Reference excerpt

This is a list of countries, and some territories, by the annual prevalence of opiates use as percentage of the population aged 15–64, unless otherwise indicated.

Methodology The primary source of information are the World Drug Report 2011 (WDR 2011) and the World Drug Report 2006 (WDR 2006), published by the United Nations Office on Drugs and Crime (UNODC). The indicator is the "annual prevalence" rate which is shown as the percentage of the youth and adult population who have consumed the drugs at least once in the past year. In 2009, the largest producer of opiates in the world was Afghanistan, with 93% of the world's market. The list does not include opioids, classified as a different drug under the World Drug Report 2011 list, which is considered "opiates and prescription opioids."

Worked examples

Example 1 — a first encounter with List of countries by prevalence of opiates use

Start with the simplest possible case. Write down what List of countries by prevalence of opiates use claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to List of countries by prevalence of opiates use before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about List of countries by prevalence of opiates use ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of List of countries by prevalence of opiates use

In research: List of countries by prevalence of opiates use appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses List of countries by prevalence of opiates use in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
