Understanding Addiction
Addiction, clinically known as a Substance Use Disorder (SUD), is a complex condition—a brain disease that is manifested by compulsive substance use despite harmful consequences. People with addiction (severe substance use disorder) have an intense focus on using a certain substance(s), such as alcohol, tobacco, or illicit drugs, to the point that it takes over their life. Addiction changes how the brain functions, making quitting highly difficult, even for those who want to.

Common symptoms
Symptoms vary in severity and presentation. Diagnosis is made only when they significantly affect daily life over time.
- Feeling that you have to use the substance regularly (daily or even several times a day)
- Having intense urges for the substance that block out any other thoughts
- Needing more of the substance to get the same effect (tolerance)
- Failing in your attempts to stop using the substance
- Spending money on the substance, even though you can't afford it
- Experiencing withdrawal symptoms when you attempt to stop taking the substance
Possible causes
Mental health conditions rarely have a single cause — they arise from a mix of biological, psychological and social factors.
- Brain changes: Substances can alter the brain's reward system, changing how you feel pleasure, motivation, and self-control.
- Genetics: Your genetic makeup can account for a significant portion of your vulnerability to addiction.
- Environment: Peer pressure, family beliefs and attitudes, and exposure to a peer group that encourages substance use.
Risk factors
Certain factors may increase the likelihood of developing this condition:
- Family history of addiction
- Mental health disorder (depression, ADHD, PTSD)
- Early use of substances
- Lack of family involvement or support
How it is evaluated
A psychiatrist specializing in addiction will conduct a thorough evaluation, which includes a review of your substance use history, a medical history, and an assessment of your mental health, as addiction frequently co-occurs with other mental health conditions (dual diagnosis).
When to seek help
If your substance use is causing problems in your life (at work, in relationships, or with your health), or if you've tried to quit but couldn't, it's time to seek help. Recognizing the problem is the first and often hardest step.
Evidence-based treatments
Treatment is highly individualised. A combination of therapy, medication and lifestyle support is usually most effective.
Medical Detoxification
The first step is often medically managed withdrawal to safely clear the substance from the body and manage severe withdrawal symptoms.
Medication-Assisted Treatment (MAT)
Medications can be used to re-establish normal brain function and decrease cravings, particularly for opioid or alcohol addiction.
Behavioral Therapies
Therapies like CBT help patients recognize, avoid, and cope with the situations in which they are most likely to use substances. Family therapy helps repair relationships and build a support system.
