A new LC-MS/MS method was developed to simultaneously extract LSD, iso-LSD, 2-oxo-3-hydroxy-LSD, and 1-propionyl-LSD from hair samples. The method was applied to hair from 18 suspected LSD users. Segmental hair analysis showed LSD concentrations decreasing from the proximal to the distal end, while 1 P-LSD was not detected in any hair segments. The authors report concentrations of LSD and iso-LSD in human hair from 18 LSD users, but note that interpreting hair analysis results for LSD remains difficult.
