Substance abuse and addiction can occur with drugs or alcohol, and to anyone who uses either of these. While not everyone who drinks or uses drugs will form an addiction or abuse the substances, those who do often share similarities. Multiple factors can add to one’s risk of forming an addiction to drugs or alcohol.
Early Drug and Alcohol Use as a Risk Factor
Experimenting with drugs or alcohol at an early age—particularly during adolescence—can increase the likelihood of developing a substance use disorder later in life. The brain is still developing well into the mid-20s, especially the areas responsible for decision-making and impulse control. When substances are introduced during this time, it can interfere with these developmental processes, leading to a higher risk of dependency. While early use doesn’t guarantee addiction, it is a significant contributing factor and should be addressed when considering prevention and treatment approaches.
One’s Environment Plays a Large Role
Our environment deeply influences how we respond to stress, relationships, and even how we view substance use. Growing up in a home where drug or alcohol use is common—or where emotional support is lacking—can normalize these behaviors and increase the chance of someone turning to substances as a coping mechanism. This is especially true for children and teens, who are more impressionable and may not have the tools to process trauma or emotional pain in healthy ways. Experiences like domestic conflict, neglect, bullying, or exposure to violence can all become contributing factors that set the stage for future substance abuse.
Loved ones consuming various substances as a normal occurrence can heavily sway an individual’s opinion on drugs or alcohol. It’s easy to have little to no concern about abusing a substance if someone you respect or love is doing the same. Adolescents are especially susceptible to this, along with peer pressure from friends or social groups.
Creating a positive and supportive environment is extremely beneficial for both adult and child family members. Trauma is another factor that can lead to substance abuse when left untreated. Situations that remind an individual of the trauma can become a trigger to drink or use drugs. Typically, to avoid the negative feelings and thoughts associated with said trauma.
Genetics Also Determine the Likelihood of Substance Abuse
Genetics play a significant role in one’s predisposition for addiction and substance abuse. Certain substances increase the risk of passing down a substance use disorder, with the chances ranging from 30% to 70%. Learning about family members who struggle with substance abuse or addiction can alert an individual to their possible chances.
The reason addictive behaviors can be passed down through genetics isn’t due to an individual gene, but instead various groups of genes found only in those who have issues with addiction or substance abuse. These genes change the way substances interact with the brain, making it more desirable to chase whatever influence is felt with drugs or alcohol.
It may also lead some to attempt self-medicating with alcohol or illicit drugs. Imagine a situation where a child witnesses their parents abusing alcohol to cope with stress. Not only are they seeing it as a normal practice in their environment, but they likely inherited more addictive tendencies from their parents as well.
How Chronic Stress and Life Pressures Contribute to Substance Abuse
Stress is a normal part of life, but when it becomes chronic or overwhelming, it can push individuals toward unhealthy coping mechanisms. Whether the stress comes from financial difficulties, work burnout, relationship struggles, or unresolved trauma, some individuals turn to drugs or alcohol for relief. Unfortunately, this pattern can become cyclical—substance use may temporarily numb the discomfort, but over time, it creates new problems that add more stress. Recognizing stress as a risk factor allows treatment providers to address both the root causes and the symptoms of addiction with compassionate, holistic care.
Mental Health Disorders Also Have a Strong Link to Substance Abuse
The comorbidity between addiction and mental health issues can be observed happening in both directions. Those diagnosed with a substance use disorder often develop other mental health issues during the period of substance abuse. On the other side are those with a mental health issue who turned to substance abuse for coping or self-medicating.
Nearly half of those diagnosed with a mental health issue also faced substance abuse later on in life. Overall, over 9.5 million Americans are struggling with comorbid substance abuse and mental health disorders. Genetics and environment have a large influence on both types of disorder, contributing to the high rate of comorbid disorders.
On top of this, substance abuse and mental health issues involve similar parts of the brain. Dopamine receptors and the areas of the brain responsible for our internal reward system are two of the most impactful processes. When these are negatively influenced, mood regulation and decision making become difficult.
What Happens if Substance Abuse Goes Untreated?
Substance abuse doesn’t just affect short-term behavior—it can cause long-lasting damage to the body and brain. Continued use of alcohol or drugs can lead to liver damage, weakened immune function, heart complications, cognitive decline, and increased risk of overdose. Psychologically, prolonged substance use may worsen existing mental health conditions or create new ones, including anxiety, depression, and paranoia. The good news is that early intervention and treatment can prevent or even reverse many of these long-term effects.
