Icelandic customs officers have stopped 199 shipments of melatonin, ordered from the United States. 88 of those shipments were shipped between June and August this year.
Melatonin is a natural hormone that helps control sleep and wake cycles. In various countries, such as the United States, it's sold as a supplement. In Iceland, however, it's classified as a drug and is prohibited from being imported to Iceland.
The Icelandic Directorate of Customs report mentions the INTERPOL 2016 operation, in which Iceland was an active participant, 12.2 million units of illegal and possibly dangerous drugs were seized and 4.932 websites that offered such products were closed. "International operations of this magnitude have confirmed that criminals are limitless when it comes to adulteration and no type of product is excluded, that includes drugs and food supplements,"
The melatonin shipments are currently on their way to the Suðurnes Waste Disposal Station.
