Toward advancement in estimating drug use history -hair drug testing-
Disposition of drugs into hair can provide firm evidence and chronological information on individual drug use, which are often indispensable evidence of crimes.

The high-resolution analyses and our findings concerning incorporation pathways present essential information for the advancement of chronological-resolution in estimating drug use history.
