Development of new techniques and methods for analysis of controlled substances brings a different way of considering drug analysis which is articulated for the first time in this new text. In addition to a modern treatment of the widely known drugs (eg. Cannabis, heroin, cocaine, amphetamines, ring substituted amphetamines) and pharmaceuticals which are used as recreational drugs (eg. barbiturates, benzodiazepines), the book will consider prominent drug classes that have not yet received systematic treatment in a textbook (for example synthetic cannabinoids, piperazines, cathinones, fentanyls). Aimed at undergraduate and postgraduate taught programmes, the book includes methods for drug analysis and comparison using physical, biologically based, comparative and numerical techniques. It will also serve as a reference point for research students and practising forensic scientists. It introduces statistical methods for drug sample comparison and the appropriateness of some of the statistical techniques for drug analysis and examines their use. It also considers newly developed analytical methods and significant legislative changes. Aimed at academics delivering forensic science courses in particular, it could also be used by chemistry, biochemistry, criminalistics, criminology and law and policing students on MSc forensic science courses and postgraduate research candidates.

Intravitreal injections (injections into the eye) are a new form of treatment for various conditions such as age-related macular degeneration, diabetic eye disease and vascular eye problems. The use of these injections has become so widespread that most departments around the world (and particularly in the U.K) do not have enough doctors to meet the service provision demands of an ever increasing number of patients. Many departments have trialed training ophthalmic nurse practitioners as a solution and the number of such specifically trained nurses is set to rise exponentially in the future. This book is meant to be an easy to carry A5 handbook detailing all that an ophthalmic nurse practitioner needs to know about performing the procedure. It is hoped that the book will also be of benefit to trainee ophthalmologists learning the procedure.As this is an emerging area of expertise in ophthalmology, currently there exists no other books on the topic. The readers will benefit from having a single resource detailing all that they need to know about the procedure. This means that nurses will not have to cross reference multiple complicated ophthalmic textbooks. As an A5 handbook, it will be easy to carry and reference in clinics. It is deliberately meant to be concise (around 100 pages), thus concentrating only on the core knowledge required.
