drugs of abuse test [Design Issues]
❝ [...] for which drugs subject should be screened?
Depending on your expectations on the abuse practice in the local subject recruitment area...
I would recommend benzodiazepines, amphetamine/methamphetamine, cocaine, opiates (+optional methadone), and cannabis.
I would also consider screening for barbiturates obsolete.
