Close to 10 million young people in the US meet the criteria for a substance use disorder (SUD) [1]. Among adults with an SUD, more than 90% started using substances when they were young [2].
Young people face high risks of developing an addiction because they often experience social pressure to experiment with drugs. They may not yet have coping skills to manage stress and difficult emotions without the use of substances. Additionally, they may not have the awareness to recognize when casual use transitions into dependency and what help is available to them.
Addiction in your 20s not only jeopardizes health and youth, it can have lifelong ripple effects that impact employment, financial status, relationships, and mental health. Let’s take a look.
Why Young Adults Have a Higher Risk of Addiction
Brain development plays a big role in young adults’ risk of addiction. Throughout your 20s the prefrontal cortex — the brain region responsible for impulse control and decision-making — continues to mature.
On top of that, neuroimages show the brain network keeps changing throughout the 20s, and so how different areas connect and communicate isn’t yet stable.
There’s a common misconception that the brain is fully developed by age 25, but the reality is that even after major development phases, neuroplasticity fuels learning and adaptation in the brain well beyond age 25 [3].
In terms of addiction, the active brain development that takes place during the 20s means emotional centers respond to high-intensity rewards such as addictive substances. In short, the brain reacts strongly to dopamine, which makes risky and novel behavior more likely.
Another factor involved in the higher risk of addiction for young adults is environmental. Social groups, college settings, and navigating life independence can make addictive substances more accessible and encourage more experimentation. The access can also cause people in their 20s to self-medicate if they feel overwhelmed, anxious, or are confronting new or past trauma.
Addiction Triggers Among People in Their 20s
Events or emotional states that may facilitate substance use among people in their 20s are diverse. The 20s is typically a transitional and busy time, with many people trying to understand who they are and make decisions that could shape the rest of their lives.
Common occurrences that can push young adults into addictive behaviors include:
- Attending/graduating college
- Entering the workforce
- Financial strain
- Social pressure to “fit in”
- Having a mental health disorder
- Self-medication
- Loneliness
- Identity exploration
- Boredom
- Unresolved childhood trauma
Studies show long-term prescription medication use, poor relationships with parents, and parents’ education level can also contribute to the risk of having an addiction at this age [4].
The Long-Term Effects
Young adults may recreationally try substances believing they are resilient to addiction. While they may be able to abstain in the short-term, research suggests people who use substances from a young age are more likely to develop an SUD later on [5].
There are equally serious implications elsewhere for young adults who have an SUD. They are more likely to struggle at school, to have worse mental health, to be involved in a crime, to contract a sexually transmitted infection, and to have poor family planning [6]. Unintentional injury, suicide, and increased levels of violence are tied to substance use in this age group too [1].
From a financial perspective, addiction can stunt financial stability for young adults, who are at a critical stage to build long-term wealth. Buying substances, missing work, or being unable to find employment due to addiction means people in their 20s can’t achieve key economic milestones and are at risk of accumulating debt.
Substance Use Disorder Treatment for Young Adults
An SUD does not define anyone who is in their 20s or who is older. However, the earlier a person receives treatment for an SUD, the better the recovery outcomes are [7].
Structured care can help a young adult safely withdraw from substances, manage cravings, find stability, and work through the deeper drivers of addiction. Specifically, evidence-based therapies such as Family Based Therapy, Cognitive Behavioral Therapy (CBT), and Multicomponent Psychosocial Therapy have been shown to benefit young people in recovery [8].
More than simply heal the symptoms of addiction, treatment can help young adults with essential life skills, including emotional regulation, distress tolerance, and healthy relationship building. It can also introduce them to peers who are in similar circumstances, providing them with a community of support and a sense of connectedness that promotes lasting sobriety.
The levels of treatment are medical detox, residential treatment, and outpatient programs. Each level offers a different intensity of care, under different structures (e.g., staying overnight at a center or returning home after sessions), and should align with what the person needs at the time. Outpatient programs are popular with people in their 20s because young adults can study or work, maintain their independence, and still be close to personal support networks while receiving high-quality care.
Addiction Treatment at Trinity Wellness Group, Massachusetts
We understand that addiction can be slow and silent. Just acknowledging that use has gotten out of hand is a huge step.
It’s never too late to seek help. At our center in Milton, we offer tailored addiction care, run by a team of licensed specialists. Our full and half-day outpatient programs are suitable for anyone who is stable enough to live at home, but who still requires intense support.
We integrate evidence-based therapies in our programs, medication-assisted treatment (MAT) where clinically needed, and a range of holistic activities. We take a trauma-informed approach, making sure that we treat addiction symptoms but also look at the driving forces and unprocessed trauma that often lie underneath addiction.
We’re empathetic, and we work at a pace that suits each person’s needs.
