In the UK around 500 soldiers each year get fired because they fail drug-testing. The substances they use are mainly recreational drugs like cannabis, XTC, and cocaine. Some call this a waste of resources, since new soldiers have to be recruited and trained, and call for a revision of the zero tolerance policy on substance use in the army.
This policy stems from the Vietnam war. During the First and Second World War, it was almost considered cruel to deny soldiers alcohol. The use of alcohol was seen as a necessary coping mechanism for soldiers facing the horrors of the battlefield. The public opinion on substance use by soldiers changed radically during the Vietnam War. Influenced by the anti-war movement, the newspapers then were dominated by stories of how stoned soldiers fired at their own people, and how the Vietnamese sold opioids to the soldiers to make them less capable of doing their jobs. Although Robins (1974) provided evidence that the soldiers used the opioids in a relatively safe way, and that they were enhancing rather than impairing the soldiers’ capacities, the public opinion on unregulated drug use in the army was irrevocably changed.

On Thursday 16th October, Professor Kenneth Kendler delivered his second (and final) Loebel Lecture, entitled ‘The dappled causal world for psychiatric disorders: implications for psychiatric nosology’. You can view it online here or listen here.
Whilst Kendler’s first lecture – summarised by Roger Crisp here – focused on empirical issues, the second lecture was more philosophical. Kendler’s key question in the second lecture could perhaps be formulated as: Given the complex aetiology of mental disorders, how can we best understand and explain how they arise? Continue reading
The Genetic Epidemiology of Psychiatric and Substance Abuse Disorders: Multiple Levels, Interactions and Causal Loops
What causes psychiatric disorders, such as depression or alcohol abuse disorders? It’s obvious that background and upbringing often play a significant role, as do life events, such as losing one’s spouse or one’s job. And we also know now that genetic propensities are important. But how do these different factors inter-relate with one another? For over three decades, these issues have been at the centre of the research of Oxford’s first Loebel Lecturer, Professor Kenneth Kendler.
Professor Kendler is one of the world’s leading, and most highly cited, psychiatric researchers. He uses a range of methods, including family studies, twin and adoption studies, and molecular genetics. He also has a serious interest in the philosophy of psychiatry. His first Loebel Lecture — The Genetic Epidemiology of Psychiatric and Substance Abuse Disorders: Multiple Levels, Interactions and Causal Loops – was presented at the Oxford Martin School on Wednesday 15 October 2014, and is now available on Youtube and as an MP3 audio file.
