The dependency of psychoactive substances whether licit or illicit, among adolescents is a topic that has aroused much discussion today. One of the psychoactive substance that has caught the attention of authorities and experts, its potential dependence, increasing the number of addicts and speed with which triggers the human degeneration is the crack (a derivative of cocaine - Erythroxylon coca), used via the smoked administration. Understanding the phenomenon of increasing their use requires an analysis of the concepts of addiction throughout history, current research encompassing scientific findings in epidemiology and statistics involving several types of pharmacological substances, and especially the analysis of data related specifically to crack the focus of our theme. In order to contribute to ongoing discussions and offer possible alternatives for effective intervention, especially in schools, we conducted a survey that sought to find evidence of a possible relationship between crack use and moral reasoning. Since our work specifically theoretical nature, we use to reach our goals, assumptions, two researchers in the concept of human morality: Jean Piaget (1994) and Lawrence Kohlberg (1992) both traveling within the proposed cognitive-evolutionary human development. For an understanding of the proposals of these two researchers, we use research to (Lepre, 2005), as guiding thesis of this work. The results presented indicate that adolescents who use crack are very close to a level of moral reasoning pre-conventional and conventional, although it is important to state that more accurate results require further research on the subject, including those involving field research. Yet we can conclude that prevention must go through a dialogue that privileges the moral education as possible means of effective intervention against the use of crack, allowing the construction of autonomy...

This dissertation shows a comparison between practices related to the body, to identities and to the health of young drug takers of synthetic and manipulated psychoactive substances living in Fortaleza. Through ethnographic accompaniment of parties and two social nets of young people I was able to verify the differences and similarities that make these addicted singular and plural in their notion of ethos and world vision. Notions of being hippie/alternative and being punk are present between these nets. Because their use and circulation are developed in environments usually distinct, it is possible to trace singular aspects between the nets and its actions. In parallel, on the attempt to build a triangulated data, I had information related to youth and drugs in local media and in governmental institutions bound to health mental and city security policies. With this junction of data I present a perspective to questions evolving formal and informal important controls to the conduction of their lives and identities. I present this as a sequel to well developed studies in Brasil about youth in interface to drug use, although still not very explored in the state of Ceará.

O estudo da dependência de substâncias psicoativas apresentou grandes avanços conceituais nas últimas décadas. A evolução dos conceitos foi paralela às evidências científicas que têm revelado os aspectos comportamentais e os mecanismos neurais envolvidos nesse fenômeno. Contudo, um grande desafio que permanece na pesquisa sobre a dependência de substâncias psicoativas é a identificação de quais fatores são responsáveis pela transição do uso controlado para o uso compulsivo. Está demonstrado que muitas variáveis interagem para influenciar a probabilidade de que qualquer indivíduo inicie o uso abusivo de substâncias psicoativas ou se torne dependente. Nos últimos anos, o estresse tem sido destacado como um fator importante na iniciação, manutenção e recaída da utilização de substâncias psicoativas. Neste trabalho analisamos os conceitos e teorias da farmacodependência e as principais evidências comportamentais pré-clínicas que demonstram a relação entre estresse e a vulnerabilidade ao abuso e dependência de psicoestimulantes.

Foram analisadas as manifestações neurológicas em 93 doentes com suspeita de intoxicação exógena. A detecção das substancias tóxicas foi realizada no sangue, urina e líquido cefalorraqueano. Verificou-se nítido predomínio do comprometimento do sistema nervoso central em relação ao periférico e aparente tropismo de herbicidas e organofosforados para o sistema nervoso central, comparando-se o comportamento dos metais pesados e organoclorados. São analisados os prováveis mecanismos de ação dessas substancias no sistema nervoso e são apresentados os sinais e/ou sintomas que foram observados.

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.
