Addiction Origins: Why Moderation Can Be Challenging

It’s a Saturday night and your friends are enjoying a drink or two, laughing, and having a good time. For them, it’s just that—a good time. But for you, it’s something more. Maybe one drink leads to two, then two to four, and before you know it, you’ve lost count…again. You may be wondering, “Why can my friends drink just a few, but I can’t?” Understanding the origins of addiction may offer some answers and, ultimately, bring hope for those who want to break free.

Why Some People Can’t “Just Have One”

For some, moderation simply doesn’t exist. And no, it’s not a lack of willpower. Addiction is a complex disease of the brain with roots in genetic, environmental, and social factors. Understanding the interplay of these things can shed light on why some people are more vulnerable to addiction than others. 

Research shows that genetics play a significant role in addiction. Studies estimate that about 40-60% of addiction vulnerability is heritable. This means if addiction runs in your family, your risk of developing a substance use disorder is higher than those without addiction in their gene pool. 

When substances like alcohol enter the body, they activate the brain’s reward system, releasing dopamine - a chemical linked to pleasure and motivation. In people with a genetic predisposition to addiction, these pathways may be extra sensitive, making substances more appealing. This genetic tendency could explain why some people find it harder to stop drinking once they’ve started. Their brains are literally wired for addiction. 

The age when someone first tries alcohol or drugs can significantly impact their risk of addiction. Young adults who start drinking at an early age may be more vulnerable to developing an addiction later in life as their brains are still developing. Early exposure can change the brain’s wiring, making it more challenging to control substance use. Couple that with someone whose got a family history of addiction, and the risk amplifies.

While genes set the stage, a person’s environment can be a big reason for how addiction develops. If you grew up in a family or community where heavy drinking or drug use was normalized or used as a regular coping mechanism, it’s easier to become a habit. When substance use becomes a go-to for managing stress, it can turn into a cycle that’s hard to break. 

Peer pressure is a real thing. Social circles and cultural expectations can play a big role in the development of substance abuse. Experimentation is common during young adulthood but some people are more vulnerable to addiction due to their unique combination of genetics, personality, and social experiences. 

What’s Happening in the Brain?

Think about the brain like a vinyl record. It’s got grooves that play a tune. When drugs and alcohol enter, the brain’s reward system lights up and a new groove begins to form. With repeated use, that groove gets deeper, and a new song begins to play that’s stuck on repeat. The brain is literally rewiring itself as it stops producing feel good chemicals on its own and instead relies on substances to release dopamine and serotonin. This is what can lead to cravings, compulsive use, and withdrawal symptoms. Addiction can change how the brain perceives pleasure, making other enjoyable activities - like hobbies or spending time with friends - feel less rewarding.
