Concurrent
DISORDERS

What is a concurrent disorder?

We use the term concurrent disorder (CD) when a person has significant challenges related to both mental health and psychoactive substance (PS) use. These disorders will appear at the same time and in related ways.

However, a person who uses PS and has shown some mental health symptoms (or vice-versa) does not automatically have a concurrent disorder.

Let's dive in

With the goal of furthering our understanding of the possible causes associated with a concurrent disorder (CD), please find more information on different hypotheses for its emergence below.

Each possible cause includes:

  • A presentation of the hypothesis for the origin of concurrent disorders.
  • A testimonial describing the cause.
  • One or more associated avenues for intervention.

Please keep in mind: 

  • The goal of this information is to help support workers further their reflections and to serve as an intervention aid. It can be used as a starting point for dialogue between a support worker and the person they're working with.
  • It's important not to think of the avenues for intervention as a ready-made solution. They are a tool that should be used with nuance and consideration for the perspective of the person you're working with, as well as your own understanding of the situation.
  • A concurrent disorder can have multiple causes, which are not necessarily exclusive. We may also see multiple causes associated with a concurrent disorder emerge at different stages of someone's life.
  • Someone showing symptoms of a mental health disorder and who also uses psychoactive substances does not necessarily have a concurrent disorder. Concurrent disorders are characterized by mental health symptoms and psychoactive substance use which lead to suffering and/or problems functioning.

Self-medication

A person uses PS to help ease their mental health symptoms. This alternative solution may reduce symptoms, but usually only in the short term.

For example, someone might consume alcohol to relieve their anxiety.

PS consumption can set off or accelerate intense mental health challenges, such as a depressive state, anxiety or hallucinations.

For example, a person may experience their first psychotic episode after having consumed cannabis.

Consuming alcohol or drugs could lead to negative impacts on several aspects of a person's life (relationships, work, housing, etc.). These indirect, consumption-related impacts can lead to mental health problems.

For example, excessive opioid consumption can lead to losing income and then housing, which can lead to depression.

A single element can affect someone's mental health and also lead them to use drugs or alcohol or intensify their consumption. This could be due to the person's biological or psychosocial conditions, or an emotionally or physically traumatic event.

For example, a physical assault could lead a person to develop obsessive compulsive disorder (OCD) and consume benzodiazepines.
