syndrome ago. It has a history of cannabis, cocaine and alcohol since
he was thirteen and remains abstinent for more than six months
ago. Differential diagnosis arises between amotivational toxic syn-
drome, reactive depressive symptoms to the disease and negative
symptoms for chronic psychotic process. Finally diagnosed with
paranoid schizophrenia and is included in the program of first psy-
chotic episodes.
Today the productive symptoms disappeared and remain negative
though with less intensity achieving an improvement in overall
activity.
Conclusions Consumption of toxic influences the development of
a chronic psychotic process that may appear years later, becom-
ing a etiological and maintainer factor, not only if its consumption
continue, but other effects that occur long term amotivational syn-
drome and worsening prognosis.

Introduction Traditionally, cannabis is associated with
antiemetic action after acute consumption. However, in 2004
the cannabinoid hyperemesis as paradoxical effect of chronic
users, after years of exposure described.
Objectives Description of the cannabinoid hyperemesis.
Method OLOGYA case is presented.
Results Clinical case of a woman who repeatedly comes to the
emergency service because of abdominal, nausea and vomiting
pain.
This is cyclical and hardly controllable. The gastroenterology ser-
vice studied in depth with negative results. She was followed up by
mental health borderline personality disorder and she consumed
cannabis at an early age, 20–30 joints daily.
When she reaches abstinence in short periods, ceases digestive dis-
comfort. However, aprece digestive symptoms with each relapse.
The present case showed improvement with cessation of cannabis
so it probably was the cannabinoid hyperemesis syndrome.
Conclusions The cannabinoid hyperemesis is characterized by
recurrent episodes of nausea, vomiting, abdominal pain, and
chronic cannabis use. Temporary relief is achieved with hot baths.
Ceases when abstinence is achieved. It is a clinical entity that does
not have much information and requires further study.

Introduction Legal and illegal drugs can cause psychotic symp-
toms, in cocaine-dependent patients the prevalence of these
symptoms may reach 86% (Vorspan, 2012). It is estimated that
13–32% of cocaine-dependent patients have kinaesthetic halluci-
nations (Siegel, 1978; Mahoney, 2008; Roncero, 2012).
Objectives To compare the prevalence of substance-induced psy-
chotic symptoms and compare the use of welfare/social resources
and social adjustment among cocaine-dependent patients (CD) and
other substances dependences (OtherD).
Methods Two hundred and six patients seeking treatment at
the Addictions and Dual Diagnosis Unit of the Vall d’Hebron.
Patients were assessed by ad hoc questionnaire designed to collect
demographic data and psychotic symptoms associated with con-
sumption, a record of the care/social resources used by the patient
and the scale of social adaptation (SASS). A descriptive and bivariate
analysis of the data was performed.
Results CD were 47.1% vs. 52.9% OtherD (66.1% alcohol, 17.4%
cannabis, 8.3% opioid, 8.3% benzodiazepines/other drugs). Of
cocaine dependent-patients, 65.6% present psychotic symptoms vs.
32.1% for the OtherD. Different exhibiting psychotic symptoms are:
self-referential (69.7% vs. 30.7%), delusions of persecution (43.4%
vs. 12.2%), hallucinations (49.4% vs. 14.3%), auditory hallucinations
(43.5% vs. 11.4%), visual hallucinations (30.4% vs. 5.7%) and kinaes-
thetic hallucinations (7.2% vs. 2.9%).
Cocaine-dependent patients significantly use more health care
resources in reference addiction unit (76.3% vs. 62.4%, P:.035)
and infectious diseases (22.7% vs. 5.5%, P:.000) and justice-related
(50.5% vs. 26 resources 0.6%; P:1.001) and less resources andmental
health (25.8% vs. 43.1%; P:.013).
Regarding social adaptation, no differences were found in the SASS.
Kinaesthetic hallucinations do not appear to be related to a greater
use of resources and in social adaptation.
