Does niacin clean pcp out your system in 15 hours?

Niacin, also known as vitamin B3, does not clean PCP (phencyclidine) out of the body within 15 hours or any specific timeframe. PCP is primarily eliminated through the liver and kidneys, and the rate of elimination can vary depending on factors such as the amount and frequency of use, metabolism, hydration status, and overall health. Niacin, on the other hand, does not have a specific role in directly clearing PCP from the system.
