Further extraction check of drugs from the patch is required, but analyses are manual relatively easy because the chemical composition of sweat nights is simple compared with that of blood or urine.
The sweat procedure residues were analyzed for cocaine and ideal heroin.

Until recently, the use of sweat for drug testing has been hampered by difficulties in sample recovery and by the limited sensitivities edition of analytical methods ( 6 ).
