Several prominent Turkish figures were summoned for questioning and blood tests on Wednesday as part of a drug-related investigation, according to prosecutors.
The investigation, led by the Istanbul chief prosecutor, was launched against individuals suspected of "using narcotic or stimulant substances," the prosecutor's office said.
Those summoned by prosecutors include 19 public figures, including singers, actors, television personalities and social media influencers.
These characters were expected to be released after blood tests were conducted and statements were given, with prosecutors not planning any arrests or charges at this stage, local media reported.
Turkish law on drug use gives authorities the ability to order treatment, rehabilitation, or parole conditions instead of prison in cases involving personal use.
Hundreds of people were detained in the largest drug operation in Ankara, the interior ministry said.
This investigation comes at a time when a broader crackdown on artists and opposition voices is underway under the administration of President Recep Tayyip Erdoğan.
Turkish pop singer Mabel Matiz is currently facing up to three years in prison on charges of "indecency" in the lyrics of one of his songs. Prosecutors claim the song violates laws on public morality.
Girl group Manifest is also facing legal action over allegations of "indecent acts" during a recent performance.
More broadly, Turkey has intensified efforts to combat drug use and trafficking in recent years.
In April, Turkish police detained 525 drug trafficking suspects in the capital Ankara, in what the government called the "largest narcotics operation" in the country's history.
