The effects of drugs and alcohol are widespread. Not only do they affect an individual, but they also have profound effects on families and broader communities. Admitting that you have a problem and being prepared to break the cycle of substance abuse is important but you also need professional help to prevent you from falling into a downward spiral of addiction.


What Is Addiction And How Does It Affect The Brain?

Addiction, whether it be to alcohol use or drug use, affects your brain by changing the way it functions, to the extent that it makes your brain dependent on the substance in question. Lots of people think they are in control of the substance, and they start and continue using it because they like the effect that it has. Very soon however your tolerance for the substance increases, and after a period, you cannot function without it. By increasing your tolerance, you will need greater amounts of the drug or alcohol in order to achieve the same feeling of euphoria, happiness or control.

What risk factors are likely to predispose you to addiction or addictive behaviours?

Some people appear to be at elevated risk of addictive behaviours. Some of the factors that may contribute to this include



Your family history plays a role in how you might respond to addictive substances. While men and women are both statistically likely to be addicted the same, if you have a family history of alcohol abuse, you will be more likely to experience it yourself.


Your Mental Health

People who are depressed, highly anxious or have difficulties with concentration are more likely to turn to substance abuse as a coping mechanism for their mental health. People who have a history of traumas are also more likely to fall into addictive cycles and substances. 17.7% of people who have substance problems also have anxiety disorders.


Emotional Alienation

Individuals who do not have close family bonds or relationships are more likely to turn to drugs and alcohol.


Effects Of Alcohol Abuse

Alcohol is legal but it can still be addictive. Over time, excessive alcohol use can lead to poor health, disease and death. It is also responsible for a broad base of social problems. Ultimately the effects of alcohol use are far-reaching and include


  • Health And Physical Problems

Alcohol is addictive and debilitating to major organs and your general state of health. Alcohol also encourages people to engage in risky behaviours that they wouldn’t otherwise consider.


  • Mental Health Problems

Alcohol use affects your mood and personality. It also affects mood and concentration.


  • Family Problems

Alcohol abuse creates and compounds family problems, resulting in overspending, violence and triangulations of family dynamics.


  • Financial Issues

Alcohol abuse is costly and unaffordable for most people. Because it causes problems with work and careers, it has a domino effect on finances. Additionally, alcohol abuse is responsible for workplace injuries and neglect.


How Does Drug Use Affect Your Brain?

Drug abuse results in a release of dopamine in your brain. It’s a feel-good neurotransmitter that gives you pleasure, and ultimately your brain wants to repeat the exercise so it encourages you to do it again. Some of the effects that drugs have on your brain include

  • Affecting your decision-making ability
  • Affecting your memory and concentration
  • Interfering with your brain’s ability to learn
  • Interfering with your judgement
