Key Takeaway
Consider that prior recreational drug use is common in children and adolescents with acute behavioural disturbance.

This was a secondary analysis of a randomised, controlled trial involving 348 children and adolescents aged nine to 17 years who presented to Australian Emergency Departments with acute behavioural disturbance. The analysis examined the prevalence of prior recreational drug use as a potential contributing factor. The main result was that 33% (115/348) of the cohort reported prior recreational drug use. Specific substances included cannabis use in 25% (87/348), amphetamines or methamphetamines use in 9% (32/348), and benzodiazepines use in 7% (26/348). No p-values or confidence intervals were reported for these results. Safety and tolerability data were not reported for this secondary analysis. A key limitation is that the study design is observational, so it cannot establish a causal link between drug use and acute behavioural disturbance. The practice relevance suggests that recreational drug use may be a contributing factor to acute behavioural disturbance among children and adolescents presenting to emergency departments.

Researchers analyzed data from 348 children and adolescents aged nine to 17 years who visited Australian emergency departments. These young people were there because they were experiencing acute behavioral disturbance. The team looked back at their medical records to see if they had used recreational drugs before their visit.

The analysis showed that 33 percent of the patients had used recreational drugs. Among these, 25 percent had used cannabis, 9 percent had used amphetamines or methamphetamines, and 7 percent had used benzodiazepines. The study did not report any safety concerns or adverse events related to these findings.

This secondary analysis suggests that recreational drug use may be a contributing factor to acute behavioral disturbance in this age group. Because the study was a secondary analysis of a trial, it cannot prove that drug use caused the behavioral problems. Readers should understand that this is observational data from a specific setting and not a new treatment recommendation.

What this means for you:
One-third of children with acute behavioral disturbance in Australian EDs had used recreational drugs before their visit.

OBJECTIVES: To describe the historical and current use of recreational drugs by a trial cohort of youth presenting to the emergency department (ED) whilst experiencing acute behavioural disturbance (ABD). METHODS: This was a secondary analysis of a randomised, controlled trial comparing medication management of ABD in children and adolescents aged nine to 17 years who were deemed to require oral sedative medication. RESULTS: Recreational drugs were used by 33% of participants any time prior to enrolment (115/348). Cannabis was the most commonly used (87/348, 25%), followed by amphetamines/methamphetamines (32/348, 9%) and benzodiazepines (26/348, 7%). CONCLUSION: Recreational drug use may be a contributing factor to ABD amongst children and adolescents presenting to EDs.
