This is a collection of interactive animations about addiction and the brain. I have used this as an inquiry learning activity where I ask students to explore the different animations and reflect on the information they have found.
This video from a news broadcast describes addiction's impact on your brain. Because it is for more of a general audience than the scientific accounts some students find this information more accessible in this format.
I love this article because it is published by the Harvard Medical School. Sometimes students have strong negative preconceived notions about the nature of addiction. If students have a hard time believing the other sources the authority of the Harvard Medical School can help them start to think more objectively about the topic.
This article is a great written counterpart to the Chemistry of Addiction video as well as bringing in specific information about co-occurring addiction. There are also videos included that further these ideas with real people who have suffered from addiction.
This video describes how addiction works in the brain. I always like to focus my lessons on addiction on this aspect so that students realize both that addiction isn't just not trying hard enough as well as to explain that anyone can become addicted.
