Summary Humans have always used mind-altering drugs. However, in 1961 the
United Nations approved the Single Convention, under which the production, sale or
possession of a number of drugs, including heroin, cocaine, ecstasy and cannabis,
became illegal. The prohibitionist regime was then introduced by most countries
around the world and has substantially remained in place ever since. Some countries,
particularly those in Latin America, have never criminalised the use of cannabis.
A small number of countries have introduced more liberal policies. This article
examines the evidence of the consequences of policy liberalisation and argues that
there is now a clear case for every country to examine its drug policies and to
introduce evidence-based policies with a public health focus.
Declaration of interest None.
Keywords Drug policies; drug control policies; approach to controlled drugs.
Human beings have taken mind altering drugs since the Stone
Age, but the current global war on drugsdates only from
1961. At that time, the addictive qualities of drugs like heroin
and cocaine led the United Nations Member States to
conclude that drastic action had to be taken as they were
concerned with the health and welfare of mankind
1
the
objective of the United Nations Single Convention on
Narcotic Drugs. The assumption at the time was that a drug-
free world could be created if those who produce, sell, possess
or use certain addictive drugs were severely punished.
Currently, in the UK, those arrested for possession of a
controlled drug (e.g. heroin, cocaine, ecstasy or cannabis)
can have a maximum prison sentence of 7 years under the
UK Misuse of Drugs Act 1971. Producers and suppliers can
be put behind bars for a maximum of 14 years.
A policy objective to advance the health and welfare of
mankind is ne if the policy makers know the consequences
of their proposed policies. In fact, instead of advancing the
health and welfare of mankind, the drug laws that followed
the United Nations Convention have led to untold violence
and corruption in the producer countries, drug-related
deaths, the accumulation of wealth worth billions of dollars
by terrorists and violent criminals, the non-availability of
essential pain-relieving medicines in many developing coun-
tries and the emergence of an extremely dangerous online
market for synthetic psychoactive drugs. Of course, none
of these consequences was predicted in 1961. It is not that
the policy makers at that time were bad, they were simply
ignorant of the consequences of their policies.
For political reasons, two of the most dangerous drugs
widely used across the globe alcohol and tobacco were
excluded from the Convention. Although rated as less dan-
gerous than heroin and cocaine on a carefully devised scale
of harm, both these drugs have been rated well above canna-
bis and ecstasy in their potential danger to the individual.

con-
cluded that, In the long run, society will only be at ease with
its drug control policies if they are based on a rational
assessment of the risks associated with the dierent psycho-
active substances and an objective appraisal of the conse-
quences of previous policy changes, rather than on moral
postures, the mistaken assumptions of the past and the acci-
dents of history(p. 259).
This suggests we need an entirely new approach to con-
trolled drugs. The starting point must be a clear denition of
the objectives of drug policy. The All Parliamentary Group
for Drug Policy Reform
4
proposed the following objectives
to the United Nations:
(a) to ensure the adequate availability of essential con-
trolled medicines to those who need them (relevant
to the many developing nations who have minimal
or no access to morphine);
(b) in production and supply countries, to prioritise edu-
cation, community development, infrastructure devel-
opment and employment in vulnerable communities;
(c) in user countries, to minimise addiction and the
harms associated with drug use.
In 1961 there was widespread consensus that a crimina-
lising approach to the sale and use of heroin, cocaine and
cannabis was appropriate, but this is no longer the case
today. Now, even the Global Commission on Drugs Policy
reports that the prohibitionist approach has failed.
5
Arguments for and against drug prohibition in relation to
heroin and cocaine may be more nely balanced, but there
has been a major swing both among scientists and politicians
SPECIAL ARTICLE

toward the view that the illegal status of less harmful drugs,
especially cannabis, does more harm than good.
Considerable concern has been raised concerning the
decriminalisation of cannabis as a result of studies showing
links between skunk(high-potency cannabis) and the onset
of psychosis. An inuential study has shown that people who
use skunk daily are ve times more likely to develop psych-
osis than those who do not.
6
However, the same study
showed that, when the eects of low-potency cannabis
were examined, hash users did not have any increase in
risk of psychotic disorders compared with non-users, irre-
spective of their frequency of use. Further, although it is
now widely accepted that there is a causal relationship
between regular high-potency cannabis users and psychosis,
the possible importance of the eect of confounding factors
makes the signicance of even this nding for drugs policy
unclear. It has been estimated, for example, that 98% of
regular cannabis users will not develop a psychotic disorder.
7
Further, decriminalisation would allow much more eective
control, especially of high-potency cannabis, than is the case
at the present time.
The uncertainty regarding the eects of decriminalisa-
tion can only be resolved by examining the eect of decrimi-
nalising legislation where it is occurring elsewhere in the
world. There are now a number of studies examining the
eects of drug law liberalisation, especially, but not only,
in relation to cannabis. A recent review suggested that liber-
alisation of cannabis laws is associated with a slight increase
in use of cannabis among the young.
8
A cross-national study
of 38 countries conrmed this nding, noting that the
increase was only detectable after 5 years and then mainly
in girls.
9
Further, although adolescent use remains crimina-
lised in US states where marijuana use has been legalised for
adults, decriminalisation has led to decreases in possession
and felony arrests among adolescents as well as reduction
of associated juvenile-justice involvement.
10
It has also
been shown in a 20-country comparison that cannabis law
liberalisation leads to increased help-seeking behaviour for
people with drug problems, an encouraging nding suggest-
ing that if some of the savings made as a result of the discon-
tinuation of prohibition policies were put into increasing
and improving drug services, any negative eects might be
signicantly reduced.
11
It has recently been suggested that positive experience
from cannabis law liberalisation might lead to some coun-
tries looking more critically at their laws relating to other
potentially more dangerous drugs.
12
There is already some
evidence to suggest this might have benecial eects. In
2001, Portugal changed its approach to the possession of
all drugs. The drugs remained illegal, so the policy did not
resolve the problem of illegal drug dealers enriching them-
selves by selling contaminated drugs. However, children
and young people who go through a drug-taking phase do
not end up with a criminal record and can much more easily
give up the habit and progress with their education and
employment the best protections from addiction.
This policy is not softon drug users. If a police ocer
nds a young person with drugs, they will be taken to the
police station and required to hand over the drugs, they
are then referred to a Commission for the Dissuasion of
Drug Addiction or tribunal including a legal, health and a
social work professional. The tribunal will determine
whether the drug possessor is addicted to drugs. If so, they
will be referred for treatment. The treatment becomes the
basis of a contractual agreement between the drug user
and the tribunal. If the drug user breaks the contract, they
could receive an administrative penalty, although this rarely
happens. Importantly this has no implications for their
future employment. A casual user is sent on their way by
the tribunal and strongly told not to continue using the
drug. Portugal invested heavily in prevention, treatment,
harm reduction and social integration services. The combin-
ation of decriminalisation with improved health and social
care services probably account for the good results.
Importantly the policy has been extensively evaluated.
13
Portugal now has levels of drug use well below the national
European average. The numbers sent to the criminal courts
in Portugal fell from more than 14 000 to 50006000 a year
after the policy was introduced. The proportion of oenders
for drug-related oences fell from 44 to 21% between 1999
and 2012. The numbers of addicted children and young peo-
ple has decreased. All the same, critical analysis of studies of
those who claim that the Portuguese drug policy has been a
resounding success or, in contrast, a disastrous failure sug-
gest that the evidence does not support either extreme
view.
14
Switzerland has shown how to replace drug dealers with
heroin treatment services. The services largely cater for poly
drug users. The service has three parts: the drug consump-
tion room (DCR), the heroin clinic and the methadone clinic.
The service providers have an agreement with the police that
anyone approaching the DCR will not be arrested for drug
possession. The DCR is a vital part of the service. A doctor
spends time there each week, treating ulcers and other
health problems, and a social worker is available to help
with housing, nancial and other social issues. Addicted cli-
ents who come in othe street with their illegal drugs are
welcomed and cared for. Over about 3 weeks these two pro-
fessionals encourage the street drug users to come along to
the clinic and have clean heroin in exchange for agreeing
to a demanding contract. These chaotic individuals are
required to hand over their benets in the early stages, to
make sure their rent and bills are paid. They are given
back the money they need for food or other essentials, but
not enough for them to buy drugs.
The constraints are worth it in return for the clean her-
oin as well as the psychological and social care. The Swiss
heroin treatment programme has been rigorously evalu-
ated.
15
The results are impressive. Until they arrived at the
clinic these individuals were committing an average of 80
crimes a month to feed their addiction. After 18 months in
treatment, one third are entirely drug-free and leading nor-
mal lives; a further third are leading their lives within the
law, but still taking some heroin or methadone. The last
third need more time to achieve their objectives. The savings
to the tax payer and the benets to the community from
reduced crime levels are huge. The estimate is that for
every franc spent on this service, two francs are saved for
the taxpayer. The cost of the service per person is 15 000
euros. Not cheap but well worth it.
In the meantime, in England, the Durham Police are
beginning to use the Swiss route for users of all narcotic

drugs and even for low-level drug dealers and trackers.

Their Check Point programme recognises that many who
are arrested for theft motivated by drugs and other less
serious crimes have underlying mental health and social pro-
blems. The programme oers drug-related oenders and
others a 4-month contract. This requires them to engage
with treatment and not to reoend. If they succeed on
their contract then no further criminal justice action is
taken. If successful in rehabilitating drug users and cutting
reoending, this will surely be an important policy across
the country. The government will be funding 10 pilots of
Checkpoint and 25 police forces are wanting to apply to be
involved.
To conclude, an independent review of UK drug policies
is urgently needed. Each drug needs to be individually con-
sidered. Regulation of heroin, for example, needs to be very
dierent from the regulation of cannabis or ecstasy. The
objectives must be to reduce addiction and limit as far as
possible the harms associated with drug use. Drug policy
reform would also dramatically reduce the ill-gotten gains
from the drugs trade of terrorists and violent criminals.
In fact, we need to turn, not just policy about cannabis,
but our whole drugs policy in its head. Opponents of the
legalisation of cannabis, who suggest that this might well
represent a slippery slope leading to the legalisation of
other, currently proscribed drugs are right. But that is
exactly what needs to happen.

Neuropathic pain associated with nucleoside reverse transcriptase inhibitors (NRTIs), therapeutic agents for human immunodeficiency virus (HIV), responds poorly to available drugs. Smoked cannabis was reported to relieve HIV-associated neuropathic pain in clinical trials. Some constituents of cannabis (Cannabis sativa) activate cannabinoid type 1 (CB1) and cannabinoid type 2 (CB2) receptors. However, activation of the CB1 receptor is associated with side effects such as psychosis and physical dependence. Therefore, we investigated the effect of β-caryophyllene (BCP), a CB2-selective phytocannabinoid, in a model of NRTI-induced neuropathic pain. Female BALB/c mice treated with 2′-3′-dideoxycytidine (ddC, zalcitabine), a NRTI, for 5 days developed mechanical allodynia, which was prevented by cotreatment with BCP, minocycline or pentoxifylline. A CB2 receptor antagonist (AM 630), but not a CB1 receptor antagonist (AM 251), antagonized BCP attenuation of established ddC-induced mechanical allodynia. β-Caryophyllene prevented the ddC-induced increase in cytokine (interleukin 1 beta, tumor necrosis factor alpha and interferon gamma) transcripts in the paw skin and brain, as well as the phosphorylation level of Erk1/2 in the brain. In conclusion, BCP prevents NRTI-induced mechanical allodynia, possibly via reducing the inflammatory response, and attenuates mechanical allodynia through CB2 receptor activation. Therefore, BCP could be useful for prevention and treatment of antiretroviral-induced neuropathic pain.

Na podstawie polityki narkotykowej Szwajcarii nabiera się przekonania, że zerowa tolerancja wobec narkotyków i osób od nich uzależnionych wcale nie jest najlepszym kierunkiem postępowania. Ryzyko podjęte przez to państwo i oparcie polityki zwalczania narkotyków i narkomanii na czterech aspektach – redukcji szkód, działaniach policji, odpowiednio wczesnym zapobieganiu sięgania po środki odurzające i leczeniem zaistniałych już uzależnień – doprowadziło do zmniejszenia liczby zgonów spowodowanych zażywaniem narkotyków, poprawy stanu zdrowia osób uzależnionych, a także zmniejszenia przestępczości. Choć przykład Szwajcarii doskonale obrazuje, że restrykcyjne, prohibicyjne podejście do problemu narkotykowego jest niewystarczające, by go skutecznie rozwiązać, w kraju tym wciąż nie uporano się ze wszystkimi trudnościami związanymi z obecnością narkotyków. Problemem dalej aktualnym jest bowiem przestępczość narkotykowa, która choć maleje, nadal pozostaje wyzwaniem dla szwajcarskich polityków, organów ścigania i wymiaru sprawiedliwości. Zasadniczym pytaniem jednak pozostaje, czy przestępczość tego rodzaju jest w ogóle możliwa do całkowitej eliminacji. Wydaje się to niemożliwe, a wynika to chociażby ze specyfiki przestępczości narkotykowej i rynku narkotykowego, które szybko się zmieniają, w obszarze których pojawiają się nowe substancje psychoaktywne, na które zmienia się zapotrzebowanie. Na podkreślenie zasługuje jednak pozytywny wniosek płynący z analizy statystyk kryminalnych szwajcarskiej policji – zauważalne jest bowiem systematyczne zmniejszanie się rozmiarów przestępczości narkotykowej. Należy przy tym przypuszczać, że przestępstwem narkotykowym wymagającym w przyszłości stałego monitorowania i podejmowania działań zwalczających będzie import narkotyków do Szwajcarii, bowiem w przypadku tego zachowania od kilku lat zauważalne jest jego nasilanie się. Niniejsze opracowanie nie wyczerpuje problematyki przestępczości narkotykowej w Szwajcarii, lecz zaledwie rozpoczyna rozważania na ten temat w polskiej debacie prawno-kryminologicznej. Mając na uwadze planowane zmiany władz Szwajcarii w zakresie legalizacji niektórych środków odurzających i dynamikę zmian na rynku narkotykowym, w tym na gruncie przestępczości narkotykowej, należy przedmiotowe zagadnienie monitorować i poddawać dalszym badaniom.

Background: While the impact of changing drug policies on rates of drug use has been investigated, research into how help-seeking behaviour changes as drug policies become more public-health focused is limited. This paper investigates reported changes in confidence to utilise drug services following hypothetical changes in national drug policy among a sample of individuals who report recent illicit drug use. We predict that liberalising national drug policy will increase the propensity for people who take illegal drugs to utilise health services. Methods: The data were drawn from a sample of self-reported responses to the 2014 Global Drug Survey. Respondents were asked if they would be more confident seeking help if each of the following policy changes were made in their country; a) drugs were legalised; b) penalties for possession of small amounts of drugs were reduced to a fine only; c) drugs were legally available through governments outlets. Multiple correspondence analysis and multinomial logistic regression with post-estimation linear hypothesis testing were conducted. Results: Individuals residing in countries with relatively liberal drug policy regimes report their help-seeking behaviour is unlikely to change given the hypothetical policy amendments. Individuals from countries with prohibition-based drug policies reported a far greater propensity for changing their help-seeking behaviour in the event of hypothetical policy amendments, citing reduced fear of criminal sanctions as the major reason. Age and sex differences were also found. Conclusion: The current study demonstrates the capacity for national drug policy reform to influence drug use risk by facilitating or impeding health service engagement among individuals who use illicit substances. We suggest national drug policy requires careful consideration of both prevention goals and the needs of individuals already engaged in illicit substance use; more liberal drug policies may actually encourage the adoption of harm reduction strategies such as health service engagement.

Purpose of review: Policies that limit young people's access to cannabis may reduce early onset of use and minimize health-related harm. This review article provides an update of recent research examining the influence of the cannabis policy frameworks on the use of cannabis by young people. Recent findings: There are significant concerns that ongoing policy changes in favour of legalization will increase the uptake of cannabis by young people. Evidence to support a causal effect of cannabis policy changes on increased uptake by young people is lacking; more time may be needed to assess the impact because the policies are still evolving. Policy changes in favour of legalization were associated with reduced risk perception although this may be a cause or consequence. The need to situate the impact of these policies in the context of specific policy features, social norms and perceptions about cannabis has been highlighted. Summary: A more nuanced understanding of the impact of the legal status of cannabis on young people is needed to build evidence for future policy options. The impact of these policies may not be immediately apparent but limiting young people's access to cannabis must be prioritized during policy deliberations.

Aims: To assess the associations between types of cannabis control policies at country level and prevalence of adolescent cannabis use. Setting, participants and design: Multilevel logistic regressions were performed on 172,894 adolescents 15 year of age who participated in the 2001/2002, 2005/2006, or 2009/2010 cross-sectional Health Behaviour in School-Aged Children (HBSC) survey in 38 European and North American countries. Measures: Self-reported cannabis use status was classified into ever use in life time, use in past year, and regular use. Country-level cannabis control policies were categorized into a dichotomous measure (whether or not liberalized) as well as 4 detailed types (full prohibition, depenalization, decriminalization, and partial prohibition). Control variables included individual-level sociodemographic characteristics and country-level economic characteristics. Findings: Considerable intra-class correlations (.15-.19) were found at country level. With respect to the dichotomized cannabis control policy, adolescents were more likely to ever use cannabis (odds ratio (OR) = 1.10, p = .001), use in past year (OR = 1.09, p = .007), and use regularly (OR = 1.26, p = .004). Although boys were substantially more likely to use cannabis, the correlation between cannabis liberalization and cannabis use was smaller in boys than in girls. With respect to detailed types of policies, depenalization was associated with higher odds of past-year use (OR = 1.14, p = .013) and regular use (OR = 1.23, p = .038), and partial prohibition was associated with higher odds of regular use (OR = 2.39, p = .016). The correlation between cannabis liberalization and regular use was only significant after the policy had been introduced for more than 5 years. Conclusions: Cannabis liberalization with depenalization and partial prohibition policies was associated with higher levels of regular cannabis use among adolescents. The correlations were heterogeneous between genders and between short- and long-terms.

Background: The risk of individuals having adverse effects from drug use (eg, alcohol) generally depends on the frequency of use and potency of the drug used. We aimed to investigate how frequent use of skunk-like (high-potency) cannabis in south London affected the association between cannabis and psychotic disorders. Methods: We applied adjusted logistic regression models to data from patients aged 18-65 years presenting to South London and Maudsley NHS Foundation Trust with first-episode psychosis and population controls recruited from the same area of south London (UK) to estimate the effect of the frequency of use, and type of cannabis used on the risk of psychotic disorders. We then calculated the proportion of new cases of psychosis attributable to different types of cannabis use in south London. Findings: Between May 1, 2005, and May 31, 2011, we obtained data from 410 patients with first-episode psychosis and 370 population controls. The risk of individuals having a psychotic disorder showed a roughly three-times increase in users of skunk-like cannabis compared with those who never used cannabis (adjusted odds ratio [OR] 2·92, 95% CI 1·52-3·45, p=0·001). Use of skunk-like cannabis every day conferred the highest risk of psychotic disorders compared with no use of cannabis (adjusted OR 5·4, 95% CI 2·81-11·31, p=0·002). The population attributable fraction of first-episode psychosis for skunk use for our geographical area was 24% (95% CI 17-31), possibly because of the high prevalence of use of high-potency cannabis (218 [53%] of 410 patients) in our study. Interpretation: The ready availability of high potency cannabis in south London might have resulted in a greater proportion of first onset psychosis cases being attributed to cannabis use than in previous studies.

The issue of decriminalizing illicit drugs is hotly debated, but is rarely subject to evidence-based analysis. This paper examines the case of Portugal, a nation that decriminalized the use and possession of all illicit drugs on 1 July 2001. Drawing upon independent evaluations and interviews conducted with 13 key stakeholders in 2007 and 2009, it critically analyses the criminal justice and health impacts against trends from neighbouring Spain and Italy. It concludes that contrary to predictions, the Portuguese decriminalization did not lead to major increases in drug use. Indeed, evidence indicates reductions in problematic use, drug-related harms and criminal justice overcrowding. The article discusses these developments in the context of drug law debates and criminological discussions on late modern governance.

In 2017, the annual prevalence of marijuana use rose to 24% among 8th to 12th graders, despite decreases in rates of other illicit substance use.1 This is of concern, as increasing use is coupled with declining perception of harm among adolescents,1 increasing potency of cannabis,2 ease of adolescents' access to marijuana,1 and progressive medicalization and legalization of marijuana. Exposure to high levels of Δ-9-tetrahydrocannabinol through cannabis use triggers repeated activation of the endogenous mesolimbic dopaminergic system, desensitization, and progressive enhancement of acquired susceptibility to psychosis.3.

Cannabis policies are changing in some countries. This may have consequences that extend beyond cannabis-specific outcomes, such as an impact on the consumption patterns of other substances. Changes in cannabis policies may also influence policy responses to other drugs, as countries re-assess the balance between law enforcement and public health objectives. If this happens, it could have important health and social consequences, especially in those countries where a 'war on drugs' policy perspective has inhibited investment in evidence based responses in areas such as treatment and harm reduction. The burden of disease associated with opioid use for example is large and this is an area in which treatment and harm reduction have been shown to deliver benefits. Thus if the changes in cannabis policies result in a greater willingness to invest in effective interventions for other drugs, the potential net health gains could be considerable. On the other hand, if cannabis policy changes are associated with an increase in health risk behaviours, such as driving under the influence or increased use of harmful substances such as tobacco, then significant increased health costs could result. To date most attention has been focused on recent cannabis sales liberalisation in the Americas, but experiences from elsewhere are also informative. In Europe, for example, moves towards decriminalisation of drug possession are resulting in lower rates of incarceration and arguably have reduced barriers to treatment uptake. Robust monitoring and assessment of the impact of these different policy changes is crucial to evaluating and understanding their results. It is important that such monitoring is international in scope, is not limited to issues around the use of cannabis only, and considers the interactions that may exist between cannabis policies and the approaches taken to other substances.

Associations between cannabis use and psychotic outcomes are consistently reported, but establishing causality from observational designs can be problematic. We review the evidence from longitudinal studies that have examined this relationship and discuss the epidemiologic evidence for and against interpreting the findings as causal. We also review the evidence identifying groups at particularly high risk of developing psychosis from using cannabis. Overall, evidence from epidemiologic studies provides strong enough evidence to warrant a public health message that cannabis use can increase the risk of psychotic disorders. However, further studies are required to determine the magnitude of this effect, to determine the effect of different strains of cannabis on risk, and to identify high-risk groups particularly susceptible to the effects of cannabis on psychosis. We also discuss complementary epidemiologic methods that can help address these questions.

In this Harm Reduction Digest two observers and scholars of the 2001 Portuguese drug policy reform consider divergent accounts of the reform which viewed it as a ‘resounding success’ or a ‘disastrous failure’. Acknowledging from their own experience the inherent difficulties in studying drug law reform, Caitlin Hughes and Alex Stevens take the central competing claims of the protagonists and consider them against the available data. They remind us of the way all sides of the drug policy debates call upon and alternatively use or misuse ‘evidence’ to feed into discussions of the worth, efficacy and desirability of different illicit drug policies. In doing so they provide pause for thought for those of us who operate as drug policy researchers and drug policy advocates. Simon Lenton Co-editor, Harm Reduction Digest
