The recent release of a toxicology report has revealed that American chess grandmaster Daniel Naroditsky had multiple drugs in his system at the time of his untimely death.

At just 29 years old, Naroditsky’s body was discovered by fellow grandmaster and friend Oleksandr Bortnyk. Bortnyk found Naroditsky unresponsive on his couch at his Charlotte, North Carolina home on October 19, after going to check on him.

Following the discovery, police informed the Daily Mail that they were considering the possibilities of suicide or an accidental overdose, as there was no evidence pointing to foul play or criminal involvement.

An in-depth report from the North Carolina Office of the Chief Medical Examiner, which was obtained by NBC News, confirmed the presence of methamphetamine, amphetamine, 7-hydroxymitragynine, and mitragynine in Naroditsky’s system at the time of his death.

While methamphetamine and amphetamine are synthetic stimulants, 7-hydroxymitragynine and mitragynine are active compounds found in Kratom, a Southeast Asian plant known for its opioid-like effects.

All of the drugs found in Naroditsky’s system have potential for addiction, according to the Drug Enforcement Administration (DEA). 

Methamphetamine is a Schedule II controlled substance, which means the federal government has deemed it as having a high potential for abuse and dependence, with some highly restricted but accepted medical applications. 

Kratom is not a controlled substance, though the DEA has listed it as a Drug and Chemical of Concern, saying that regular consumption ‘can lead to psychotic symptoms, and psychological and physiological dependence.’

Over the course of the year before Naroditsky died, he was repeatedly accused of cheating in online chess games by 50-year-old Russian chess grandmaster Vladimir Kramnik.

Kramnik claimed that Naroditsky was using ‘chess engines,’ which are computer programs that generate moves regarded as the strongest in a given scenario, for online games.

The American grandmaster, who was world champion from 2000 to 2006, had repeatedly denied Kramnik’s allegations.

The cheating accusations caused Naroditsky stress and emotional struggles, according to his mother, Elena Naroditsky, who spoke to the Daily Mail in October. 

‘There was nothing more important to Daniel than his dignity and his name as a chess player,’ the mother said. 

‘Daniel tried to defend himself so much,’ she continued. ‘The whole world was on Daniel’s side. He played more and did more and more because he was trying to prove that he’s not what he was accused of.’

Naroditsky’s mother also told the Daily Mail that her son had been planning on visiting his family in the Bay Area the week after he died, as well as celebrate his birthday on November 9, indicating that the overdose was accidental.

The mother described her son as ‘so brilliant, so incredibly kind and loving, thoughtful, giving, inspiring.’

Kramnik was widely attacked for making his accusations after Naroditsky’s death. In response, the Russian shared a post on X that said: ‘Without a doubt, this recent tragedy should be investigated by police.

‘There are too many huge financial interests involved to be sure about it being just an incident. I am ready to provide all information required.’

Naroditsky had a large online following, with around 500,000 subscribers on YouTube and north of 300,000 followers on the livestreaming platform Twitch. He posted educational chess content on both platforms. 

In Naroditsky’s final livestream, he described the toll the cheating accusations had on him.

‘Unfortunately, ever since the Kramnik stuff, I feel like if I start doing well, people assume the worst of intentions,’ he said. ‘The issue is the lingering effect of it.’

Naroditsky previously said that Kramnik was trying to ‘destroy my life’ and inflict ’emotional and physical harm’.

He also said that the sustained and constant nature of the ‘delusional’ accusations was an ‘evil and absolutely unhinged attempt to destroy my life.’

‘I’m tired of mincing words, he is trying to ruin my life, trying to inflict emotional harm, physical harm on me. He knows exactly what he’s doing, and this is one of the most wicked people I have ever dealt with,’ Naroditsky said.

Naroditsky was a child prodigy who achieved the highest chess title at the age of 18 

On Tuesday, Kramnik issued a public statement that said the loss of Naroditsky was a tragedy for his family and the entire chess community. 

The statement also said that a smear campaign has unjustly tied Naroditsky’s death to the Russian, who has received death threats directed at him and his family. 

Naroditsky was a child prodigy who achieved the highest chess title at the age of 18. 

The young grandmaster maintained a top 25 ranking throughout his adult career, and he won the US National Blitz Championship shortly before he died.
