you” once they discover a history of drug use, regardless of how long ago it was.
Retelling a complex and painful history to every new clinician is exhausting. For women carrying trauma, that prospect alone can stop them from seeking help.
Fear of Losing Children
Fear of child protection involvement stood out as one of the biggest barriers. Several women stayed silent about violence because they feared that speaking up would lead to their children being removed.
Sara described being “too scared” to reach out. She believed she would have opened up had she found someone she trusted, someone who would not immediately involve child protection services.
The numbers tell a similar story. Women with a history of child removal were more than twice as likely to seek health care after assault. Women who reported sexual assault had four times the odds of seeking help. Severity clearly pushes some women to act. But for many others, fear continues to win.
Violence Against Women Who Use Drugs: Practical Obstacles Matter Too
The barriers around assault and drug use in women are not only emotional. Practical challenges block access just as effectively.
Some women could not attend services because they had no transport. Others lacked phone credit to call helplines. Many services required a phone call just to book an appointment, an immediate obstacle for anyone without a working phone.
Eve had been in multiple abusive relationships and never once accessed support. She named transport costs and phone credit among her reasons. She also pointed out that even when a service offered a free number to ring, finding a payphone that could make the call was its own challenge.
The Difference a Trusted Clinician Can Make
The research also captured something genuinely hopeful. When women found a clinician they trusted, that relationship changed everything.
Jane described a maternal child health nurse who noticed signs of abuse across several visits. The nurse reached out consistently, and when the time came, helped Jane access refuge housing with all four of her children. Jane said the team made her feel completely safe and supported her through the whole process.
Mira credited her prescriber with helping her leave an abusive relationship. He asked about her safety at every visit and offered to document her injuries. That steady, non-judgemental concern gave her the confidence to walk away.
Individual clinicians can make an enormous difference. Relationship-based care matters deeply for this group of women.
What This Means for Policy and Prevention
The study’s authors called for women who use drugs to gain formal recognition in Australia’s National Plan to End Violence Against Women and Children. That plan currently acknowledges elevated risk for Aboriginal and Torres Strait Islander women, culturally and linguistically diverse women, LGBTQIA+ people, and women with disabilities. It does not name women who use drugs.
That gap needs addressing. Violence against women who use drugs occurs at rates that exceed even other marginalised groups already recognised in policy. Without targeted support, this population stays excluded from the systems designed to help them.
Violence and substance use are deeply connected. Services need to reflect that reality. Women-centric models, built on trust and staffed by people with relevant lived experience, offer a stronger path forward than approaches that inadvertently penalise women for their circumstances.
Conclusion
Violence is pervasive in the lives of women who use drugs, it is severe, and the systems meant to help them are missing them. Women do not stay silent because they want to. Stigma, fear, and practical barriers push them away. The research community has now documented this clearly. The next step belongs to policymakers, services, and clinicians who have the power to respond.
Recognising this burden is not just a research priority. It is a moral one.

Research shows that spirituality and drug use prevention are closely linked. Millions of people struggle with alcohol and drug use, yet spiritual engagement remains one of the least discussed protective factors in mainstream health. A landmark meta-analysis in JAMA Psychiatry (February 2026) pooled data from 55 longitudinal studies and over 540,000 participants. The results were clear: spiritual practice consistently reduces the risk of harmful substance use.
People with higher spiritual engagement showed a 13% reduction in harmful substance use across all drug categories. Those attending religious services more than once a week saw an 18% reduction.
What Does “Spirituality” Actually Mean?
An international consensus definition describes spirituality as a dynamic aspect of humanity. People use it to seek ultimate meaning, purpose, and transcendence. It also covers connection to self, family, community, nature, and the sacred.
This is a broad and inclusive definition. It covers formal religious practice, but it also reaches far beyond it. Prayer, meditation, a sense of life purpose, and connection to community all count as spiritual practice. So does seeking meaning through nature or service to others. Notably, 28% of adults in the United States now identify as religiously unaffiliated. That makes this wider framing of spiritual practice and substance use especially relevant.
Spirituality and Drug Use Prevention Across All Age Groups
Spiritual practice protects people across the full life course. Several studies in the review focused on adolescents and young adults, a group especially vulnerable to early substance use initiation.
Early initiation matters. The younger a person is at first use, the more likely they are to face chronic problems later in life. One large prospective study tracked more than 5,000 young people aged 12 to 17. Regular religious service attendance linked to a 15% drop in cigarette smoking and a 33% reduction in illicit drug use. Studies in adults showed consistent benefits too, spanning populations across Europe, Australia, Japan, South Africa, and North America.
Spirituality and drug use prevention work hand in hand at every age. That is a finding worth taking seriously.
What the Research Found
The 2026 meta-analysis is the first to formally measure the longitudinal relationship between spirituality and alcohol and other drug (AOD) use. Researchers pooled data from studies published between 2001 and 2022. The protective effect held firm across every drug category studied.
Key statistics from the research:
The overall risk reduction across all substance types reached 13% (risk ratio 0.87, 95% CI 0.84 to 0.91). Attending religious services more than once a week produced an 18% risk reduction. An estimated 60% of effects showed at least a 10% risk reduction. Virtually all 134 individual effects across the 55 studies pointed in a protective direction.
Multiple sensitivity analyses confirmed these findings. Excluding any single study did not shift the overall result. Researchers also confirmed that any unmeasured confounding factor would need to be very large to explain away the association entirely.
Why Spiritual Practice Supports Substance Use Prevention
Researchers point to several reasons why spiritual practice and substance use prevention connect so reliably.
Being part of a spiritual community gives people social belonging and support. It introduces shared norms around abstinence or moderation. It provides access to meaning and purpose, which can reduce the appeal of substances as a coping tool. People also build practical coping strategies through prayer, meditation, self-reflection, and community engagement.
Neuroscience adds another layer. Regular spiritual practices appear to influence brain regions that handle stress regulation, reward processing, and social connection. These are exactly the systems that substance use disrupts.
Social norms play a big role too. When a person belongs to a community where heavy drinking or drug use is uncommon, and where other sources of joy and connection are available, exposure to risk naturally falls. Community belonging shifts what feels normal and what feels appealing.
Spiritual Practice and Recovery: Not Just Prevention
Spiritual practice and substance use recovery show the same positive relationship. The meta-analysis examined recovery-focused studies and found a risk ratio of 0.82 for recovery outcomes. That sits close to the prevention figure of 0.87.
This aligns with the long-standing role of spirituality in mutual support programmes like Alcoholics Anonymous and other 12-step models. These programmes build recovery around spiritual concepts: connection to something greater than oneself, self-reflection, forgiveness, and community.
The cultural dimension matters here. Over half of African American adults in recovery say spirituality or faith “made all the difference” in their journey. That rate is two to three times higher than among White respondents. Effective support needs to respect those differences and meet people where they are.
What This Means in Practice
These findings carry practical weight for clinicians, communities, and families.
Clinicians can ask simple questions: “Is religion or spirituality important to you when thinking about your health?” That opens a conversation without imposing any belief system. Acknowledging spiritual practice as part of person-centred care fits both the evidence and good clinical ethics. Addiction training programmes could also expand to include this dimension.
At a community level, spirituality and drug use prevention goals align well with public health outreach. Partnerships between health bodies and faith or spiritual communities can extend reach, strengthen social connection, and create genuine alternatives to substance use. Any such work must respect individual autonomy. Participation in faith activities should always be a free choice.
People who do not identify with a religious tradition still benefit from community life and meaning-making. The mechanisms, belonging, purpose, coping, and connection, apply beyond any single tradition or worldview.
Looking Ahead
This field is still developing. Future research should explore how spiritual practice and substance use prevention interact across different substances, demographic groups, and cultural contexts. The current evidence base leans heavily on Western, predominantly Christian settings. A more globally representative body of research is needed.
Standardising spirituality measures across studies will also strengthen future findings. Randomised trials, where ethical and feasible, will help determine whether these associations are genuinely causal.
What is already clear: the relationship between spiritual practice and substance use is consistent, meaningful, and well evidenced. Treating spirituality as part of a whole-person approach to wellbeing, always with respect for individual belief and culture, is a direction that deserves serious attention.

Over half a million people. Fifty-five rigorous studies. One remarkably consistent finding. Spirituality and drug prevention are now firmly linked by science, and a landmark Harvard study has put hard numbers to it. People who engage in spiritual practices are significantly less likely to misuse alcohol, tobacco, marijuana, and other drugs. Researchers at Harvard T.H. Chan School of Public Health led the study, the first of its kind to measure this relationship across decades of global data.
The results offer real hope for families and communities affected by substance misuse worldwide.
What the Research Found on Spirituality and Drug Prevention
Researchers drew on 55 carefully selected longitudinal studies published between 2000 and 2022. Together, those studies tracked more than 540,000 participants across multiple countries. Broad spiritual engagement, including attending religious services, praying, meditating, and seeking spiritual community, cut the risk of harmful alcohol and drug use by 13%.
That figure rose to 18% among people who attended religious services at least once a week.
The protective effect held across all four drug categories: alcohol, tobacco, marijuana, and illicit drugs. Studies came from the United States, Europe, Asia, Africa, and Latin America, making this one of the most globally consistent findings in public health research to date.
“The consistency of the results across all the studies, including over a dozen studies conducted outside of the US, was striking,” said senior author Tyler VanderWeele, Professor of Epidemiology at Harvard. “All but a few showed a protective, not detrimental, effect.”
Lead author Howard Koh, Harvey V. Fineberg Professor of the Practice of Public Health Leadership, put it plainly. “For many individuals and families, using spirituality as a resource, whether that be attending religious services, meditating, praying, or seeking other forms of spiritual comfort, may be an avenue to enhance their health,” he said.
A Once-in-a-Decade Advance
Meta-analyses examining longitudinal data on spirituality and health are rare. VanderWeele called this one “a sort of once-in-a-decade advance,” and it is easy to understand why.
Earlier research hinted at the connection between faith and lower substance use. But those studies tended to examine one drug type, one population, or one country. This research pulled together the full picture. It also set a high bar for quality. To qualify for inclusion, a study had to use validated measures of spirituality, follow participants over time, and involve large enough sample sizes to draw meaningful conclusions.
The research team ran extensive sensitivity analyses to stress-test the findings. Even worst-case scenario models, which used only the studies showing the weakest protective effects, still pointed toward a meaningful reduction in risk. The evidence linking spirituality and drug prevention proved difficult to shake.
Why Spirituality Reduces Alcohol and Drug Misuse
Several mechanisms help explain why spirituality reduces alcohol and drug misuse so consistently.
Spiritual communities reinforce social norms around sobriety and moderation. They give people a sense of belonging and purpose, two things increasingly recognised as central to mental wellbeing. Faith practices such as prayer and meditation may also help regulate stress responses in the brain. Emerging neuroscience points to spiritual practices engaging regions associated with reward processing and emotional regulation.
When people have meaning, community, and healthy coping tools, they are less likely to turn to substances.
The 12-step recovery model, used by Alcoholics Anonymous and many other mutual aid programmes, rests on spiritual principles: surrender, reflection, community, and connection to a higher power. This meta-analysis reinforces that those spiritual foundations are not just background noise in recovery. They may be active ingredients. A 2020 Cochrane Review of 27 studies found that Alcoholics Anonymous and 12-step facilitation outperformed other clinical interventions, including cognitive behavioural therapy, in sustaining 12-month abstinence rates.
Spirituality and Drug Prevention Across Cultures and Demographics
One of the most striking aspects of this research is how widely spirituality and drug prevention findings apply. Studies came from Norway, Japan, Mexico, South Africa, Poland, Switzerland, Australia, Malaysia, and Thailand. The relationship between spiritual practice and lower substance misuse is not limited to Western or Christian contexts.
Spiritual engagement also appears to offer particular benefits to groups who face greater vulnerability. Among African American participants across several studies, consistent religious attendance linked to substantially lower odds of cocaine, marijuana, and cigarette use over time. Among juvenile offenders, those whose religious involvement grew over a decade-long follow-up showed greater reductions in drug use.
For young people, the timing matters. Early initiation of substance use strongly associates with more severe problems later in life. Spiritual engagement during adolescence can therefore carry compounding benefits across the life course.
What This Means for Clinicians and Communities
The study’s authors frame their findings as an opportunity, not a prescription. Spirituality is personal. No one should feel their recovery path must include religion or faith. But when spirituality already plays a role in someone’s life, the data show it is a resource worth acknowledging.
Health professionals can start by simply asking patients whether spirituality or religion matters to them and whether they would find value in discussing it. For those working in addiction treatment, understanding spirituality and drug prevention together could mean incorporating faith-grounded approaches alongside existing clinical tools.
At a community level, partnerships between public health organisations and faith communities can expand access to support services. Spiritual communities have long worked to address the root causes of substance misuse: stress, loneliness, and loss of purpose, often long before researchers began to measure the impact.
Spirituality and Drug Prevention: A New Public Health Priority
Nearly 48.5 million Americans currently meet the criteria for an alcohol or other drug disorder. Only around one in four received any treatment in the past year. The need for effective, accessible, and community-rooted prevention has never been more urgent.
This research builds a compelling evidence-based case that spirituality and drug prevention belong in the same conversation. Whether through a place of worship, a meditation practice, a 12-step group, or another form of meaning-making, spiritual engagement could be one of the most powerful and underused tools in tackling substance misuse.
