| 説明 | Red means a drug is the most harmful in that category, green that it is the least. Data from Nutt et al, 2007. Visualisation by Dr Andy Pryke, The Data Mine Ltd*Background*In March 2007, a paper on the dangers of different drugs hit the news headlines. The paper was "Development of a rational scale to assess the harm of drugs of potential misuse" by David Nutt, Leslie A King, William Saulsbury, and Colin Blakemore.The paper measured the harmfulness of 20 substances on 9 different measures.I transformed the data into a simpler to understand form. In the visualisation below, Red means most "danger", yellow indicated less of a problem and green the least harm. The grey square for "intravenous use of alcohol" indicates that no score was given for this. I also re-arranged the rows and columns so that similar drugs appeared next to each other. You can trace these similarities in the tree on the left.For example, the red and dark orange rows across the centre of the diagram clearly show how heroin and cocaine are ranked as particularly dangerous across the board. However, at the bottom of the diagram, tobacco is particularly bad in terms of long term (chronic) effects and healthcare costs but much less harmful in terms of it's social and intoxicant effects. I plan to visualise data from the 2010 paper once I get hold of it - if you can help, please let me know. |
