Linking Drug Use and Mental Health Problems

The connection between drug use and mental health problems impacts millions globally. In 2016, the World Health Organization reported that approximately 271 million people, accounting for 5.5% of the global population, experimented with drugs, with 31 million individuals facing drug use disorders. Simultaneously, in 2017, around 450 million people, or 6.1% of the world’s population, grappled with mental disorders, contributing to 11.5% of the global burden of disease.


The Relationship Between Drug Use and Mental Health

This relationship between drug use and mental health forms a dynamic interplay where one can shape the other and vice versa. Some individuals resort to drugs as a coping mechanism for mental health symptoms like anxiety, depression, or PTSD. However, this strategy is risky and ineffective. This is because certain drugs may initially relieve certain symptoms. However, over time, they could worsen or even introduce new mental health challenges.

And it gets worse. Some individuals have developed mental health problems due to drug use or due to the underlying factors that made them use drugs in the first place. For instance, drug use can cause changes in brain structure. This change could make a person more susceptible to mental disorders like psychosis, bipolar disorder, or personality disorders. Moreover, drug use can expose individuals to stressful or traumatic situations, such as violence or legal problems, impacting their mental well-being.

Diagnosis and Treatment

The co-occurrence of drug use and mental health problems, known as comorbidity or dual diagnosis, presents substantial challenges for diagnosis and treatment. Drug use and mental health problems usually present similar or overlapping symptoms. This makes it difficult to differentiate between the two or identify the primary and secondary disorders. As a result, a comprehensive assessment, using standardized tools, is crucial to ensure an accurate and holistic diagnosis.

Effective treatment of drug use and mental health problems necessitates a coordinated and integrated approach, addressing both disorders together. An integrated treatment that combines pharmacological and psychosocial interventions has proven successful in improving outcomes. The improvements include reducing drug use, enhancing mental health, improving quality of life, and preventing relapse. Drugs such as antidepressants, antipsychotics, mood stabilizers, or opioid agonists help alleviate cravings and withdrawal symptoms. They also help correct negative states associated with drug use, stabilize mood, and improve cognitive functioning related to mental health problems.

Psychosocial interventions, including cognitive-behavioral therapy (CBT), contingency management, motivational interviewing, or relapse prevention, play a crucial role in treatment. These therapies enhance motivation, self-efficacy, and coping skills while modifying maladaptive cognitions, emotions, and behaviors linked to drug use and mental health problems.


In conclusion, the intertwining issues of drug use and mental health demand heightened awareness, reduced stigma, and increased access to integrated prevention, diagnosis, and treatment services. Supporting individuals with comorbid disorders on their journey to recovery and well-being is paramount for both individual and societal well-being.
