Multiple substance use among patients attending treatment for substance-related problems in Switzerland

A Scoping Review of Gender, Sex and Sexuality Differences in Polysubstance Use in Adolescents and Adults

BACKGROUND

Polysubstance use is a common, problematic behavior that increases risk of harm to self and others. Research suggests that rates may vary based on gender, sex and sexuality. Understanding the current state of this literature may inform prevention and treatment of polysubstance use, leading to reduced public health burden.

OBJECTIVES

This review aimed to synthesize research on gender, sex and sexuality differences in polysubstance use in adults and adolescents.

METHODS

A scoping review was conducted using all EBSCO databases, PubMed and Google Scholar to identify articles examining the effects of gender, sex and sexuality on polysubstance use. Polysubstance use was defined broadly as the use of any combination of substances over any time period and included licit (alcohol, tobacco) and illicit substances, concurrent and simultaneous use, from lifetime to daily use and use at any frequency. Studies were considered if they were published in peer-reviewed journals between January 1990 and October 2020 and were written in English. Publicly available data sources were also utilized to fully capture prevalence data that has not been published elsewhere.

RESULTS

Findings were mostly inconsistent and often conflicting. Only two findings were generally consistent: adult men were overall more likely to report polysubstance use than adult women, and sexual and gender minorities report more frequent polysubstance use than non-minorities.

CONCLUSIONS

Research has been unable to clearly elucidate differences in polysubstance use prevalence and patterns according to gender, sex and sexuality. Several recommendations are offered to advance future research and address limitations of current research.

From “Codeine Diet” to “Gutter Water”: polydrug use among Nigerian young adults

Purpose

The purpose of this paper is to explore polydrug use and the factors that motivate the use of multiple substances among selected young adults.

Design/methodology/approach

A total of 23 male and female participants (aged 23-29 years) who use illicit drugs and prescription pharmaceuticals for non-medical purposes were recruited through snowball sampling. Qualitative interviews were conducted, and the data were analysed thematically.

Findings

The use of drug “concoctions” and cocktails was widespread among the participants. Some used what they called Codeine Diet (codeine-based cough syrup mixed with a Coca-Cola® product or malt drink), while others took Gutter Water (a cocktail of cannabis, codeine, tramadol, vodka and juice or water). The use of Monkey Tail (a mixture of local gin, cannabis leaves, stems, roots and seeds) and petrol mixed with glue and La Casera® (carbonated soft drink) combined with Tom-Tom® (menthol-flavoured candy) was also revealed. Pleasure, better highs, the need to experience prolonged intoxication and the use of one drug to douse the effects of another substance motivated polysubstance use.

Social implications

The findings revealed that the reasons why codeine-based cough syrups are mixed with soft drinks (Codeine Diet) include avoiding social discrimination and evading law enforcement agencies. Results suggest that these drug use practices require specifically tailored public health interventions. Social stigmatization against substance users and the use of extra-legal measures by the police should be discouraged to facilitate harm reduction.

Originality/value

This study represents the first qualitative research to explore polydrug use among an understudied Nigerian population.
