Introduction Due to the continuous search for new, legal, less
expensive, and more powerful highs by drug users, the synthesis
of novel cathinone derivatives has become a fruitful industry, lead-
ing to a fast emergence of new alternative substances every year.
Methylone (3,4-methylenedioxy-N-methylcathinone) is one of the
substances that rapidly emerged as the main ingredient of “bath
salts”, becoming readily accessible on the Internet. This fact has
raised concerns about its potential harmfulness.
Objectives The aimof the present study is to analyze the presence
of methylone in samples delivered to energy control from 2014 to
2015 in Spain.
Methods A total of 8324 sampleswere assessed from June 2014 to
May 2015. Only those samples acquired asmethylonewere studied.
They were analyzed by energy control, a Spanish harm reduction
NGO that offers the possibility of analyzing the substances that
users report. Analysis was done by gas chromatography-mass spec-
trometry.
Results Ten users reported to have acquired methylone (0.12%).
The most used source for acquiring it was the Internet (60%). Other
sources included a friend or relative (10%), home-delivered (10%)
or undetermined (20%). There was no peak of consume as 50% were
acquired in 2014 and 50% in 2015.
Discussion According to the results, the presence of methylone
in our samples is extremely low. Therefore, despite the fact that
methylone monitorization is ought to be carried out, this substance
is not expected to be an emerging issue concerning Public Health
and no further clinical research should be done.

Introduction Portuguese young adults (15–34 years old) were
more frequent engaged in substance abuse (1.2%) than the gen-
eral population, according to the Portuguese substance use annual
report (2014). Alcohol was the most frequent substance use on
youth adults. Cannabis was the most frequent illicit substance used
(23.9% of users were considered dependent), with higher preva-
lence than previously reported. LSD (0.4%) use was also higher
among young adults than in previous studies. Cocaine (0.4%), hero-
ine/opiates (0.4%), ecstasy (0.3%), and hallucinogenic mushrooms
(1.1%) had their consumption lowered among young adults.
Objectives/aims To characterize a population of young adult psy-
chiatric outpatients, regarding substance use and associated risk.
Methods Socio-demographic characterization of our young adult
unit outpatient users between 1st January 2015–31st July 2016.
Substance use was assessed with the Portuguese version of
Alcohol, Smoking and Substance Involvement Screening Test
(ASSIST).
Results A total of 255 outpatients were observed during the
timeframe; 58 outpatients were assessed with ASSIST: 44 females
(75.9%) and 14 males (24.1%), aged between 16–33 years old
(average: 20.95; median: 19.50). For tobacco, 3.5% had high
risk, 37.9% moderate risk and 58.6% low risk; 22.4% had moder-
ate risk of alcohol, 13.8% moderate risk of cannabis, and 20.7%
moderate risk of tranquilizers. For others substances (cocaine,
stimulants, inhalants, hallucinogens, and opiates) the risk was
low.
Conclusions In our sample, alcohol and cannabis use had the
highest risk, as reported in the National Annual Report; however,
we observed a moderate risk for tranquilizers use. In future care
planning, youth mental health should address tobacco and alcohol
abstinence, and preventive measures regarding anxiolytics should
be undertaken, such as banning sale without medical prescription.

Comparative examination of the
differences between cannabis
psychosis and methamphetamine
psychosis in a psychological state
A. Oda
National Hospital Organaization, Simofusa Psychiatric Center,
Psychiatry, Chiba, Japan
Background With the rapid and intensive spread of marihuana
abuse among youth, Japanese society is focusing on law enforce-
ment against drug abusers. In 2016, a mass killing allegedly
committed by a marihuana abuser was reported in Japan.
Objectives To consider that common recognition of the diverse
process and potential risks of cannabis psychosis should be shared
among psychiatrists.
Aims Elicit differences between cannabis psychosis and
methamphetamine psychosis, and determine whether specific
guidelines for treatment of cannabis psychosis are required.
Method Intensive retrospective review of distinctive metham-
phetamine and cannabis psychosis through case studies in our
hospital.
Result Major symptoms of methamphetamine psychosis include
auditory hallucination and paranoia, however recovery is achieved
soon after undertaking treatment. In cannabis psychosis, distinctive
features are megalomania and by a pseud-enlightenment expe-
rience of supernatural existence, abusers stick to an unrealistic
self-estimate of omnipotent, which leads them to refuse the fading
away of this feeling and repeat abuse.
Conclusion Psychological substances have strong suggestibil-
ity so abusers’ symptoms are easily modified by their mental
state. Involvement of syndicate or perception of illegality reflects
abusers’ drastic symptoms, but after dehospitalisation, recur-
rences are relatively fewer. Cannabis, however, grows wild and
is admitted legally in some countries, so abusers lack awareness
of guilt by mistaken perception of omnipotence and unrealistic
optimism. Due to addiction and depersonalization, they rather
enjoy gaining contact with supernatural power and fall into
social withdrawal and are implicated to social problems. Con-
sidering the difficulty of rehabilitating and returning abusers to
the community, we should not disregard the risks of cannabis
abuse.
