A man from the US died after eating too much liquorice in what is believed to be a medical first.
The 54-year-old builder, from Massachusetts in the US, consumed about one-and-a-half bags of black liquorice every day.
The bizarre case was revealed in the New England Journal of Medicine.
Medics say had suffered no symptoms before suddenly going into cardiac arrest at a fast food restaurant.
In the report, doctors noted that the patient had a poor diet which included an unhealthy amount of sweets.
The authors of the report blamed glycyrrhizic acid - the active ingredient in liquorice - for the fatal reaction.
The chemical compound is known to cause "hypertension, hypokalemia, metabolic alkalosis, fatal arrhythmias, and renal failure" and all of these medical conditions were seen in the patient.
Hypokalemia occurs when a person's potassium levels in their blood become dangerously low.
The reports also stated that the patient had also recently changed the type of sweets he was eating and had switched from red fruit-flavoured twists to another type made with black liquorice.
Dr Andrew L Lundquist, writing in the report, agreed in the report that the liquorice was to blame.
He wrote: "Further investigation revealed a recent change to a liquorice-containing candy as the likely cause of his hypokalemia."
