There are many kinds and types of drugs and they work in different ways with different results and consequences. And there is not always general consensus as to the definitions.

When we say the word drugs we typically think of hard drugs such as for instance heroin or cocaine, but there are many other drugs and there are those who would claim that ordinary tobacco is a drug too.

Most drugs have a dark side, especially if one is not careful. Many drugs can cause mental and physical addiction as well as both mental and physical disorders and problems.

Keynote speakers on drugs take a look at these and related topics, focusing maybe on drugs and medicine, on drugs and politics, on drugs and history, etc.
