Use of psychoactive substances in students at a public university

Introduction: The use of psychoactive substances by the student population has been the object of various studies in Brazil. Objective: To determine the prevalence of substance use among students. Methods: Quantitative study with a closed questionnaire based on standardized assessment instruments was developed. It consists of questions related to types of psychoactive substance use, abuse, frequency and duration of use, self-criticism regarding the use, consequences of use in relation to health, and misdemeanors committed under the influence of psychoactive substances. The sample included the participation of 268 students. A total of 183 (68.3%) questionnaires were analyzed, and only those with positive result for substance abuse at some point in life, the remainder, 85 (31%) questionnaires, had negative responses to psychoactive substances. Results: Students’ responses to the two years surveyed indicated that the first psychoactive substance used was alcohol (77.9%), followed by tobacco use (10.9%), and marijuana (7.6%). Of the students surveyed, 145 (79.2%) answered that still make use of psychoactive substances, and the current frequency of use varies from one or more times per week. When asked about the possibility of being or becoming drug addicts, 169 (92.3%) responded that they are not or will not become dependent. Conclusion: The results indicate the high rate of substance use among college students surveyed, and point to their contradiction to consider such psychoactive substances harmful to their health.

First use of multiple substances: Identification of meaningful patterns

Context: Understanding the process through which adolescents and young adults are trying legal and illegal substances is a crucial point for the development of tailored prevention and treatment programs. However, patterns of substance first use can be very complex when multiple substances are considered, requiring reduction into a few meaningful number of categories. Data: We used data from a survey on adolescent and young adult health conducted in 2002 in Switzerland. Answers from 2212 subjects aged 19 and 20 were included. The first consumption ever of 10 substances (tobacco, cannabis, medicine to get high, sniff (volatile substances, and inhalants), ecstasy, GHB, LSD, cocaine, methadone, and heroin) was considered for a grand total of 516 different patterns. Methods: In a first step, automatic clustering was used to decrease the number of patterns to 50. Then, two groups of substance use experts, three social field workers, and three toxicologists and health professionals, were asked to reduce them into a maximum of 10 meaningful categories. Results: Classifications obtained through our methodology are of practical interest by revealing associations invisible to purely automatic algorithms. The article includes a detailed analysis of both final classifications, and a discussion on the advantages and limitations of our approach.

Family Characterization of Young Experimental Consumers of Psychoactive Substances Seen in the Toxicology Department at Colsubsidio

This investigation characterized families of adolescents experimenting with psychoactive substances (PAS) consumption. Materials and methods: For this purpose, a qualitative study with a hermeneutical emphasis was conducted among a population of adolescents between the ages of 12 and 17 who have experimented with PAS. Semi-structured interviews were conducted with patients and their families employing a flexible protocol of 14 categories. Results: The findings showed low levels of family cohesion and sense of family identity, inconsistency between educational patterns followed by the parents, as well as deficient parental support. Similarly, the findings indicate significant peer influence during the first stages of consumption of illegal substances. In this regard, the findings suggest that more than providing physical satisfaction, consumption represents a form of acquiring prestige and social position while granting a sensation of psychological, emotional and social well-being. Conclusions: Parental influence was also found considerable in regarding the consumption of legal PAS, like alcohol and tobacco. The study identified as a high-priority need to promote and incorporate communication and conflict resolution skills within the family dynamics by means of prevention and monitoring programs. Those skills and programs would be aimed at providing parents of adolescents experimenting with PAS consumption with new educational tools to orientate new raising guidelines so as to respond appropriately to the problems identified in this study.

ADOLESCENCE AND DRUG USE THROUGH THE LENS OF PSYCHOANALYSIS: SUFFERING AND ECSTASY IN THE PASSAGE

ADOLESCENCE AND DRUG USE THROUGH THE LENS OF PSYCHOANALYSIS: SUFFERING AND ECSTASY IN THE PASSAGE The purpose of this study is to reflect upon the psychological factors of adolescent drug addiction according to a psychoanalytic perspective. First we consider adolescence as a social-historical category and then we discuss the psychoanalytic understanding of the adolescent transition. This theoretical path builds the approach that considers drug use as a phenomenon that serves as a passage ritual to contemporary adolescence. This phenomenon is modulated by the drive organization, which determines how the individual will take ownership of the use of psychoactive substances. We conclude that the substance use may function as a buffer-object, activated to deal with the structural fragility of the contemporary affective bonds.

The relationship between subjective experiences during first use of tobacco and cannabis and the effect of the substance experienced first.

INTRODUCTION: We examined the positive and negative subjective feelings associated with initial tobacco and cannabis use as well as the role of these experiences in regular use. Additionally, we investigated the effect of the first substance experienced on initial subjective experiences and later regular use. METHODS: Baseline data from a representative sample of young Swiss men were obtained from an ongoing Cohort Study on Substance Use Risk Factors, which includes 2,321 lifetime tobacco and cannabis users. We assessed the age of first tobacco and cannabis use along with the subjective experiences associated with initial use. Additionally, subjective experiences related to regular use of both substances were analyzed. RESULTS: The initial subjective experiences were divided into positive and negative for each substance, and we found that the feelings associated with first use of tobacco and cannabis were similar. Moreover, the participants who used cannabis before tobacco reported fewer negative experiences associated with first tobacco use, whereas the participants who initially used tobacco reported more negative experiences related to first cannabis use. Also, we identified that regular use was encouraged by positive experiences and that negative experiences were more adverse for regular use of cannabis compared with tobacco. CONCLUSIONS: Taken together, these results indicate that similar subjective experiences were associated with the first use of tobacco and cannabis. Also, the use of cannabis before tobacco, which occurred in only a minority of users, had the potential to enhance the effects of initial tobacco use.

Consommation de substances psychoactives, motivation et ouverture envers l'intervention des adolescents placés en centre de réadaptation

La consommation des jeunes placés dans les centres jeunesse du Québec est bien documentée, mais leurs motivations à consommer, à changer ou à parler de leur consommation avec un intervenant demeurent inconnues. Par ailleurs, très peu de chercheurs se sont intéressés aux particularités du processus de changement à l’adolescence et encore moins à ce processus dans un contexte d’autorité. Pour ces raisons, la présente recherche donne la parole aux jeunes afin de mieux comprendre leur usage de substances psychoactives, leur désir éventuel de réduire ou d’arrêter leur consommation, leur ouverture à réfléchir ou à discuter de leur consommation et leur ouverture envers les interventions disponibles. Basés sur une collecte de données qualitatives composée de 27 entrevues avec les jeunes hébergés au Centre jeunesse de Montréal et de huit mois d’observations participantes dans les unités de vie, les résultats indiquent que la majorité des adolescents interviewés disent consommer diverses substances psychoactives pour lesquelles ils identifient différentes sources de motivation, autant à consommer qu’à changer leur consommation. De plus, ces sources de motivation identifiées sont plus ou moins associées au contexte d’autorité dans lequel les jeunes sont placés. Ainsi, si certains jeunes estiment que la possibilité de changement est facilitée par l’environnement contrôlé du Centre jeunesse, pour d’autres, les contraintes de ce milieu de vie ne semblent pas avoir d’impact sur leur motivation. Par ailleurs, les jeunes démontrent différents degrés d’ouverture envers les interventions disponibles et envers les éducateurs qui les côtoient. En général, les approches compréhensives et moins autoritaires semblent encourager un certain investissement de la relation entre jeunes et éducateurs et peuvent potentiellement faciliter l’établissement d’une relation d’aide et le changement de comportement. En utilisant le cadre théorique proposé, une combinaison du Modèle transthéortique du changement et de la Théorie de l’auto-détermination, il apparaît limité de considérer les jeunes en difficulté comme étant motivés ou non motivés à changer leur consommation. Les analyses démontrent que les perceptions de la nécessité ou des possibilités d’amorcer un processus de changement varient beaucoup d’un jeune à l’autre. Ainsi, l’approche choisie pour intervenir auprès des jeunes en difficulté devrait prendre en considération les nuances et la dynamique des motivations afin de mieux adapter les services offerts et de mieux comprendre les raisons associées au succès et à l’échec de certaines interventions et intervenants vis-à-vis de certains adolescents. En outre, afin de favoriser une perception positive du « placement » et pour que les jeunes le voient comme une « opportunité de changement », il apparaît important d’examiner la fréquence et l’intensité des interventions contraignantes appliquées dans les centres de réadaptation. Finalement, il importe de mentionner que les conclusions de cette étude exploratoire ne permettent d’établir des relations causales entre l’approche choisie par l’intervenant, la motivation à changer et l’ouverture des jeunes. Cependant, les données obtenues permettent d’analyser en profondeur les représentations que les jeunes ont des relations entre ces trois éléments.

Applying a quality use of medicines framework to using essential oils in nursing practice

Nurses are increasingly incorporating complementary therapies into their practices. Aromatherapy is one of the most popular therapies. The basis of aromatherapy is essential oils, which are chemically active substances with a long history of safe traditional use and a growing evidence base to support their use in nursing care. In Australia, essential oils are classified and regulated under the same policies as conventional medicines such as the National Medicines Policy and the Quality Use of Medicines (QUM) framework applies. QUM is a framework for selecting and using medicines safely and effectively if medicines are indicated. The key elements of QUM are a systems-based approach to using medicines based on relevant evidence, partnerships, and informed client consent. Clients are placed at the centre of a QUM medication management process, which is consistent with holistic care. Applying a QUM approach to essential oil use, Quality Use of Essential Oils (QUEO), involves developing effective systems for managing essential oils from an holistic perspective that includes structured assessment and diagnostic processes to enable effective essential oil prescribing and outcome monitoring. In a QUEO approach, essential oils are integrated into the client's overall medication regimen and care plan rather than being used as ‘add-ons’. Adopting QUEO is consistent with the current national focus on the quality use of therapeutic substances, increases the profile of aromatherapy in nursing care and provides important information to guide future aromatherapy practices.

Prescribing of Psychoactive Drugs for Older People in Nursing Homes: An Analysis of Treatment Culture

Background There is increasing interest in how culture may affect the quality of healthcare services, and previous research has shown that ‘treatment culture’—of which there are three categories (resident centred, ambiguous and traditional)—in a nursing home may influence prescribing of psychoactive medications. Objective The objective of this study was to explore and understand treatment culture in prescribing of psychoactive medications for older people with dementia in nursing homes. Method Six nursing homes—two from each treatment culture category—participated in this study. Qualitative data were collected through semi-structured interviews with nursing home staff and general practitioners (GPs), which sought to determine participants’ views on prescribing and administration of psychoactive medication, and their understanding of treatment culture and its potential influence on prescribing of psychoactive drugs. Following verbatim transcription, the data were analysed and themes were identified, facilitated by NVivo and discussion within the research team. Results Interviews took place with five managers, seven nurses, 13 care assistants and two GPs. Four themes emerged: the characteristics of the setting, the characteristics of the individual, relationships and decision making. The characteristics of the setting were exemplified by views of the setting, daily routines and staff training. The characteristics of the individual were demonstrated by views on the personhood of residents and staff attitudes. Relationships varied between staff within and outside the home. These relationships appeared to influence decision making about prescribing of medications. The data analysis found that each home exhibited traits that were indicative of its respective assigned treatment culture. Conclusion Nursing home treatment culture appeared to be influenced by four main themes. Modification of these factors may lead to a shift in culture towards a more flexible, resident-centred culture and a reduction in prescribing and use of psychoactive medication. 

Teleconsultation in sexual and reproductive health for young adults through mobile devices: Experience in Colombia

Background: Sexual risk behaviors associated with poor information on sexuality have contributed to major public health problems in the area of sexual and reproductive health in teenagers and young adults in Colombia. Objective: To measure the perception of changes in sexual and reproductive risk behavior after the use of a teleconsultation service via mobile devices in a sample of young adults. Methods: A before and after observational study was designed, where a mobile application to inquire about sexual and reproductive health was developed. The perception of changes in sexual and reproductive health risk behaviors in a sample of young adults after the use of the application was measured using the validated survey “Family Health International (FHI) – Behavioral Surveillance Survey (BSS) – Survey for Adults between 15 to 40 Years”. Non-probabilistic convenience recruitment was undertaken through the study´s web page. Participants answered the survey online before and after the use of the mobile application for a six month period (intervention). For the inferential analysis, data was divided into three groups (dichotomous data, discrete quantitative data, and ordinal data), to compare the results of the questions between the first and the second survey. For all tests, a confidence interval of 95% was established. For dichotomous data, the Chi-squared test was used. For quantitative data, we used the Student’s t-test, and for ordinal data, the Mann-Whitney-Wilcoxon test. Results: A total of 257 subjects were registered in the study and met the selection criteria. The pre-intervention survey was answered by 232 subjects, and 127 completely answered the post-intervention survey, of which 54.3% did not use the application, leaving an effective population of 58 subjects for analysis. 53% (n=31) were female, and 47% (n=27) were male. The mean age was 21 years, ranging between 18 and 40 years. The differences between the answers on the first and the second survey were not statistically significant. The main risk behaviors identified in the population were homosexual relations, non-use of condoms, sexual relations with non-regular and commercial partners, the use of psychoactive substances, and ignorance about the symptoms of sexually transmitted diseases and HIV transmission. Conclusions: Although there were no differences between the pre- and post-intervention results, the study revealed different risk behaviors among the participating subjects. These findings highlight the importance of promoting educational strategies on this matter and the importance of providing patients with easily accessible tools with reliable health information.

Atividades psiquiátricas no campo dos transtornos devidos ao uso de substâncias psicoativas

There are a large number of institutions, proposals and publications in the field of disorders resulting from the use of psychoactive substances. There is no corresponding progress in results obtained in clinical treatments. Concepts and appropriate points of view are indispensable. The vision of the world drug addicts is not only determined by the biochemical effects of intoxication, but also by the experience they go through, by their own way of living. By accepting such postulate, we may conceptualize the problem, thus benefiting research studies and more efficient treatments. Preventing intoxication, upon the onset of dependence, depends on educational, social, legal and other measures, which can neither be studied nor practiced by medicine.

Uso da morfina no período gestacional e lactação: efeitos sobre o desenvolvimento do sistema nervoso central e comportamento

O uso de substâncias psicoativas é um dos maiores problemas da sociedade moderna, causando transtornos sociais, econômicos e à saúde do usuário. Em 2010, 26,4-36 milhões de pessoas utilizaram analgésicos opióides para fins não-terapêuticos, sendo a frequência de uso nocivo por profissionais de saúde, cinco vezes maior quando comparados a população geral, devido ao acesso facilitado. A prevalência no uso durante a gravidez apresenta taxas que variam de 1% a 21%, representando preocupação na sociedade, uma vez que os efeitos ocasionados no desenvolvimento do feto ainda não estão bem elucidados. O objetivo deste estudo foi avaliar as respostas neurocomportamentais de ratos adultos após exposição crônica à morfina, durante o período intrauterino e lactação. Ratas grávidas receberam durante 42 dias, via subcutânea, morfina 10 mg/kg/dia. A prole foi pesada nos dias D1, D5, D10, D15, D20, D30, D60, e os ensaios comportamentais realizados com a prole aos 2,5 meses de idade, os quais consistiram no modelo do campo aberto, labirinto em cruz elevado, nado forçado e rota-rod. Os resultados demonstraram que a exposição à morfina promoveu redução no ganho de peso da prole após o nascimento e inclusive após o desmame, aumento da locomoção espontânea das fêmeas, bem como aumento do comportamento do tipo ansiogênico e comportamento do tipo depressivo, independente do sexo, porém sem prejuízo motor associado.
