Definitions: legal highs and NPS
Types: by source and effects
Legal response
Recent research: prevalence, trends
Conclusions
Definitions: legal highs
(1) Chemicals which alter the normal functioning of the brain
(neurotransmitters and brain-waves), thus producing
changes in our experience and behaviour - a ‘high’
(2) Specifically, a legal high is a chemical which is:
(a) not controlled by the 1971 Misuse of Drugs Act;
(b) not licensed for legal use (like alcohol and tobacco);
(c) not advertised/sold – and therefore not regulated - as
a medicine (Medicines Act 1968) – see next 2 slides;
(d) mimics the effects of popular controlled drugs [?]
Thus, a legal high is a substance which is not legally regulated
– a more accurate term would be ‘legal loophole’ drugs.
Novel psychoactive substances (NPS)
Over the last few years, the term ‘legal high’ has become
replaced by ‘novel psychoactive substance’ (NPS) – because
if and when possession and trafficking of a particular new
drug is prohibited by the government, it literally ceases to be
a ‘legal high’.
For example, use of the term ‘NPS’ allows us to avoid the
confusion which currently exists in relation to drugs like
mephedrone (meow/m-cat), which was banned by the UK
government in April 2010 - but it is still referred to as a ‘legal
high’ by some sources (notably the mass media).
However, it could also be argued that labels like new drugs or
novel highs are enough for many purposes.
In short:
Legal highs: uncontrolled, but can be new drugs
(eg. 6-APB) or older drugs (eg. nitrous oxide)
NPS: new, but can be uncontrolled (eg. 6-APB)
or controlled (eg. mephedrone)
The legal loophole used by NPS
Headshops and online retailers of ‘legal highs’/NPS get
round the 1968 UK Medicines Act by stating that their
products are not for human consumption, i.e. by
definition not a medicine. So: no tests/trials required.
Instead product packaging typically contains a cross/bones
(sign of toxicity), and a warning not to consume the
substance – using euphemisms such as bath salts, pond
cleaner, room odoriser, incense, cream dispenser refills
– and the vaguer product descriptors ‘souvenirs’ and
‘research chemicals’.
Packaging also typically states ‘for sale to adults only’.

Research Chemicals
November 2013
Since the ban on all arylcyclohexylamines last
year there has never been a product to fill that
void in the market for things like mxe, 4-meopcp, n-ethyl-ketamine etc etc. - Until now!
Diphenidine is a novel chemical which fills that
gap perfectly. Its not expensive either and when
researched in amounts from 50-100mg it
produces beautiful results similar to that of the
old recently banned products.
Only £20/1g so click here to give it a go!

Although phenethylamines are controlled in the
UK, the bk analogs of these compounds are not
and so bk-2C-B was born. 100mg is the ideal
amount based on initial feedback.

Problems with legal high/NPS sales
Headshops/websites cannot give out information about
the safer use of the drugs they sell
No testing/trials of risks & harms of NPS sold
No guarantee that different batches of same product will
contain (a) same dose of drug, or (b) even same drug
Huge variety of NPS available, with different chemical/
trade/slang names, making drug/health service
responses & research work very difficult
2. Types of legal high/NPS
Based on last-year prevalence of use among young adults
in 2012/13 in England & Wales (British Crime Survey):
What are the most popular legal highs?
What are the most popular NPS among those
banned since 2005?

Nitrous oxide: whippets
Nitrous oxide (N2O, laughing gas)
Young adults in UK report N2O as most popular legal high in
online and media surveys (see later slides on prevalence)
16-24 year olds: N2O is 2nd most popular of all drugs used in last
year in 2012/13 CSEW – reported by about 400,000 (6%) in
E&W – only cannabis use is more prevalent
Yet:
Gets no or very little attention from mass media
Coverage by educational publications poor/missed
Relatively little research compared to other NPS
3 TYPES OF NPS BASED ON SOURCE

Synthetic opioids: bromadol
Bromophenyldimethylaminophenylethylcyclohexanol
500 times stronger than morphine:
20 mg morphine / 10 mg heroin = 0.04 mg bromadol [40 mcg]
Short-term effects include analgesia, sedation, euphoria,
constipation, itching & respiratory depression
Longer-term effects include tolerance and dependence

Herbal products containing synthetic cannabinoids
Usually sold as
herbal preparations
containing inert
herbal material (leaf
etc.) saturated with
synthetic cannabinoids (SCs) & other
drugs. The pure SC
powder can also be
obtained online.
New legal synthetic cannabinoids
Latest batch of legal synthetic cannabinoids sold
online include: 5F-PB22, AKB-48F, STS-135 & BB-22:
from £15 a gram to £3,000 a kg – e.g.

“Acute Kidney Injury Associated with
Synthetic Cannabinoid (SC) Use”
In 2012, Wyoming Department of Health investigated 16 cases
of Acute Kidney Injury (AKI) following SC use, across 6 states.
5 of the 16 patients had used a new SC called XLR-11
Also: SCs are 2 to 3 times more likely than cannabis to produce
sympathomimetic effects (tachycardia, hypertension), and 5
times more likely to produce hallucinations – with an
increased risk of seizures.

3. Legal responses to NPS
Misuse of Drugs Act amendments (see Appendices)
Temporary Class Drug Orders - ban trafficking for 1 year
while ACMD review (max 14 years prison)
> methoxetamine (made class B, 2013)
> June 2013: 5APB & 6APB (Benzo Fury) & NBOMe
Importation bans: 2DPMP, phenazepam (class C, 2012)
Intoxicating Substances Supply Act 1985 (2008-11: 0)
Trade/consumer legislation
Anti-social Behaviour, Crime & Policing Bill 2013
Response of NPS marketers to NPS bans
Continuing to sell banned NPS in countries which have
not yet banned them
‘Tweaking’ banned chemical to produce new legal
version with similar effects
Producing new NPS in unbanned groups
Banned NPS move into illicit drug market, usually with
rise in price & adulterants and fall in purity, eg.
mephedrone banned in 2010 but still 5th most
popular last-year drug for 16-24s in 2012/13 BCS
(after cannabis, nitrous oxide, cocaine and ecstasy)
4. Recent research and
notable studies
New Musical Express Drugs Survey – October 2013
Sample: 5,295 respondents: 63% male, 56% in FT education,
55% 18-24 years (20% U-18)
Lifetime drug use: 78% - 4 in 10 had tried legal highs
Last-year drug use: 74%: legal highs 2.6%, mephedrone 1.1 %
First drug used: legal highs 1.6%, mephedrone 1.2%
Attitudes: 54% believed legal highs should not be banned
Global Drug Survey 2013
Online survey advertised in Mixmag, Guardian & Gay
Times 2012, n = 22,000 (80% aged 18-30)
NPS/Legal Highs – 12% had ever used
Unknown drugs – 14% had used a drug at a party/club
without knowing what it was
Bought drugs online: 22%
Past-month use in UK (n = 7,000+)
Nitrous oxide
26.9%
Mephedrone
13.8%
Poppers
13.6%
NPS obtained from internet, UK, late 2011
A total of 22 ‘legal high’ products were purchased from 5
different internet sites in late 2011, and each substance was
screened to determine its active ingredients.
Six products - 4 sold as Benzo Fury & 2 as NRG3 - contained 6APB; three contained MDAI; three contained 5-IAI; three
contained methoxetamine; three contained benzocaine;
two (labelled NRG2) contained cathinones, including the
banned mephedrone; and two contained MPA.
Overall, 23% did not contain the listed active ingredients

The NPS are mutating…
Many new NPS identified in Japan in 2012, including a product
containing both URB-754* (inhibitor of an endo-cannabinoid
deactivating enzyme) & 4-Me-MABP (cathinone derivative)
Also, a 3rd unknown compound - N,5-dimethyl-N-(1-oxo-1-(ptolyl)butan-2-yl)-2-(N′-(p-tolyl)ureido)benzamide) – was also
found in the product, and deduced to be an unexpected
reaction between URB-754 and 4-Me-MABP.

Deaths from legal highs in 2012
An average of:
 one death per week in England & Wales
 One death every 3 days in Scotland
Given differences in population size, this means
that the annual mortality rate for legal highs is
three times higher in Scotland (about 1 in
300,000) compared with England & Wales
(about 1 in a million)
5. Conclusions
NPS are a ‘game-changer’ - they have:
> hugely expanded the number of psychoactive drugs
> sidestepped drug-related laws (legal loophole), and
banned NPS are rapidly replaced by more legal NPS
> introduced new drug-related risks and harms;
> caught many drug services unprepared/untrained
> AND they require a harm-reduction approach more
than a recovery approach – but the UK drug
strategy’s primary aim is recovery
Legal high users = guinea pigs

What should we do next?
Take an evidence-based approach
Take a principled approach: theory & models – not
common-sense or counter-productive bans
Cross-national/regional comparisons: especially New
Zealand – Psychoactive Substances Act 2013
Take a harm-reduction approach based on categories
of NPS - stimulant, sedative, hallucinogen etc. – as
well as the effects/harms of specific substances
Involve NPS users: representation, participation
NPS/legal high use
interventions: need
consultation with
and representation
of NPS users on
policy-making and
drug service groups
