Welcome to Module 1! This week's material starts by looking at seemingly simple questions such as : « what are drugs ? » and « why do people use drugs ? » It then addresses the question : « why are drug internationally controlled ? » As you will see the answer to this question constitutes one of the founding blocks of the rest of this course. You will learn what legal elements make up the international drug control framework and what that means for countries putting in place different drug policies around the world. Once you have finished this week, you will be able to: explain what drugs and controlled substances are; describe the main elements of the International Drug Control Framework and recognize the diversity of national drug policies under a unique International Drug Control Framework. We hope that you are prepared to work through the interesting and wide-ranging material we have prepared for you. We also encourage you to stop and answer as many of the in-video (or stand-alone) reflective questions we have placed throughout the week, and look forward to receiving any feedback you may have for us! Have a great first week learning about drugs and the international drug control framework! Best wishes,The Drugs, Drug Use, Drug Policy and Health team

Welcome to Module 2 ! This week is all about epidemiology and drug use. Indeed, it seems pretty obvious that when looking at drug use around the world, we need to know what we are talking about ; but as you will see, for various reasons, it isn’t always that easy. You will also hear from people who use drugs, telling you about the stigmatisation they often face as well as from scientists who will share their knowledge about how drugs should be classified according to their harms and what the benefits and harms of taking certain drugs are. You will also learn what dependence really means and what health-related issues can sometimes arise with certain drugs and forms of drug use. By the end of the Module you will be able to : • Recall facts, figures and misconceptions about drug use; • Categorize drugs and their relative harms; • Describe problematic drug use and dependence and their negative consequences for individuals and the community. Don’t forget to have a look at the additional optional resources. We hope this week challenges a number of ideas you may have about drug use and their benefits and harms for example; and that you learn a lot about questions related to drugs and health.

Welcome to Module 3 which focuses on public health, harm reduction and treatment. In this Module you will see how public health policies address drug use ; become familiar with various harm reduction concepts and tools and learn a bit about the history as well. You will learn a lot about harm reduction itself, seeing how it can fit into existing health policies and look at how policies can include prevention, harm reduction and treatment in a complementary fashion. By the end of the Module you will be able to : • Recall the concepts and list the tools of harm reduction.• Assess treatment options for dependence• and Explain how prevention, harm reduction and treatment complement each other.We hope this week will provide you with a good sense of what harm reduction is and how it fits within wider public health–oriented policies. This week also builds on what you have learnt in Module 2, with regard to certain health issues and looking at when treatment for dependence may be necessary. Don’t forget to go through the essential reading list and look at the optional additional resources. Best wishes,The Drugs, Drug Use, Drug Policy and Health team

Welcome to Module 4 which looks at questioning prohibition-based policies. In this Module, you will discover that most drug policies in the world are based on prohibition law enforcement and criminalization of drug use ; and see that such policies have a number of negative consequences on people’s health as well as on their human rights. This Module will also look at law enforcement more closely and reveal how it can cooperate to improve health. You will learn about the human rights framework and the drug control framework and see what human rights violations, stemming from the implementation of prohibitionist drug policies, look like around the world. Finally, you will also see that drug policies are connected to development and the environment, most often not in a good way, with prohibition fueling violence, crime and corruption and impeding development. By the end of this Module you will be able to: • Evaluate the extent to which prohibition-based policies have succeeded or failed in reducing drug production, trafficking and consumption; • Describe the negative impacts of prohibition-based policies on health, human rights and development; • Recall how prohibition-based policies fuel organized crime and trafficking. We hope this week will provide you with valuable insight into the reality of prohibitionist drug policies, for people in communities all over the world ; and help you see what have been the consequences of these policies, in terms of their impact on human rights, health and development. We also hope you enjoy the essential reading and optional additional resources we have prepared for you. Best wishes,The Drugs, Drug Use, Drug Policy and Health team
