Harmfulness of Drugs
The information about the harmfulness of drugs can be found in the following article:
Nutt, D., King, L. A., Saulsbury, W., & Blakemore, C. (2007). Development of a rational scale to assess the harm of drugs of potential misuse. The Lancet, 369, 1047–1053.
You can access the article either directly by going to The Lancet website http://www.thelancet.com/journals/lancet/article/PIIS0140-6736(07)60464-4/fulltext and filling in the registration or, if you don't want to register for The Lancet, you can access it online through the UWO library. Or, for those of you who want the tactile experience of handling a real book, you can go to the Taylor stacks and read the paper version with call number W1.LA453.
