How accurate are the blood tests done at hospitals?

My friend crashed their car while they were barred out ( Bliss Bars :) ) a while back, and they said that when they were taken to the hospital, they were told that there was no alprazolam in their system; only barbiturates. (???) I don't see how that could be possible because you would need a much higher dose of much more expensive and harder to find powder than alp in each bar, and with as many as they took, they would have been dead, had the bars actually contained a barbiturate.

And then a few months ago, when I crashed my car while barred out, the blood test showed that I had only marijuanas, heroin, alprazolam, MDMA, and cocaine in my system, but I never did any coke? at least I don't think I did??? Maybe it was in the heroin or something, idk; but these two occurrences seem very odd to me.

Thoughts?

Lol...what is luck? Hypothetical question of course. Is crashing your car while barred out like, a mandatory thing to do in order for the effects to be considered "good"?

I got pulled over high on heroin with heroin in the car.. I passed all the physical eye and walking tests.. but they wanted a blood sample... took me to hospital and months later that dropped my "dui" cause I tested negative for drugs.

You may get lucky!

A lot of blood tests are notoriously unreliable, except for things that are very obvious like alcohol that are present in significant quantities. Even blood tests for diseases and such have appalling false-negative and false-positive rates. In many cases interpreting labs is as much an art as a science.

They're about this accurate. I'm holding my hands about this distance apart.

I imagine your blood test's recollection of what you'd ingested was more-accurate than your own. Are you David Crosby of the Byrds / Crosby Still Nash & Young? That reads just like the toxicology report from when he was arrested.

If you don't know, have a look on your drivers license. Or sing along to Marakesh Express and see which harmony part you pick.

Do you have a surgical scar above your liver, and a handlebar moustache? Or do you have a kind of hybrid British / LA accent, and remember being in the Hollies?
