Former Nairobi County Chief Officer Geoffrey Mosiria has broken his silence on allegations that he uses cocaine, dismissing the claims as malicious rumours and insisting that medical tests conducted at Nairobi Hospital found no trace of drugs or other substances in his system.
Speaking in response to the controversy during a discussion linked to the BNN podcast show, Mosiria attributed his recurring nasal congestion to air pollution, explaining that his nose becomes blocked whenever he visits polluted environments. The former county official said his condition had been misunderstood by people spreading allegations about his alleged drug use, maintaining that his experience with air pollution had nothing to do with cocaine.
"Because am a victim of air pollution, whenever i go to a place that is polluted my nose will block, na watu wanaanza kusema ati Mosiria anatumia cocaine," he said.

Mosiria went on to challenge the allegations, arguing that the claims did not reflect the person Kenyans knew.
He maintained that the rumours had caused unnecessary speculation about his personal life, questioning why people would associate his nasal congestion with drug use without considering other possible explanations.
Mosiria Reveals Nairobi Hospital Tests
In his remarks, Mosiria also recounted an incident in which he felt unwell and became concerned that someone might have poisoned him.
He said he rushed to Nairobi Hospital, where he underwent toxicology tests to establish whether there were any harmful substances in his system.
According to Mosiria, the results came back negative, with no cocaine or other substances detected.
"I'm actually happy that the other day nilikuwa naskia vibaya, nilikuwa nafikiria kwamba watu wameniekea sumu nikakimbia Nairobi Hospital nikafanyiwa toxicology wakaangalia kila kitu my results were negative nothing like cocaine," he stated.
He further insisted that neither methadone nor any other substances were present in his system, challenging those spreading the allegations to verify his claims with the hospital.
"So for those people wamelipa bloggers waseme navuta cocaine, let them confirm with my Nairobi Hospital," Mosiria added.

However, the hospital results he referred to have not been independently verified in the remarks available, and the details of the tests have not been publicly established.
Accuses Bloggers of Political Influence
Beyond the drug allegations, Mosiria accused some bloggers of being paid to damage the reputations of public figures through negative publicity.
He suggested that politicians could be behind such campaigns, arguing that some political actors were interested in protecting their own interests while bloggers benefited financially.
"I think the problem is bloggers are paid to paint people in a negative way and they are paid by politicians because politicians ever think of themselves and the bloggers benefit from them," he said.
Mosiria's remarks come as he attracts attention over his reported interest in contesting the Nairobi gubernatorial seat in the 2027 General Election.
His political ambitions have placed him under increased public scrutiny, with his departure from the Nairobi County administration also drawing attention.
The former chief officer's latest comments have added another dimension to the debate surrounding his public image, as he seeks to counter the allegations and challenge those spreading claims about his personal life.
