Potent Synthetic Cannabinoid 5F-AKB48 Emerged as an Adolescent Drug in France

Retrospective CohortModerate evidence
The takeaway

Between 2017 and 2024, French poison centers recorded 304 cases of 5F-AKB48 exposure, predominantly in adolescent males (median age 16.5), with 4% experiencing severe symptoms including seizures and coma.

What the researchers found

Among 304 cases reported to French Poison Control Centers, the median age was 16.5 years with a male-to-female ratio of 4.4:1. The drug was used alone in 91% of cases. Most (59%) had mild symptoms, 35% moderate, and 4% severe (seizures, coma, agitation). Multiple substance use was associated with more severe outcomes. Most exposures occurred in northern France, and the drug is likely popular due to its compatibility with e-cigarette devices for discreet use.

Why it matters

Synthetic cannabinoids are far more potent and dangerous than plant cannabis, yet they can be consumed discreetly through e-cigarettes, making detection difficult for parents and schools. Their emergence among adolescents represents a distinct public health challenge.

The numbers in context

304 cases; median age 16.5; sex ratio 4.4 M:F; 91% used alone; 59% mild, 35% moderate, 4% severe; severe symptoms: seizures, coma, agitation; no fatalities; predominantly northern France

How the study worked

Retrospective analysis of all acute 5F-AKB48 exposure cases reported to French Poison Control Centers from 2017 to 2024. Assessed demographics, symptoms, and outcomes using the Poison Severity Score.

What this study cannot tell us

Poison control data captures only cases severe enough to prompt a call; actual use likely much higher. Outcome unknown in 36% of cases. Cannot assess chronic health effects. French-specific regulatory and cultural context.

How to read the evidence

Moderate: comprehensive national poison center data over 7 years, but likely underestimates true prevalence.

The bigger picture

Synthetic cannabinoids often surge in use when they are novel and unregulated, then decline as awareness of dangers grows and regulations catch up. The compatibility with e-cigarette devices is a new delivery vector that complicates traditional drug detection.

Questions still open

  • How common is undetected synthetic cannabinoid use in e-cigarettes among adolescents?
  • Would e-cigarette regulation targeting liquid additives reduce synthetic cannabinoid vaping?
