Outstanding. Here's a comparison of the NTSB Factual Report level vs.
the table.

Acetaminophen (Tylenol): 10.01 (ug/ml, ug/g)
Table: 10-20 ug/ml is therapeutic.
Conclusion: Low therapeutic range

Diazepam (Valium): 0.055 (ug/ml, ug/g)
Table: 0.02-4.00 is therapeutic
Conclusion: Low therapeutic range

Dihydrocodeine (Codine derivative): 0.031 (ug/mL, ug/g)
Table: 0.03-0.25 is therapeutic
Conclusion: Low therapeutic range

Hydrocodone (Vicodin): 0.152 (ug/ml, ug/g)
Table: 0.03-0.25 is therapeutic
Conclusion: Mid therapeutic range

Nordiazepam: 0.094 (ug/ml, ug/g)
Table: 0.1-2.6 is therapeutic
Conclusion: Low therapeutic range (Wikipedia says that this is
a metabolite of Valim)

Everything looks in the therapeutic range, to this layman. I looked for
a list online of which are banned by the FAA, but didn't find one that
addressed anything other than general classes (AOPA has one, but I'm not
a member).
