The seizure was made in connection with a major investigation into financial crime and extortion, when police raided the home of a 45-year-old man.
The tablets were found along with 184 grams of powder, making it the largest seizure of the synthetic opioid in Sweden to date. The drug is several hundred times stronger than heroin.
"It could be a grain of salt, and then you've taken an overdose," Erik Lindeman, chief physician at the Swedish Poison Information Center, told TV4 Nyheterna.
In 2024, 30 Swedes died from nitazene overdoses. In the UK, 333 people died from the drug that same year, according to King's College.
