Overview

• A urine sample taken on June 11 at Fastest Labs of South Austin returned negative results for 22 substances, including ketamine, cocaine, and amphetamines.
• The test directly challenges a New York Times investigation that claimed Musk’s heavy ketamine use led to bladder issues and that he travelled with a daily pill box of some 20 medications.
• Musk has publicly acknowledged trying prescription ketamine years ago for depression but insists he has not used it recently and has called the original report false.
• Drug-testing experts caution that urine assays only detect substances ingested within a few days, leaving longer-term use undetected.
• The episode has reignited debate over Musk’s roughly 130-day stint as head of the Department of Government Efficiency and his highly publicised fallout with President Trump.
