Abstract
The use of synthetic cannabinoids is being increasingly recognised worldwide, but the chemical compositions and physiological effects of these drugs are poorly characterised and are continually changing. New substances are constantly being added to the content of synthetic cannabinoids and they are rarely identified on toxicological screening tests. Due to their structures synthetic cannabinoids and their effects have been compared to the psychoactive compound, Δ-9-tetrahydrocannabinol (THC), found in marijuana. On the molecular level, they are potent cannabinoid receptor agonists that also may have affinity for other types of receptors such as those on platelets. Reported symptoms of toxicity include anxiety, agitation, paranoia, hallucinations, tachycardia, hypertension, excessive sweating, nausea, and vomiting. They can also be linked to serious adverse cardiovascular events and can affect the cardiovascular system causing hypotension and bradycardia, myocardial infarction, atrial fibrillation, prolonged QTc, and Mobitz type II atrioventricular block, as well as interfere with the aggregation of platelets. We present a case report of a cardiac tamponade with toxicological findings positive for synthetic cannabinoids. This case highlights the importance of testing routinely for novel psychoactive compounds, and recognising their potential to cause life-threatening conditions.File | Dimensione | Formato | |
