Introduction

The word "addiction" evokes strong emotions and often carries negative connotations. And it’s important to note that not every change in drinking habits suggests an addiction. Some individuals might choose to drink less to maintain a clear mind or simply wish to reduce their weekly intake. These are valid reasons for taking a break from alcohol or adopting an alcohol-free lifestyle, irrespective of the frequency or quantity of consumption. The term "addiction" certainly doesn’t apply to everyone, but if any level of alcohol consumption becomes a concern, it’s worth exploring the underlying reasons.

Recognizing this, the article might be better titled "Why We Drink: Genes or Environment?" Our relationship with alcohol is a multifaceted issue, deeply intertwined with genetic predispositions and environmental influences. Understanding this dynamic is crucial in addressing alcohol use, which is increasingly recognized under the broader term "substance use disorder." This shift acknowledges that the substance, not the individual, is often the central issue, offering a refreshing perspective that moves away from outdated labels like "alcoholic."

The Substance Problem: Alcohol

Alcohol stands as one of the most widely consumed and profitable addictive substances. The global alcohol market was valued at approximately USD 2,313.2 billion in 2023 and is projected to grow significantly by 2032 (1). With such financial power behind the industry and pervasive cultural messages suggesting alcohol as integral to daily life, it’s unsurprising that its consumption is so widespread. Despite this normalization, alcohol is inherently addictive, altering the brain's reward systems and decision-making processes.

The term "substance use disorder" emphasizes that it is this addictive potential, rather than a personal flaw, that often leads to issues with alcohol consumption. Acknowledging this perspective is crucial in reducing stigma and fostering healthy relationships with alcohol.

Environmental Influences

Environmental factors, such as where we live, our social circles, and surrounding influences, play a crucial role in the development of any addiction—be it to alcohol, drugs, or even food. A study involving Vietnam War veterans revealed how the environment impacts addiction. While many soldiers became addicted to substances like heroin during their service, a significant number overcame these addictions upon returning to a non-conflict environment, often without formal treatment. This underscores the powerful role that changing environments can have on substance use behaviors. Family habits, peer pressure, and socio-economic conditions add further complexity to these influences.

The Role of Beliefs and Habits

Our beliefs and habits significantly shape our relationship with alcohol. Cultural narratives often suggest that alcohol is necessary for relaxation, celebration, or coping, while established routines, such as Friday night in the pub, can reinforce consumption patterns.

However, being part of a positive community that values health and low or no alcohol consumption can shift these beliefs and habits. By reframing our environment, adjusting our routines, and deconstructing long-held beliefs, adopting an alcohol-free lifestyle (or a break from alcohol) becomes more attainable.

Genetic Factors

Our understanding of genetics, particularly nutrigenomics, is advancing, offering new insights into how genes influence addiction. There is no singular "addiction gene." Instead, various genes interact to affect our vulnerabilities and behaviors. These genetic expressions can be likened to a dimmer switch, influenced by environmental factors.

Pathways for neurotransmitter production and breakdown, involving dopamine, serotonin, and others, are affected by numerous genes. Lifestyle factors, nutrition, and environmental toxins further alter these pathways' efficiency. While genes provide potential, it is often the environment that triggers substance use.

Holistic Understanding

To truly understand why we drink, acknowledging the interplay of genetics and environment is essential. Both factors influence individual choices and behaviors, contributing to substance use.

By embracing this complexity, we can develop holistic strategies that include environmental changes, habit and belief assessment, and biohacking our physiology with personalized genetic approaches. Which is truly exciting! Working on emotion-led behaviour change allows us to envision a new lifestyle - crafting a life that we don’t want to escape from.

Conclusion

Understanding the interplay between genetics and the environment can empower us to make informed decisions and create personalized plans for change.

This transformation IS always possible, regardless of background or genetic predispositions, paving the way for healthier lifestyles and new beginnings.
