Résumé :
Aims: Recently, several synthetic cannabinoids were identified in herbal mixtures consumed as recreational drugs alternative to cannabis products. The aim was to characterize the acute toxicity of synthetic cannabinoids as experienced by emergency patients.
Design: This was a retrospective study targeting patients seeking emergency treatment after recreational use of synthetic cannabinoids.
Setting and participants: Patients were selected from the database of the Poisons Information Center Freiburg between September 2008 and February 2011. The inclusion criteria were: hospitalization, available clinical reports and analytical verification of synthetic cannabinoid uptake. In total, 29 patients were included (age 14-30 years, median 19; 25 males, four females).
Measurements: Clinical reports were evaluated and synthetic cannabinoids and other drugs were determined analytically.
Findings: CP-47,497-C8 (one), JWH-015 (one), JWH-018 (eight), JWH-073 (one), JWH-081 (seven), JWH-122 (11), JWH-210 (11), JWH-250 (four) and AM 694 (one) were quantified in blood samples. JWH-018 was most common in 2008-9, JWH-122 in 2010, and JWH-210 in 2011. Tachycardia, agitation, hallucination, hypertension, minor elevation of blood glucose, hypokalaemia and vomiting were reported most frequently. Chest pain, seizures, myoclonia and acute psychosis were also noted.
Conclusions: There appears to have been an increase in use of the extremely potent synthetic cannabinoids JWH-122 and JWH-210. Acute toxic symptoms associated with their use are also reported after intake of high doses of cannabis, but agitation, seizures, hypertension, emesis and hypokalaemia seem to be characteristic to the synthetic cannabinoids, which are high-affinity and high-efficacy agonists of the CB1 receptor. Thus, these effects are due probably to a strong CB1 receptor stimulation.
KEY FINDINGS:
In Germany, there appears to be an increase in use of some extremely potent synthetic cannabinoids. Acute toxic symptoms associated with their use include agitation, seizures, hypertension, vomiting, and low blood potassium.
