Introduction to Drugs and Behavior

The majority of people regularly use a psychoactive drug of one kind or another. From your morning coffee to a glass of wine with dinner, substance use is a large part of everyday life. Some drugs are quite harmless, some are quite dangerous, and others may appear safe at the moment but can have longer-term consequences.

This course is designed to provide you with an introduction to the psychology of psychoactive drugs. You will learn what drugs are, how they work in the brain, and the principles behind addiction. We will then take an in-depth look at individual substances including alcohol, nicotine and tobacco, cannabis, cocaine and amphetamines, opioids, and hallucinogens. After completing this course, you will have obtained a greater understanding of how and why psychoactive drugs influence our behavior.
