Anthony Bourdain did not have drugs in his system at the time of his suicide, according to French authorities.

The “Kitchen Confidential” author and host of the CNN food and travel series “Parts Unknown” was found dead in his hotel room in the Alsace region of France on June 8.

French prosecutors had previously said that all indications pointed to suicide by hanging. And on Friday, lead prosecutor Christian de Rocquigny told the New York Times that toxicology tests found no narcotics in Bourdain’s system at the time of his death. The former chef had only a nonnarcotic medication in his system, in a therapeutic dose, the prosecutor reportedly said by text message.

Bourdain was open about his previous battled with drug abuse in his youth, and admitted to being a heroin addict until the 1980s. He said in a February interview with People magazine that he had stopped using illegal drugs some time ago, but continued to drink alcohol in moderation.

In the same interview, Bourdain said he was “happy in ways I didn’t think I ever would be, for sure.”
