Psychiatric drugs are assumed to exert beneficial effects by acting on abnormal brain processes or diseases.
- Antipsychotics: Believed to reverse the pathology of psychotic symptoms or schizophrenia.
- Antidepressants: Thought to act on biological processes causing depression.
- Mood Stabilizers: Aimed to normalize processes producing abnormal mood swings.
The prevailing assumption is that these drugs work by helping to normalize an underlying brain disorder, often described as rectifying a "chemical imbalance."
- This view is widely promoted by the pharmaceutical industry.

Joanna Moncrieff challenges the traditional assumptions about how psychiatric drugs work.
- Proposes an alternative explanation: drugs are psychoactive substances that induce characteristic artificial mental and physical states.
Distinction between:
- Disease-Centered Model:
  - Drugs correct abnormal brain states.
  - Effects are differentiated into therapeutic (beneficial) and side effects.
- Drug-Centered Model:
  - Drugs create altered physiological states.
  - Benefits arise from entering an altered, drug-induced state.
  - No clear distinction between therapeutic effects and side effects.
Philosophical Implications: This perspective aligns psychiatric drugs with recreational drugs, suggesting they produce varied mental states influencing thoughts, feelings, and behaviors.

Prior to the 1950s, low interest in psychiatric drug treatment existed, with drugs seen as either sedatives or stimulants.
The introduction of drugs like chlorpromazine and iproniazid sparked enthusiasm, but initial views were consistent with drug-centered models.
- Early understandings credited drugs for inducing abnormal neurological states mimicking Parkinson’s disease.
Transition to disease-centered treatments was not evidence-based but stemmed from psychiatric professionals' desire to align psychiatric treatments with physical medicine approaches.

Placebo-Controlled Trials: Do not differentiate drug action models; they only illustrate drugs' effects versus placebos.
Lack of known biological mechanisms underlying psychiatric disorders undermines the disease-centered model.
- Hypothetical causes, like dopamine involvement in schizophrenia, remain unproven.
Research inconsistencies indicate that the dopamine hypothesis lacks conclusive evidence linking it directly to psychotic disorders.

Drugs presumed to have disease-specific effects should outperform nonspecific ones.
- Randomized studies show various non-antidepressant drugs outperform placebos, suggesting broad potential outside traditional classifications.
Comparative studies do not consistently support the superiority of antidepressants or antipsychotics over other sedatives.
- Opiates are noted for their antipsychotic properties without significant differences in efficacy compared to traditional treatments.

Calling for more recognition of the drug-centered model challenges conventional psychiatric practices.
Advocating for drug effects based on subjective experiences may lead to more comprehensive approaches to treatment.
Understanding the types of states induced by various psychiatric drugs can inform patient choices regarding treatment options.

Antipsychotics: Tend to create states of mental and physical slowness, emotional blunting, and can effectively suppress psychotic experiences but do not remove them entirely.
Antidepressants: Wide variety in classes leads to different drug-induced states, often resulting in sedation, emotional numbness, and other adverse effects.
Evaluating Treatments: Weighing risks versus benefits is crucial to empower patients regarding psychiatric drug use.
- Important to understand potential long-term consequences and subjective effects of medications.
- Ethical considerations surrounding the administration of drugs that may only suppress emotions and not treat underlying issues need to be highlighted.

Abandoning the disease-centered model raises critical questions about conceptualizing mental illness as mere biological issues.
A drug-centered approach could reduce unnecessary medication use and potentially harmful treatments.
Promoting an understanding of drugs as foreign substances alters perceptions of mental illness and the necessity for treatment.
