Frequently Asked Questions

My patient swears they had recently used heroin but the confirmation results came back negative. Are they lying?

Possibly but not necessarily. Heroin has a very quick half-life in the body and the urine collection could have just been outside of the time window to be detected by screen or mass spec analysis. Also, the quality of heroin may have been poor, meaning it was mixed with a cutting compound such as manitol or sodium bicarbonate so it was a smaller amount of heroin used.
