The lecture on drugs did not just explore addictive substances that affect people, but it also went into addictive behaviors such as exercise or gambling. As someone who has personally witnessed what drug addiction can do to a person and their family, I found this lecture very interesting. For example, to see how the frontal lobes and dopamine functions helped deepen my understanding of the effects of drugs and other dopamine producing things on the brain. Also, it was interesting to learn that certain personality traits and genetics may increase an individual’s vulnerability to experimentation with drugs and even addiction. Now I see where the term “addictive personality” comes from. Towards the end of the lecture there was a connection made between addictive effects of drugs and exercise, two things I would not normally put together but I can see how reinforcement, tolerance, and withdrawal work in both.
