the anti-psychiatry movement. As many critics from within and outside of psychiatry have argued, there are many financial and professional links between psychiatry, regulators, and pharmaceutical companies. Drug companies routinely fund much of the research conducted by psychiatrists, advertise medication in psychiatric journals and conferences, fund psychiatric and healthcare organizations and health promotion campaigns, and send representatives to lobby general physicians and politicians. Peter Breggin, Sharkey, and other investigators of the psycho-pharmaceutical industry maintain that many psychiatrists are members, shareholders or special advisors to pharmaceutical or associated regulatory organizations. There is evidence that research findings and the prescribing of drugs are influenced as a result. A United Kingdom cross-party parliamentary inquiry into the influence of the pharmaceutical industry in 2005 concludes: "The influence of the pharmaceutical industry is such that it dominates clinical practice" and that there are serious regulatory failings resulting in "the unsafe use of drugs; and the increasing medicalization of society". The campaign organization No Free Lunch details the prevalent acceptance by medical professionals of free gifts from pharmaceutical companies and the effect on psychiatric practice. The ghostwriting of articles by pharmaceutical company officials, which are then presented by esteemed psychiatrists, has also been highlighted. Systematic reviews have found that trials of psychiatric drugs that are conducted with pharmaceutical funding are several times more likely to report positive findings than studies without such funding. The number of psychiatric drug prescriptions have been increasing at an extremely high rate since the 1950s and show no sign of abating. In the United States antidepressants and tranquilizers are now the top selling class of prescription drugs, and neuroleptics and other psychiatric drugs also rank near the top, all with expanding sales. As a solution to the apparent conflict of interests, critics propose legislation to separate the pharmaceutical industry from the psychiatric profession. John Read and Bruce E. Levine have advanced the idea of socioeconomic status as a significant factor in the development and prevention of mental disorders such as schizophrenia and have noted the reach of pharmaceutical companies through industry sponsored websites as promoting a more biological approach to mental disorders, rather than a comprehensive biological, psychological and social model. Electroconvulsive therapy Psychiatrists may advocate psychiatric drugs, psychotherapy or more controversial interventions such as electroshock or psychosurgery to treat mental illness. Electroconvulsive therapy (ECT) is administered worldwide typically for severe mental disorders. Across the globe it has been estimated that
