Quite often. General population based studies have established high prevalence rates of substance use disorders among individuals suffering from psychiatric disorders.
Similarly, persons with a substance use disorder are more likely to experience a psychiatric condition. As compared to the general population, the individuals with drug use disorders are twice as likely to suffer from a mood or anxiety disorder. Similarly, the individuals with a mood or anxiety disorder are twice as likely to suffer from a drug use disorder. Two of the largest population-based mental health surveys in the USA found that up to 37% and 53% of the respondents with alcohol use disorder and drug use disorders, respectively, had at least one comorbid psychiatric disorder.

Substance Abuse May Cause Mental Illness
1. It has been observed that abuse of psychoactive substances, especially if excessive and/or prolonged, can lead to the emergence of psychiatric disorders.
Cannabis use has been associated with an increased risk of psychotic disorders in a dose-dependent manner.

2. Additionally, psychiatric symptoms can emerge during multiple stages of use - like extreme intoxication and withdrawal - from certain psychoactive substances.
- There is evidence to support that the use of certain psychoactive substances can trigger the underlying biological vulnerability for psychiatric disorders.
- Such observations have been made in the genetic and biochemical studies that have explored the underlying mechanisms of emergence of psychiatric disorders among individuals with drug use disorders.
3. Additionally, the mental health complications associated with alcohol and drug use could act as a stressor and contribute to the emergence of psychiatric issues like depressive disorder and anxiety disorders.
- It has been documented that use of alcohol and other drugs can worsen the psychiatric symptoms and even induce re-emergence of the symptoms among those who are in remission.
Substance Abuse May Be an Attempt to Escape the Symptoms of Mental Illness
The self-medication hypothesis of drug use among patients with psychiatric disorders states that individuals with psychiatric disorders may attempt to reduce their 'tension' by using psychoactive substances.
- For example, those with social anxiety disorders may resort to alcohol use in order to address the anxiety experienced while interacting with others.
- Similarly, individuals experiencing distressing symptoms such as auditory hallucinations may use substances to avoid the distress.
- Some individuals also report the use of psychoactive substances in order to manage the adverse effects associated with psychiatric medicines prescribed for the treatment of the underlying mental health condition.
- Self-medication in anxiety disorders has been associated with a substantial risk of developing a substance use disorder.

Substance Abuse and Mental Illness Share a Common Cause
There is a growing body of evidence that suggests that psychiatric disorders and substance use disorders might share a common etiology.
It has been postulated that common genetic factors might be shared across the psychiatric disorders and substance use disorders.For example, a common genetic susceptibility may explain dopamine dysregulation in substance abuse and mental illness.
Various environmental factors are also shared across psychiatric disorders and substance use disorders.Early childhood trauma, stress and early exposure to psychoactive substances have been identified as predisposing factors for both psychiatric disorders and substance use disorders.
Similar brain regions have also been implicated in the development of psychiatric disorders and substance use disorders.Neurological mechanisms involved in stress response and dopaminergic regulation have been identified as precipitating factors in both psychiatric disorders and substance use disorders.
Substance Abuse and Mental illness Maintain Each Other
While psychiatric disorders and substance use disorders can co-occur as independent disorders in the same individual, in a subset of a dually diagnosed population these two sets of disorders also contribute to the maintenance of each other.
Similarly, the psychiatric issues that emerge consequent to the use of a psychoactive substance can then lead to reinforce continued or even excessive use of the psychoactive substance.
