3. External Addiction Factors
About this Lecture
In this lecture, we continue the discussion of factors influencing who becomes addicted, focusing in particular on: (i) the two primary external factors of family and peer influences; (ii) outlining family influences as coming in a variety forms, exploring the two primary mechanisms of behaviour modelling and addictive substance availability; (ii) peer influences, an external factor often taking centre stage during talks on drug use, abuse and addiction; (iv) the doubling effect of particular personality types, the example given being that an impulsive individual who may already be more prone to developing an addiction is also more likely to have impulsive friends, who could increase the likelihood further.
In this course, Professor Marcus Munafò explores addiction in the context of smoking and smoking cessation. In the first lecture, we think about some key physical and psychological withdrawal symptoms of smoking, before exploring the fact that the positive outcomes of smoking may be simply an absence of these withdrawal symptoms. In the second and third lectures, we explore the internal and external factors which can influence the likelihood that someone may become addicted to a substance. In the fourth and fifth lectures, we continue this differentiation between internal and external factors, discussing internal, biological mechanisms of addiction and external, learning mechanisms. In his final note, Professor Munafò brings forward the idea of understanding addiction as a disorder of learning.
Marcus Munafò is a professor of biological psychology and associate pro vice-chancellor of research culture at the University of Bristol. Professor Munafò’s research is focused on understanding health behaviours related to tobacco and alcohol use, informing current debates on tobacco product packaging. With experience in an array of research methods, one of Professor Munafò’s other interests is in whether participant incentives in scientific experiments provide an optimal level of robustness and reproducibility. Some of Professor Munafò’s recent publications include ‘Acceptability of integrating smoking cessation treatment into routine care for people with mental illness’ (2022) and ‘Applying Mendelian randomization to appraise causality in relationships between nutrition and cancer’ (2022).
