It was during a party in Haninge, the night before Saturday, that the woman was taken to Södersjukhuset after drinking from a beer bottle.
The woman was severely poisoned and unconscious when she came to the hospital and was put on a respirator there.
Several media outlets have previously reported on the incident.
According to Expressen, an analysis has shown that the contents of the bottle were amphetamine base, which is a precursor to amphetamine.
On Monday evening, the news came that the woman's life could not be saved.
The Special Prosecutor's Office has confirmed to the newspaper that a preliminary investigation into the crime has been launched.
This is because it is suspected that the beer bottle, which was traced to the police station in Haninge, may have been stolen from the seizure.
