This was an extremely interesting presentation of what drugs are used in society, how the brain reacts and addiction commences within an individual, what the risk factors predispose an individual to addiction. Interesting to understand the brain and how it influences addiction, what models were identified that may explain addiction, why some people are more prone to addiction than others and the support required for people who are addicted.

The educator had a sound knowledge of the subject and presented in a clear,confident and concise manner. One of the people in the lecture was annoying in the background making her own comments.
