Gabor Maté, a Canadian physician and author born in January 1944, has focused his work on childhood development, psychological trauma and their long-term effects on health. His five books examine addiction, stress, developmental psychology and attention deficit hyperactivity disorder. Central to his approach is addressing the emotional pain that he believes lies behind many addictive behaviors. His clinical work has been accompanied by debate over the scope of his claims and whether they are supported by sufficient scientific evidence.
He was born in Budapest into a Jewish family during World War II. His maternal grandparents were murdered at Auschwitz when he was five months old, his aunt disappeared during the war and his father was subjected to forced labor by the Nazis. When he was one year old, his mother entrusted him to a stranger for more than five weeks to save his life. He has described this separation as an experience of abandonment, rage and despair, which he links to conflict and fears of abandonment in his adult life and marriage.
His family immigrated to Canada in 1956, and Maté studied at the University of British Columbia in Vancouver. He initially spent several years teaching English and literature at secondary school before returning to university and earning a medical degree in 1977. He ran a private family medical practice in East Vancouver for more than twenty years and served for seven years as medical coordinator of the palliative care unit at Vancouver Hospital. In 1969, he married artist Rae Maté, with whom he had three children.
For twelve years, he worked as a physician at the Portland Hotel Society, a nonprofit supportive housing organization, visiting residents in their rooms. Most of his patients faced both mental health and substance use problems, as well as chronic conditions such as HIV infection. Alongside the organization's founder, nurse Liz Evans, he contributed to harm reduction initiatives and efforts to provide housing as a first step in support, including needle exchanges and supervised injection. He provided methadone without requiring participation in treatment programs and did not stop prescribing it when a patient tested positive for illegal opioids.
He described these experiences in his 2009 book In the Realm of Hungry Ghosts: Close Encounters with Addiction, examining substance use as a way of coping with pain and the consequences of abuse and neglect. He defines addiction as substance use or repeated behavior that offers short-term relief but causes negative long-term consequences. This broad definition includes gambling, work, food and social media, as well as substances. He argues that punishment and social exclusion worsen addiction, while his books and lectures emphasize relationships and the interaction of biological, psychological and social factors.
In 2010, he became interested in ayahuasca and its potential applications in treating addiction, organizing therapeutic gatherings lasting several days with a traditional healer from Peru. Some gatherings were studied by researchers from the University of Victoria and the University of British Columbia. Preliminary results from the observational study showed statistically significant improvements in some psychological measures and a reduction in problematic substance use; this is limited, preliminary evidence. In 2011, Health Canada warned that it could refer the matter to the police because of the use of the illegal substance.
His emphasis on trauma has drawn criticism from experts who believe he gives it too much explanatory weight. Psychologist Stanton Peele, while appreciating his work at the supervised drug consumption facility Insite, describes the search for childhood trauma behind every case of addiction as reductionist. Professor Nick Haslam considers the portrayal of trauma as the single primary cause of poor health unbalanced, while other academics question the evidence behind parts of his work. His public attribution of psychiatric diagnoses to Prince Harry in 2023, based on his autobiography and an interview, drew separate criticism: experts stressed the need for a structured clinical assessment.
Maté has also spoken publicly about Israel and Palestine. In a 2014 opinion article, he argued that Israeli policies were incompatible with a just peace and compared the situation in Gaza to the Warsaw ghetto, citing the vast imbalance of power. In 2023, he called for an end to the occupation and persecution of Palestinians and the return of territories occupied since 1967. His honors include a City of Vancouver award in 2011, his appointment to the Order of Canada in 2018 and the 2023 Vine Award for The Myth of Normal, which he coauthored with his son Daniel Maté.
