Drugs of Abuse
Drugs of abuse analysis is only offered as a clinical service
for the treatment of drug dependence or, rarely, in the management
of patients with suspected overdose.
Analysis is not suitable for medico-legal purposes such as child
custody or employment screening. In such cases, independent private
laboratories offer a service that provides 'chain of custody' and
results that are legally defensible e.g. MedScreen 0207 7712 8000 (we do not
recommend any specific laboratory).
Spiked drink analysis: if alleged incident has occurred within
the past 48 hours, a urine sample in a plain (white top) universal
may be sent to the laboratory for storage and the patient should be
advised to contact the police. If the alleged incident is more than
48 hours ago, any drugs that might be used in spiking drinks will
have already been metabolised and excreted so screening is not
worthwhile. However, the patient should still be advised to contact
Amphetamines, benzodiazepines, cannabis, cocaine, opiates,
