Harmful Substances & Addiction

Why Harmful Habits Matter

Many behaviours provide short-term pleasure, comfort, distraction, or relief.

However, some habits can gradually undermine physical health, mental wellbeing, relationships, finances, and quality of life.

These behaviours exist on a spectrum. Not everyone who drinks alcohol has a drinking problem, and not everyone who spends time on social media is addicted. Nevertheless, seemingly small habits can become increasingly influential over time.

Common Harmful Behaviours

Examples include:

  • Smoking

  • Vaping

  • Excess alcohol consumption

  • Recreational drug use

  • Gambling

  • Excessive social media use

  • Online pornography

  • Excessive gaming

  • Compulsive online behaviours

The common feature is that these behaviours can provide short-term rewards while creating longer-term costs.

Health Consequences

Depending on the behaviour, potential consequences include:

  • Cardiovascular disease

  • Cancer

  • Respiratory disease

  • Liver disease

  • Mental health problems

  • Sleep disruption

  • Financial difficulties

  • Relationship problems

  • Reduced productivity and performance

Many people underestimate the cumulative impact of small daily habits over years and decades.

Understanding Behaviour Change

Most people already know when a habit is no longer serving them.

The difficulty lies in changing behaviour.

Habits are often linked to:

  • Stress

  • Emotions

  • Environment

  • Social situations

  • Identity

  • Routine

Successful change rarely depends on willpower alone. It usually involves understanding the role the behaviour plays and developing healthier alternatives.

Harmful Habits and Men

Men are more likely than women to experience certain health risks associated with alcohol, gambling, substance use, and risk-taking behaviours.

Many men also use distraction as a way of coping with stress, uncertainty, loneliness, or emotional discomfort.

Common examples include:

  • Drinking to unwind

  • Excessive screen time

  • Gambling for excitement or escape

  • Using pornography as a coping mechanism

These behaviours often begin as solutions to a problem before eventually becoming problems themselves.

Recognising this pattern is often the first step towards change.

How Coaching Can Help

Coaching is not a substitute for specialist addiction treatment where that is required.

However, coaching can be highly effective for people who recognise that a habit is affecting their health, wellbeing, or performance and want support in making meaningful changes.

Lasting behaviour change starts with awareness, ownership, and a clear understanding of what truly matters.

Frequently Asked Questions

  • There is no completely risk-free level of alcohol consumption. Current UK guidance recommends not regularly drinking more than 14 units per week, spread over several days. Even within these limits, alcohol increases the risk of certain cancers and other health conditions. In general, less alcohol is associated with lower health risk.

  • Regular daily drinking may increase the risk of dependence and can contribute to high blood pressure, poor sleep, weight gain, liver disease, and certain cancers. Many people benefit from having several alcohol-free days each week and periodically reflecting on the role alcohol plays in their lives.

  • Current evidence suggests that vaping is likely less harmful than smoking cigarettes because it does not involve the combustion of tobacco. However, vaping is not harmless. Most vaping products contain nicotine, which is highly addictive, and the long-term health effects of vaping are not yet fully understood. For people who do not smoke, starting to vape is not recommended.

  • Yes. Some vaping devices can deliver nicotine very efficiently, and because they are easy to use throughout the day, some people consume more nicotine than they did when smoking. While vaping may help some smokers quit cigarettes, it can also maintain long-term nicotine dependence.

  • A useful question is whether the behaviour is becoming difficult to control despite negative consequences. Warning signs include repeated unsuccessful attempts to cut back, increasing time spent on the activity, cravings, withdrawal symptoms, or continuing despite impacts on health, relationships, work, or finances.

  • Yes. Gambling-related harm can affect financial wellbeing, mental health, relationships, and quality of life. Problems often develop gradually and may remain hidden for long periods. Common warning signs include chasing losses, gambling with increasing amounts of money, hiding gambling behaviour, or feeling unable to stop.

  • Social media can be a useful tool for communication and connection. However, excessive use may contribute to reduced concentration, poor sleep, lower productivity, increased stress, and unhealthy comparison with others. For some people, social media becomes a habitual distraction that consumes more time and attention than intended.

  • Not necessarily. However, excessive pornography use may affect some individuals' relationships, expectations, wellbeing, or productivity. If a behaviour feels compulsive, difficult to control, or inconsistent with personal values, it may be worth reflecting on its role and impact.

  • Successful behaviour change rarely depends on willpower alone. Habits are influenced by environment, routines, stress, social situations, and emotions. Understanding why a behaviour occurs, identifying triggers, and making gradual, sustainable changes are often more effective than relying on motivation alone.
