Beyond the Substance: Understanding What Drives Addiction
“One of the hardest things was learning that I was worth recovery.” – Demi Lovato
When we talk about addiction, we often organize the conversation around a particular substance: alcohol, opioids, cannabis, stimulants, nicotine, or another drug. These distinctions are important because different substances carry different medical risks, withdrawal patterns, and treatment considerations. Yet focusing exclusively on the substance can sometimes cause us to overlook something deeper. Many people who struggle with addiction do not remain attached to only one substance throughout their lives. The substance may change, the circumstances may change, and even the desired effect may change, while an underlying vulnerability to compulsive use remains. This raises an important question: What if understanding addiction requires us to look not only at what someone is using, but at what the substance is doing for them?
Addiction has impacted so many of us, whether directly or indirectly. I’ve had a few people very close to me whose lives were impacted by addiction. One of them was a very close friend who I grew up with in the same neighborhood during my teens. (Interestingly, we realized that our paths had crossed long before we became friends… we had played on some of the same soccer teams as children without ever really knowing each other). He was like my brother. He had a big heart, although he often filtered it through being a smartass. He was charming, athletic, funny, and naturally likable. During our sophomore year of high school, his family moved a couple towns away, where he found himself in a new social environment. With a new group of teenage friends, he began experimenting with marijuana, alcohol, and other drugs. His friends experimented too, but eventually they reached a point where they stopped, drew their lines, and moved forward with their lives. I knew many of those friends and became acquainted with them as well. But his path was different. His line kept moving further. What began as experimentation continued to escalate, eventually leading to heroin, and with it came missing classes, difficulty holding a job, stealing from his family, benders, repeated stays in rehab, and remorse.
In our early 20s, there were times when he knew exactly what was happening and genuinely wanted something different for himself. I remember deep conversations where he would tell me he wanted to be done and wanted to go to rehab. But there always seemed to be one last drug dealer to pay back, one last situation to get out of. There were nights I went with him into rough neighborhoods and random motels because I thought we were going to get him out of whatever situation he was in, and then things would finally change. But somehow, it would reel him back in. While others who had experimented alongside him had been able to walk away much sooner, he struggled to. What made his relationship with substances different?
The human brain is remarkably good at learning what provides pleasure and what provides relief. If an experience repeatedly reduces anxiety, creates energy, quiets intrusive thoughts, numbs emotional pain, or produces a sense of connection, the brain begins to remember it. Over time, stress, loneliness, conflict, boredom, certain environments, or even particular emotions can become associated with the expectation of relief. Eventually, the urge may arise before a person has consciously decided what to do. This helps explain why addiction can feel so contradictory. Someone can fully understand the consequences of using and genuinely want to stop while simultaneously experiencing an intense drive to continue. Reward pathways, stress responses, memory, emotional regulation, habit formation, and executive functioning can all become part of the cycle.
This perspective also invites a different kind of clinical curiosity. Instead of asking only, “How do we stop this behavior?” we can also ask, “What need has this behavior been attempting to meet?” For one person, alcohol may quiet social anxiety. For another, stimulants may temporarily create the energy or confidence they feel they lack. Cannabis may provide distance from racing thoughts, while opioids may offer temporary escape from emotional or physical pain. Sometimes substance use develops alongside trauma, depression, anxiety, ADHD, chronic stress, loneliness, or other difficulties. Other times there is no single explanation. Human behavior rarely fits into one simple narrative. Understanding the function of substance use does not excuse its consequences; it helps reveal where meaningful change might begin.
This becomes particularly important when multiple substances are involved. Treating each substance as an entirely separate problem can miss the shared processes underneath them. A person may stop using one drug only to find another behavior taking its place because the underlying need for relief, stimulation, escape, or reward remains unchanged. Sustainable recovery therefore may require more than removing access to a substance. It may involve learning to recognize internal triggers, tolerate uncomfortable emotions, regulate stress, develop healthier sources of reward, strengthen relationships, improve sleep and physical health, address underlying psychiatric symptoms, and create greater meaning and structure in everyday life.
Seen this way, recovery is not simply the process of becoming better at saying no. It is also the process of becoming increasingly aware of what happens within us before we feel compelled to say yes. That awareness can create a small but meaningful space between an uncomfortable internal experience and the habitual response to escape it. With time, support, and appropriate treatment, that space can grow. The goal is not merely to remove something from a person's life, but to help build a life in which the substance gradually has less of a job to perform.
