The first thing that you'll notice about this book is the size. Not only is it smaller than the average psychology textbook, it's also a lot thinner, which is surprising given the price of the book. Though it is a lot cheaper than the hardback version, which at least says something.
Despite this, as an overview of substance addiction, the book does prove rather useful. It includes sections on who becomes addicted, why we get addicted, and a chapter for each of the major drug groups. All sections come with a plethora of helpful statistics on mortality, morbidity and various other constructs which paint a nice picture of who the drug users are.
As the book is so small, it leaves out a number of things that could have been included to make more sense on a psychology course focusing on substance addiction, though the treatment based layout would most likely be very helpful for those that would need to use that during their course or job.
