Objective - To review the ethical and legal implications of the involv
ement of medical practitioners in workplace screening for drug misuse.
Conclusions - Workplace screening for drugs of abuse raises many ethi
cal issues. If screening is considered as being part of medical practi
ce with the involvement of occupational health physicians, as suggeste
d by the Faculty of Occupational Medicine, then the ethical requiremen
ts of a normal medical consultation are fully applicable. The employee
's full and informed consent to the process must be obtained and the e
mployee should have an unfettered right of access to all the relevant
records and to the urine sample he/she has provided in the event that
he/she wishes to challenge the opinion expressed by the physician. If
the process is not part of medical practice then employees should have
the same rights as they would have if required to provide intimate bo
dy samples in the course of a criminal investigation, given the potent
ially serious consequences of an erroneous positive finding for their
livelihood.
