What Is Depression?
Depression is a treatable mental health condition marked by a persistent low mood, loss of interest, and changes in sleep, energy, concentration, and behavior that last at least two weeks and interfere with daily life. It is more than sadness — it involves brain, body, and behavior, and responds to evidence-based therapy, medication, and lifestyle change.

What Causes Depression?
Depression usually arises from an interaction of biological, psychological, social, and medical factors.
Biological Causes
Genetics, neurotransmitter function, inflammation, and hormonal changes shape depression risk.
Depression and Substance Use Disorders
Depression and substance use frequently co-occur. Substances may feel like short-term relief but worsen depression over time. Integrated dual-diagnosis treatment addresses both conditions together for stronger, more durable recovery.
Alcohol & Depression
Alcohol is a depressant that disrupts sleep, lowers mood, and worsens depression over time.
Opioids & Depression
Opioid use is strongly linked to depression and overdose risk, especially during withdrawal.
Meth & Depression
Methamphetamine crashes produce severe depressive symptoms during withdrawal and early recovery.
Cocaine & Depression
Cocaine use is followed by low mood, fatigue, and anhedonia that fuels continued use.
Prescription Drugs & Depression
Misuse of sedatives, stimulants, and opioids can trigger or deepen depression.
Cannabis & Depression
Frequent high-potency cannabis use is associated with worsening depression and motivation loss.
