A systematic review of research on illicit substance use and a meta-analysis of its prevalence among college students in Türkiye

In this study, we attempted to systematically review and meta-analysis the prevalence and risk factors for illicit substance use (ISU) in Türkiye. Based on the PRISMA 2020 statement and checklist, we considered only full-text research articles on ISU among college students (CS) in Türkiye. We searched relevant research via Web of Science, PubMed, MEDLINE, Scopus, ScienceDirect, Google Scholar, and ULAKBIM between 11.06.2022-12.31.2022. We applied double arcsin transformation to the prevalence values and used the LFK index and trim and fill method to measure publication bias. In addition, we generated doi and funnel plots of the prevalence values reported in the selected studies. Among systematically reviewed 53 studies, we identified and meta-analyzed ISU prevalence in 37 studies. The mean prevalence of ISU was determined to be 0.06 (95% CI: 0.04 to 0.07). We discovered that cannabis was the most commonly used substance, with an aggregate prevalence rate of 0.044 (95% CI: 0.026 to 0.066). Common risk factors for ISU were found to be gender, parental education, income, mental problems/suicide/attempted suicide, ISU in family members/relatives, smoking, and alcohol use. Despite the lower prevalence of ISU among students in Türkiye, the research findings emphasized that it has recently become a significant public health problem among the young.

Efficacy of an expanded preoperative survey during perioperative care to identify illicit substance use in teenagers and adolescents

BACKGROUND

As illicit substance use can present several perioperative concerns, effective means to identify such practices are necessary to ensure patient safety. Identification of illicit substance use in pediatric patients may be problematic as screening may rely on parental reporting.

AIMS

The current study compares answers regarding use of illicit substances between a survey completed by the patient and the preoperative survey completed by parents or guardians.

METHODS

The study included patients presenting for surgery at Nationwide Children's Hospital, ranging in age from 12 to 21 years. After consent, patients completed a survey of six drop-down questions using an iPad. The six questions involved the patient's history of alcohol, tobacco, marijuana, vaping, and opioid use. The results were compared to the answers obtained from the parents during a preoperative phone call.

RESULTS

The study cohort included surveys from 250 patients with a median age of 16 years. Survey data showed a statistically higher reporting of substance use or abuse from the patient study survey in comparison to the routine parental preoperative survey. Alcohol report rates were highest with 69 (27.6%) patients reporting use compared to only 5 parental reports (2%). There was a similar discrepancy in reported rates of vaping use (40 patient reports, 16.0% vs. 11 parental reports, 4.4%) and illicit substance use including marijuana (52 patient reports, 20.8% vs. 11 parental reports, 4.4%). Reported rates of tobacco use were lowest among the survey responses with 12 patient reports (4.8%) and 5 parental reports (2.0%).

CONCLUSIONS

Identifying illicit substance and tobacco use via a phone survey of parents is inaccurate and does not allow for proper identification of use of these substances in patients ≤21 years of age presenting for surgery. An anonymous 2-min survey completed by the patient more correctly identifies these issues.

Leaving Their Drugs at the Gate? Exploring Changes in Drug Use From Before to During Incarceration in Norway

As the number of incarcerated persons who use drugs increases in many countries, it is important to understand the nature of drug use in prison by exploring how substance use patterns change from before to during incarceration. In this study, we rely on cross-sectional, self-report data from The Norwegian Offender Mental Health and Addiction (NorMA) study to identify the nature of changes in drug use among incarcerated respondents who reported having used either narcotics, non-prescribed medications, or both, during the 6 months before their incarceration (n = 824). Results show that about 60% (n = 490) stop using drugs. Of the remaining 40% (n = 324), about 86% changed their use patterns. Most commonly, incarcerated people stopped using stimulants and started using opioids; switching from cannabis to stimulants was the least common change. Overall, the study illustrates that the prison context leads most individuals to change their use patterns, some in unanticipated ways.

Co-occurring Mental Disorders in Transitional Aged Youth With Substance Use Disorders - A Narrative Review

Adolescence and emerging adulthood are often referred to as youth. Transitional psychiatry addresses this target group, which considers patients between 15 and 25 years of age. Substance use usually begins and peaks at this stage of life. Psychiatric disorders, foremost attention-deficit/hyperactivity disorder, and affective disorders, conduct disorders, and first-episodes psychosis frequently appear in early life stages. This review aims to provide a broad overview of transitional-aged youth's most common psychiatric comorbidities with substance use disorders. A literature search was conducted in Embase and Pubmed, and the main findings are described narratively. We present main findings for the following comorbidities: attention-deficit/hyperactivity disorder, conduct disorder, personality disorders, affective disorders, psychotic disorders, and the phenomena of overdose and suicidality. In conclusion, co-occurring mental health disorders are common and appear to facilitate the development of substance use disorders and exacerbate their overall course. Substance use also affects the severity and course of comorbid psychiatric disorders. Overall, data on transition-age youth with substance use disorders are highly inconsistent. Universal screening and treatment guidelines do not yet exist but should be aimed for in the future.

Intimate Partner Violence and Illicit Substance Use Among Sexual and Gender Minority Youth: The Protective Role of Cognitive Reappraisal

Sexual and gender minority youth (SGMY) disproportionately experience intimate partner violence (IPV) and report illicit substance use compared with cisgender heterosexual youth. Cognitive reappraisal strategies have been shown to decrease trauma-exposed individuals' likelihood of engaging in substance use. However, virtually no research has examined the relationship between various forms of IPV, including identity abuse, and illicit substance use, as well as the protective role of cognitive reappraisal among IPV-exposed SGMY. The current study addressed these limitations and examined cognitive reappraisal as a moderator of the associations between various IPV forms and illicit substance use among 149 SGMY (ages 18-25; 28.9% bisexual, 42.3% transgender or gender nonbinary, 45.0% racial and ethnic minority) between 2016 and 2017. Results indicated that many SGMY used cocaine in the past 6 months (24.8%), followed by hallucinogens (24.8%), stimulants (22.8%), and heroin (20.8%). More than half (62.4%) of SGMY experienced psychological abuse, 44.3% physical abuse, and 43.6% identity abuse in the past year. Cognitive reappraisal buffered the associations between two forms of IPV, identity abuse and physical abuse, and illicit substance use among SGMY, underscoring its importance for clinical intervention. Specifically, past year identity abuse and physical abuse were associated with greater illicit substance use only for SGMY with lower cognitive reappraisal, not for youth with higher cognitive reappraisal. This study adds to the burgeoning literature on identity, physical, and psychological forms of IPV and illicit substance use among SGMY. Our findings provide evidence that cognitive reappraisal strategies buffer the effect of identity abuse and physical abuse on illicit drug use among SGMY. These findings shed light on new avenues for clinical intervention that may help to reduce the prevalence of illicit substance use among IPV-exposed SGMY.

Illegal substance use among 1,309 music festival attendees: An investigation using oral fluid sample drug tests, breathalysers and questionnaires

AIMS

Illegal substance use at music festivals is less documented than it is in nightlife and electronic dance music settings. This study investigated such use through questionnaires, breathalysers and oral fluid drug testing. We also examined the associations between testing positive for illegal substances and demographics, self-reported substance use and measured blood alcohol concentration levels.

METHODS

A cross-sectional study of 1,309 festival attendees from six Norwegian music festivals taking place between July and August 2016. Logistic regression models estimated the likelihood of a positive oral fluid drug test. Covariates were male, age, education, employment, smoking status, early age for alcohol intoxication, alcohol intoxication ⩾2 times a week, past-month and past-year illegal substance use, blood alcohol concentration levels and festivals.

RESULTS

Overall, 12% reported illegal substance use in the past 30 days and 11% tested positive for illegal substances. Cannabis (6%), cocaine (3%) and MDMA/ecstasy (2%) were most commonly detected. One-third had a blood alcohol concentration ⩾0.10%. Of those with a positive test result ( n=146), 95% had detectable alcohol levels and 41% had a blood alcohol concentration above 0.10%. Those studying or working part-time were less likely to test positive compared to those who were not employed. Furthermore, those reporting daily smoking and past-year cannabis or MDMA/ecstasy use were more likely to test positive, compared to those not reporting such use.

CONCLUSIONS

Illegal substance use was less prevalent than in previous nightlife and electronic dance music studies. Almost all those testing positive for illegal substances had detectable alcohol levels and 41% had a blood alcohol concentration greater than 0.10%, possibly indicating combined use.

Exploring Relationships between Recurrent Binge Eating and Illicit Substance Use in a Non-Clinical Sample of Women over Two Years

(1) Background: With the new edition of the Diagnostic and Statistical Manual of Mental disorders, 5th Edition (DSM-5), numerous parallels have been drawn between recurrent binge eating (RBE) and substance use disorders, with many authors examining RBE or binge eating disorder (BED) as a “food addiction”. The present study aims to clarify the relationship between recurrent binge eating (RBE) and illicit substance use (ISU) through investigating the temporal association between the two problems. (2) Methods: This study was embedded within a larger longitudinal study of non-clinical adult women recruited from Australian tertiary institutions. Participants responded at year 2 and year 4 of follow-up to the Eating Disorder Examination—Questionnaire. ISU was measured using a modified questionnaire taken from the Australian Longitudinal Study on Women’s Health. (3) Results: RBE and ISU co-morbidity was 5.88% in this non-clinical sample, and having one condition increased the likelihood of the other. The two conditions had a different trajectory over two years whereby ISU participants had significant risk of developing RBE in addition to or in place of their ISU but the reverse was not found for RBE participants. (4) Conclusion: This unidirectional relationship suggests that in spite of the similarities of RBE and ISU they may be distinct with respect to their co-morbidity over time.

Benefits of universal intervention effects on a youth protective shield 10 years after baseline

PURPOSE

An earlier randomized controlled study found that a universal, family-focused preventive intervention produced protective shield effects-reduced adolescent exposures to illicit substance opportunities-among adolescents in grade 12. This study examined a follow-up assessment of the sample during young adulthood.

METHODS

A randomized controlled trial evaluated the Iowa Strengthening Families Program that was implemented in 22 rural schools (N = 446 families) when the participants were in grade six. Measures included adolescent exposure to illicit substance use and young adult lifetime substance use (age 21; N = 331). Growth curve modeling examined indirect intervention effects through growth factors of adolescent exposure.

RESULTS

Findings from this study confirm protective shield effects that mediate long-term reduction of illicit substance use (β = -.14, p = .02, Relative Reduction Rate = 28.2%).

CONCLUSIONS

The benefits of decreasing exposure to substance use during adolescence through universal interventions were supported, with positive effects extending into young adulthood.

Illicit substance use in pregnancy - a review

Illicit substance use is not uncommon in women of childbearing age. The direct effects of illicit substance use on the mother, pregnancy and the fetus are not well understood, in contrast to the indirect effects of social disadvantage and intercurrent medical and psychiatric illness, which are well documented. We have undertaken a review of the current literature regarding the effects of illicit substance use in pregnancy and include a suggested approach to identification and management of at-risk women.
