Drug consumption and perception among Latin American immigrants

The aim of this study is to obtain information about drug consumption, leisure activities and knowledge of community services among Spanish-speaking immigrants to prevent drug abuse in this population. Quantitative methodology was used. The field work of this study has two phases: in the first stage (2003), a survey of social perception of drugs was administered to 147 subjects. During the second stage (2004), 610 surveys were administered. Data were analysed by bivariate analysis. Usual consumption of alcohol was 40.1%, usual consumption of tobacco was 31.3%, and usual consumption of cannabis was 3.4%. Drug users considered that the main reason for drug consumption was "to have fun" (p<.03). There is a relationship between leisure time and drug use. Family plays an important role in drug abuse prevention and preventive drug abuse programs must be adapted to this population.     

A comparison of the peers method and traditional methodologies, and risk behaviors in studies of the prevalence of drug consumption in a population of female, Chilean students

The present study investigates drug consumption and risk behaviors among female students between 8th and 12th grade in two communities in the city of Santiago, Chile. Based on studies of university populations, we hypothesize that the students' reports of their consumption of licit drugs will tend to be consistent with their actual use of said drugs using two methods to investigate consumption, while their consumption of illicit drugs will be susceptible, and will tend to be under-reported when evaluated through traditional self-report measures. In order to compare the two methods, a cross-sectional study was designed that would compare reported drug consumption, first using the peers method, and then by means of traditional self-report in a group of 350 students. The results show that women's reports of licit drug consumption converge using the two methods, while as earlier suggested, women's illicit drug consumption was found to be under-reported when traditional methodologies were used.     

Unit-price analysis of opioid consumption by monkeys responding under a progressive-ratio schedule of drug injection.

Several reports have indicated that drug consumption in self-administration procedures is a function of the ratio of the instrumental requirement to the dose of drug, a quantity termed unit price. We evaluated three predictions from this unit-price model in a reanalysis of data on opioid self-administration in rhesus monkeys responding under a progressive-ratio schedule (Hoffmeister, 1979). We evaluated whether consumption was inversely related to unit price, and compared the goodness of fit of an equation devised by Hursh, Raslear, Shurtleff, Bauman, and Simmons (1988) to that of a linear model predicting consumption as a function of dose. We also tested whether consumption was constant when the same unit price was comprised of different combinations of dose and instrumental requirement. Consumption declined overall as unit price increased. The equation devised by Hursh et al. and the linear model based on dose fit the data equally well. Drug consumption was not uniform at a given unit price. The analyses suggest limits on the unit-price model as a characterization of drug consumption.     

Faces in the Clouds: A New Theory of Religion (Book)

This study applies the construct of sanctification to college students' perceptions of their bodies. Students (N = 289) completed measures on the extent to which they viewed their bodies as being a manifestation of God (e.g., "My body is a temple of God") and as characterized by sacred qualities (e.g., holy, blessed, sacred). Greater levels of both forms of sanctification were related to higher levels of health-protective behaviors, strenuous exercise, satisfaction with one's body, and disapproval of alcohol consumption as well as to lower levels of illicit drug use, unhealthy eating practices, and alcohol consumption. Viewing the body as having sacred qualities was also related to lower rates of binge eating and illicit drug use.     

Personality scores and licit and illicit substance use

The effects of personality structure on subsequent substance use was examined. Data were collected from 841 men from Zürich questioned twice at the age of 19 and 22 about drug use and personality. Multiple regression and canonical correlation analysis methodology indicated a significant relationship between personality and subsequent substance use. Illicit drug consumption was positively related to the personality scale Depressiveness and negatively to Dominance and Excitability, cigarette consumption correlated with Nervousness and Sociability and alcohol consumption was related to Nervousness, Depressiveness and Sociability. The association of illicit drug use with Emotional Lability decreased when cigarette and alcohol consumption was included in the analysis. The cannabis users described themselves less neurotic than the consumers of alcohol and cigarettes.     

Modulation of Taste Aversions by a Pentobarbital Drug State: An Assessment of Its Transfer Properties

In a drug-discrimination procedure using conditioned taste aversions, a pentobarbital injection signaled a taste–toxin pairing while the vehicle injection signaled the same taste in the absence of the toxin. In transfer tests, drug states transferred control over consumption to other targets. If the training target was a fluid (saccharin), then transfer occurred to other fluids (both novel and familiar) but not to solid food. If the training target was food, then some transfer occurred to novel targets (both fluids and solid food) but not to familiar targets. Control rats revealed that the differential consumption seen during acquisition and during transfer tests was not due to the summation of two simple associations (i.e., drug–toxin and flavor–toxin) but rather reflected conditional control over consumption by the drug state.     

Drugs as instruments: a new framework for non-addictive psychoactive drug use

Most people who are regular consumers of psychoactive drugs are not drug addicts, nor will they ever become addicts. In neurobiological theories, non-addictive drug consumption is acknowledged only as a "necessary" prerequisite for addiction, but not as a stable and widespread behavior in its own right. This target article proposes a new neurobiological framework theory for non-addictive psychoactive drug consumption, introducing the concept of "drug instrumentalization." Psychoactive drugs are consumed for their effects on mental states. Humans are able to learn that mental states can be changed on purpose by drugs, in order to facilitate other, non-drug-related behaviors. We discuss specific "instrumentalization goals" and outline neurobiological mechanisms of how major classes of psychoactive drugs change mental states and serve non-drug-related behaviors. We argue that drug instrumentalization behavior may provide a functional adaptation to modern environments based on a historical selection for learning mechanisms that allow the dynamic modification of consummatory behavior. It is assumed that in order to effectively instrumentalize psychoactive drugs, the establishment of and retrieval from a drug memory is required. Here, we propose a new classification of different drug memory subtypes and discuss how they interact during drug instrumentalization learning and retrieval. Understanding the everyday utility and the learning mechanisms of non-addictive psychotropic drug use may help to prevent abuse and the transition to drug addiction in the future.     

Cocaine addiction and personality: A mathematical model

The existence of a close relation between personality and drug consumption is recognized, but the corresponding causal connection is not well known. Neither is it well known whether personality exercises an influence predominantly at the beginning and development of addiction, nor whether drug consumption produces changes in personality. This paper presents a dynamic mathematical model of personality and addiction based on the unique personality trait theory (UPTT) and the general modelling methodology. This model attempts to integrate personality, the acute effect of drugs, and addiction. The UPTT states the existence of a unique trait of personality called extraversion, understood as a dimension that ranges from impulsive behaviour and sensation‐seeking (extravert pole) to fearful and anxious behaviour (introvert pole). As a consequence of drug consumption, the model provides the main patterns of extraversion dynamics through a system of five coupled differential equations. It combines genetic extraversion, as a steady state, and dynamic extraversion in a unique variable measured on the hedonic scale. The dynamics of this variable describes the effects of stimulant drugs on a short‐term time scale (typical of the acute effect); while its mean time value describes the effects of stimulant drugs on a long‐term time scale (typical of the addiction effect). This understanding may help to develop programmes of prevention and intervention in drug misuse.     

Consumer behaviour in an unregulated market: the satisfactions and dissatisfactions of illicit drug consumption

Here the case of recreational drug consumption by youths in the West of Scotland is applied to evaluate some prevailing models of consumer satisfaction and dissatisfaction (CS/D). The findings suggest dissatisfactory and satisfactory outcomes do not always result in the types of future consumption behaviours proposed by some models of consumer CS/D. Although, as some models of CS/D suggest, satisfactory experiences tended to reinforce the desire to repeat consumption, when consumption was dissatisfactory, users tended to employ several strategies to justify further use. Whereas users attributed positive or pleasurable experiences to the narcotic effect of the substances consumed, dissatisfactory outcomes were attributed to other factors. Users develop sophisticated responses to dissatisfaction, such as deferment and denial. The findings have important implications for some theories and models of CS/D for consumer expectation: in particular, the effect of dissatisfactory experiences on future consumption intentions.

Drogenkonsum und Strafrecht

Drug consumption is a criminogenic factor. Almost all unauthorized contacts with narcotic drugs are punishable by German law. Users and dealers tie up significant resources within the judiciary, which in turn often requires help from psycho-scientific experts. Aiming at those experts, this article imparts basic knowledge of the criminal law on narcotics. Furthermore, it is meant to outline the impact of drug consumption on the assessment of offenders’ criminal responsibility as well as on ordering measures for the prevention of crime and the reformation of offenders from the jurisdictional point of view. Moreover, the article discusses the legal consequences of driving under the influence of drugs. Additionally, requirements for expert opinions on the criminal responsibility of drug addicts are summarised.     

The instrumental rationality of addiction

The claim that non-addictive drug use is instrumental must be distinguished from the claim that its desired ends are evolutionarily adaptive or easy to comprehend. Use can be instrumental without being adaptive or comprehensible. This clarification, together with additional data, suggests that Müller & Schumann's (M&S's) instrumental framework may explain addictive, as well as non-addictive consumption.     

An exploratory investigation into the self-regulatory processes influencing drug driving: Are young drivers more externally regulated?

An upward trend in drug driving has been observed in several countries around the world. Research suggests that younger drivers are more likely to engage in drug driving compared to older drivers. There is also evidence to suggest young drivers differ from older drivers in their capacity for self-regulation. Despite this, research has yet to explore the impact of age on the self-regulatory processes with regard to decisions to drug drive among drug users. A total of 507 Queensland drivers (72.8% female), who reported ever taking an illegal drug, were involved in the research. Participants completed an online questionnaire, which collected demographic and drug consumption information, as well as items assessing the self-regulatory processes influencing drug driving, and drug driving behaviour. Regardless of age, participants reported a tendency towards internalised regulation. However, results suggest that young drivers (aged 18–24 years) feel greater belongingness to people who promote safe transport decisions after taking drugs, compared to drivers aged 25 years and over. Interaction effects revealed that for young drug takers, feeling greater relatedness, along with perceiving competence and importance in planning alternative transport after taking drugs, can be protective against drug driving behaviours. Significant predictors of drug driving were lower relatedness, greater perceived pressure to drug drive, lower effort/importance to plan safe alternatives after taking drugs, being of older age, and greater drug abuse. Counterintuitively, perceiving more options (choice) to take alternative transport after taking drugs also predicted the offending behaviour. The results of this study suggest that enhancing drivers’ competency to make (and value) safe driving decisions is a critical step for road safety.     

Psychopathologische und kognitive Veränderungen unter Rauschdrogen – Relevanz für die strafrechtliche Beurteilung

To properly estimate the effect of drug consumption in the context of criminal responsibility it is important to understand the nature and course of psychopathological alterations whilst under the influence of each particular drug. In addition, it is important to know about the addictive potential of the different street drugs and the pattern of withdrawal symptoms. In this review we are summarizing the existing evidence for the most widely used illegal drugs. We have considered both anecdotal evidence from and systematic surveys within the illegal drug scene as well as the results of experimental research with healthy volunteers. Finally, we evaluate how acute or subacute psychopathological drug effects effect the degree of criminal responsibility.     

Clinical Implications and Methodological Challenges in the Study of the Neuropsychological Correlates of Cannabis,Stimulant, and Opioid Abuse

Chronic consumption of several drugs of abuse (cannabis, stimulants, opioids) has been associated with the presence of neuropsychological impairments in a broad range of functions. Nevertheless, in recent years neuropsychological research on substance abuse has focused on the study of impairments in the executive functions linked to the prefrontal cortex and their influence on the personality, cognitions, and behaviors of the substance abusers. The aim of our review is, first, to summarize the main neuropsychological impairments shown by classic studies, as well as these new discoveries in executive functioning; second, to consider the mediating role of neuropsychological status on treatment outcomes and analyze the impact of these impairments in clinical practice with drug addicts; and third, to review the principal methodological challenges associated with research in the field of the neuropsychology of substance abuse. We also highlight the convenience of intervening in those functions most relevant to the abusers' persistence in consumption and risk of relapse.     

Masculinity, femininity, and psychosocial adjustment in medical students: a 2-year follow-up

As part of a longitudinal study of medical students, relations between masculinity and femininity and psychosocial well-being were investigated over a 21-month interval. Of a class of medical students, 82% (N = 99) completed measures of masculinity and femininity during orientation and, 21 months later, completed a broad array of measures of psychological well-being, interpersonal functioning, humanistic attitudes toward patient care, and alcohol consumption. Hierarchical multiple regression analyses with interaction terms revealed main effects of masculinity on self-esteem, extraversion, and confidence, and main effects of femininity on hedonic capacity, interpersonal satisfaction, sharing of personal problems, and alcohol consumption. Little evidence for additive or balance androgyny formulations was found. Findings for masculinity were consistent with earlier findings from this study and others, but they were weaker in magnitude. Findings for femininity were surprisingly robust and enrich the construct validity of this measure. Measures of impaired mood and of alcohol and drug impairment were also studied in relation to masculinity and femininity. Both variables contribute to the prediction of depressed mood; femininity also contributes to the prediction of drug involvement. Neither scale has sufficient sensitivity or specificity to be used by itself as a test of impairment.     

A comparison of four computer-based telephone interviewing methods: Getting answers to sensitive questions

Interactive voice response (IVR) technology presents a new and promising approach by which to collect accurate data on sensitive topics by telephone interviews. In a national survey of 2, 880 households of alcohol and drug consumption, we compared computer-assisted telephone interviewing (CATI) and IVR with two hybrid methods that combine IVR with CATI. The principal hypothesis was that the self-report rates of sensitive behaviors would be higher for the hybrid and IVR methods owing to greater perceived confidentiality than with CATI. All the methods obtained similar sample demographic compositions. Response rates did not differ significantly between the CATI and the hybrid methods; however, the response rate with IVR was significantly lower. The hybrid and IVR methods obtained significantly higher self-report consumption rates for alcohol and marijuana and significantly higher hazardous drinking scores, as measured by the Alcohol Use Disorders Identification Test (AUDIT).     

about the authors

Cannabis use has undergone a transition from what was once a largely marginal activity to one that is more generally established. Although the practice is both prevalent and tolerated widely, there is still a certain stigma experienced by users and associated risks that they acknowledge. The thesis of normalization suggests that a more nuanced understanding of such deviance is needed. The focus of analysis, accordingly, must shift from looking at types or traits of drug users to the specific circumstances in which a drug is used. Based on interviews conducted with experienced users in Toronto (N = 104), this paper examines the idea of normal cannabis consumption based on users' own perceptions and management of risk.
