The length of time
for which a drug will remain detectable in urine depends on the rate of drug
excretion in the individual, the quantity and frequency of drug use and the
sensitivity and cut-off levels of the testing procedure.
Most drugs will be
detectable up to 3-5 days and frequency of use may increase the time of
detection. This may indicate that a person is currently using or they may have
ceased using within the time frame of detection. Perhaps have a conversation
with the person you are concerned about.
