RESUMO

Recent use of psychoactive substances among 456 medical students throughout the six grades was surveyed by way of a self-report questionnaire using World Health Organisation criteria. Among male medical students, the most frequently used substances were alcohol (80.5%), cannabis (25.3%), solvents (25.2%), and tobacco (25.2%), whereas among female students the most frequently used drugs were alcohol (72.6%), tobacco (14.6%), solvents (10.5%), and tranquillizers (7.5%). Switch from illegal to legal drugs were observed only among female medical students. Male students tend to alternate cannabis and solvents throughout college years. Interventions aiming to influence patterns of drug consumption among medical students must consider both gender differences and evolutional patterns of substance use throughout medical course.

RESUMO

INTRODUCTION: The use of alcohol and other drugs among medical students has been a theme of growing interest and concern on the part of researchers, teaching institutions and medical associations since the decade of the 1960's. OBJECTIVE: Recent use of alcohol, tobacco, tranquillisers, amphetamines, cannabis, organic solvents, and cocaine among 456 medical students was surveyed. METHOD: Assessment was done by means of a self-report questionnaire according to World Health Organisation guidelines. RESULTS: Among medical students, after alcohol and tobacco, cannabis and solvents are the most frequently used psychoactive substances. As such, they were the most deeply analysed drugs in this study. Factors associated with the recent use of cannabis and solvents were established by logistic regression. Living with parents or a companion appeared as a protective factor for the use of cannabis. However, being male and regularly participating in the activities at the campus Sports Association showed as risk factors for the use of both cannabis and solvents. DISCUSSION: Concepts and misconceptions concerning protective and risk factors must be discussed in the light of cultural and circumstantial interferences. Harm reduction strategies should be seriously considered.

RESUMO

INTRODUCTION: Craving for cocaine seems to play an important role in the continued use of and dependence on the substance. AIMS: to describe characteristics of the craving phenomenon in a sample of cocaine users and to identify those that could predict the appearance of the phenomenon. METHOD: 205 cocaine users attending an outpatient clinic were interviewed to assess patterns of drug consumption and characteristics of craving for the drug. FINDINGS: Subjects were mostly young (24.8+/-12.8 years) and male (86.2%). One hundred and two subjects (49.8%) were addicted to cocaine and the remainders (50.2%) were non-addicted occasional cocaine users. The majority of subjects (60.5%) reported having had craving episodes during the previous week. Frequency of cocaine use during the previous month correlated with the number of reported craving fits (r=0.425; p<0.001) and with the duration of the craving fits (r=0.351; p<0.001). Users of crack reported more craving episodes than did the users of snorted cocaine (p<0.001) and the frequency of craving fits was inversely proportional to the duration of abstinence from the drug (r=-0.405; p<0.001). CONCLUSION: Both the method of drug consumption and the abstinence period elapsed since previous drug intake were identified as predictive parameters of craving.

RESUMO

The purpose of the study was to evaluate neuropsychologically adolescents who use ayahuasca in a religious context. A battery of neuropsychological tests was administered to adolescents who use ayahuasca. These subjects were compared to a matched control group of adolescents who did not use ayahuasca. The controls were matched with regards to sex, age, and education. The neuropsychological battery included tests of speeded attention, visual search, sequencing, psychomotor speed, verbal and visual abilities, memory, and mental flexibility. The statistical results for subjects from matched controls on neuropsychological measures were computed using independent t-tests. Overall, statistical findings suggested that there was no significant difference between the two groups on neuropsychological measures. Even though, the data overall supports that there was not a difference between ayahuasca users and matched controls on neuropsychological measures, further studies are necessary to support these findings.

RESUMO

Ayahuasca is believed to be harmless for those (including adolescents) drinking it within a religious setting. Nevertheless controlled studies on the mental/ psychiatric status of ritual hallucinogenic ayahuasca concoction consumers are still lacking. In this study, 40 adolescents from a Brazilian ayahuasca sect were compared with 40 controls matched on sex, age, and educational background for psychiatric symptomatology. Screening scales for depression, anxiety, alcohol consumption patterns (abuse), attentional problems, and body dysmorphic disorders were used. It was found that, compared to controls, considerable lower frequencies of positive scoring for anxiety, body dismorphism, and attentional problems were detected among ayahuasca-using adolescents despite overall similar psychopathological profiles displayed by both study groups. Low frequencies of psychiatric symptoms detected among adolescents consuming ayahuasca within a religious context may reflect a protective effect due to their religious affiliation. However further studies on the possible interference of other variables in the outcome are necessary.

RESUMO

Qualitative research was conducted in Brazil among 28 ayahuasca-consuming adolescents members of the União do Vegetal Church, and 28 adolescents who never used ayahuasca. They were compared on a number of qualitative variables, including vignettes measuring moral and ethical concerns. Psychocultural studies utilizing co-occurences of variables in the realm of qualitative studies are useful in understanding and complementing quantitative studies also conducted among this population. Qualitative data show that the teens in the União do Vegetal religion appear to be healthy, thoughtful, considerate and bonded to their families and religious peers. This study examines the modern use of a powerful hallucinogenic compound within a legal religious context, and the youth who participated in these ayahuasca religious ceremonies (usually with parents and other family members) appeared not to differ from their nonayahuasca-using peers. This study helps to elucidate the full range of effects of plant hallucinogenic use within a socially-sanctioned, elder-facilitated and structured religious context.

RESUMO

Ritual use of ayahuasca within the context of the Brazilian ayahuasca churches often starts during late childhood or early adolescence. Premature access to psychoactive drugs may represent a risk factor for drug misuse. Conversely, religious affiliation seems to play a protective role in terms of substance abuse. The objective of this study was to describe patterns of drug use in a sample of adolescents using ayahuasca within a religious setting. Forty-one adolescents from a Brazilian ayahuasca sect were compared with 43 adolescents who never drank ayahuasca. No significant differences were identified in terms of lifetime substance consumption. Throughout the previous year period, ayahuasca adolescents used less alcohol (46.31%) than the comparison group (74.4%). Recent use of alcohol was also more frequent among the latter group (65.1%) than among ayahuasca drinkers (32.5%). Although not statistically significant, slight differences in terms of patterns of drug use were definitely observed among groups. Despite their early exposure to a hallucinogenic substance, adolescents using ayahuasca in a controlled setting were mostly comparable to controls except for a considerably smaller proportion of alcohol users. Religious affiliation may have played a central role as a possible protective factor for alcohol use. Thus, ayahuasca seems to be a relatively safe substance as far as drug misuse is concerned.
