Dedication
The ‘Journey’ is one of the great themes of literature. It is said that a journey
of exploration starts from the known and travels to the unknown, whereas a
journey in science goes from the unknown to the known. My own journey has
been an adventure in the exploration of science. This book is dedicated to my
grandchildren: Jude, Toby, Tom and Emily. Whatever their chosen careers, I
hope that their journeys through life are also good adventures.

Preface to the 2nd Edition
Part of my work in the Home Office Forensic Science Service (FSS) involved
the examination of drug-r elated items submitted by law enforcement agen-
cies to determine if there was evidence of an offence under the Misuse of
Drugs Act, 1971 (MDAct). If that process required no more than a compar-
ison of analytical results with a table of controlled drugs then there would
be little need for this book. In reality, the chemistry of drug legislation has
a complexity sufficient to challenge some chemists, let alone the lay person,
while some areas of the drug laws are rarely explored.
That Act came into force in 1973, and within a few years a substantial
body of case-l aw and scientific interpretation had rapidly accumulated. To
keep up to date in those early days, my colleagues and I annotated our cop-
ies of the Act with a succession of Modification Orders as well as collecting
an expanding folder of loose notes on reported cases, legal interpretation
and other aspects. Some years later, this material found its way into a set of
lectures. After retiring from the FSS, those notes were pulled together into
a 2003 book (see Bibliography), the purpose of which was to set out those
technical complexities in drugs legislation as seen from the viewpoint of a
forensic chemist. That short monograph was superseded by the first edition
of this book, published in 2009 (see Bibliography), which continued with
those same objectives.
Drug misuse continues to have a high political and public profile. Because
of the large number of offenders regularly prosecuted, drugs legislation is
subjected to regular scrutiny by the Courts. There is a need for all participants
in the legal process of drug control – lawyers, criminologists, law enforce-
ment officers and those involved in drug regulation – to have a basic familiar-
ity with the underlying chemical principles. It is hoped that at least some of
the content is accessible to non-s cientists. For chemists, the extensive use of
molecular structures in the text allows a complete and easier comprehension

viii Preface to the 2nd Edition
of the chemical background to the legislation, although some of the generic
definitions can seem hard going. This book is intended to provide that back-
ground understanding and complements other publications that deal pri-
marily with legal interpretation and the case law that has built up over the
past 50 years. In the latter respect, the reader can do no better than refer to
the comprehensive publication by Rudi Fortson QC (see Bibliography).
All jurisdictions have to address the question of whether certain activities
with certain substances should be penalised and if so whether some sub-
stances should attract heavier penalties than others, regardless of whether
those penalties are defined in the criminal law or are civil penalties or merely
administrative sanctions. The King James Bible (Proverbs 13 : 14) tells us that
‘The law of the wise is the fountain of life…’: an inscription in the Central Crimi-
nal Court in London. Most would accept that modern laws controlling harm-
ful substances reflect our wisdom. Yet within that broad acceptance, there is
continued debate about which substances should be included and what the
penalties for offences should be. Part of that concern lies in the reasons for
control. One might believe that restrictions on certain drugs are a rational
response to the relative harm of substances, whether that means harm to the
individual or to society. However, it is clear that drug legislation has been,
and continues to be, guided more by moral imperatives. Thus, the preamble
to the United Nations Single Convention on Narcotic Drugs (1961) sets the
tone by referring to the ‘evil of drug addiction’.
It is also apparent that controls on some substances reflect not just a moral
viewpoint but some misguided measure of perceived harm. Thus, the rela-
tively harmless hallucinogenic drugs (e.g., ‘magic mushrooms’) are treated as
if they were as dangerous as heroin or cocaine. Unlike in most other areas of
public health, the minimisation of harm from drugs does not appear to have
a similar high priority. A growing body of academic work leads to the conclu-
sion that the classification system in the MDAct and the International Trea-
ties does not reflect the relative harmfulness of those substances. Extreme
examples of this disconnect are alcohol and tobacco, particularly in many
Western countries; both lie outside conventional drug control. While their
sale and consumption is certainly restricted to varying degrees, penalties for
transgression are minor compared to those that operate on often less harm-
ful drugs. Such is the social acceptance of alcohol and tobacco that there is a
general reluctance to even see them as psychoactive drugs, but together they
cause far more damage to society and to individuals than all of the scheduled
substances combined.
An opportunity has been taken to rearrange, update and expand the mate-
rial in the 1st Edition. Inevitably, this book will also become dated, but it is
hoped that some of the content has lasting value. But, while it is still neces-
sary to anchor much discussion around the domestic legal and epidemio-
logical situation, attention is also paid to developments at the international
level as illustrated by the various United Nations Conventions and suprana-
tional role of the European Monitoring Centre for Drugs and Drug Addiction
(EMCDDA).
Preface to the 2nd Edition ix
In the title of this book, ‘Substance Misuse’ refers strictly to offences
such as possession, supply, importation and production; it does not include
areas such as the administration of poisons to self or others, criminal dam-
age caused by chemical substances or acts such as driving a vehicle while
impaired through alcohol or other drugs. No detailed account is provided of
epidemiology, pharmacology, toxicology, or the wider social aspects of drug
abuse, but the interested reader is directed to the Bibliography. Selected ref-
erences to specific legislation and research publications are included at the
end of each Chapter, but these are not meant to provide an exhaustive review
of the subject matter. Because they are mentioned so frequently in various
Chapters, there are no text citations to the MDAct 1971 or the three United
Conventions of 1961, 1971 and 1988. However, these are included in the
Bibliography, together with links to much background information on the
general chemistry of the substances described. Extensive background infor-
mation on new psychoactive substances is available on the EMCDDA website
and, for those in the European Union (EU) with access, the European Data-
base on New Drugs (EDND). The United Kingdom is no longer a member of
the EU; for this reason, certain information from EMCDDA is complete only
up to December 2020.
There is no discussion of the arguments for or against legalisation, depe-
nalisation or decriminalisation of some or all drugs, or to what extent drug
misuse is a health problem as opposed to a law enforcement issue. This book
is not a guide to general aspects of the law, stated cases, sentencing policy
or related legislation. It is also beyond the scope of this book to provide any
recommendations on the presentation of evidence in Court or how results
should be set out in reports and statements. Analytical properties of the
major drugs are only provided where they have a bearing on interpretation.
Some aspects of synthesis are covered in the sections concerned with precur-
sor chemicals.
