I don't think your use of the qualifier "obviously" is quite called for. I also don't think it's reasonable to assume the statement was made by a professional,

I don't think your use of the qualifier "obviously" is quite called for. I also don't think it's reasonable to assume the statement was made by a professional, as you seem to be (correct me if I'm wrong?). The majority of people probably assume blood tests can detect most popularly known drugs when the dosage is high and the sample is collected within a reasonably short time.

No, not a professional in this field - or even close - but with a smidgen of formal education (BA minor in physiological psych). I guess I thought it was "obvious" in the sense that many people routinely face employment-related drug screenings which don't test for these compounds. But yeah, reading my comment again, I think you're right that "obviously" is probably overstating things. I do think that it's probably sadly optimistic to say "I’m pretty sure that we’ll know exactly what he took", unless things have changed since I last studied this material. I hope that there is a conclusion on which psychoactive compound(s) this person ingested; I apologize for my tone.

  I had no idea LSD was difficult to test for; I guess I had some preconceived belief that most regular drugs (including LSD which is not rare) could easily be detected after a few hours of ingestion. It actually surprises me that you can be high as a kite in a hospital and that doctor might not be able to detect what drugs you’re on with blood/puke sample. I don’t actually have anything near medical training!!

    > It actually surprises me that you can be high as a kite in a hospital and that doctor might not be able to detect what drugs you’re on Funny - I have the opposite notion: it amazes me that it is possible, with blood alone, to determine what someone has ingested. I tend to think of digestion and metabolism as a sort of one-way hash function, but apparently it's a fairly weak function, and rainbow tables abound.
