The detection times in urine are significantly greater than detection times in blood, which is also generally much more expensive. The presence of a drug or drugs in urine does not provide information as to whether the individual is actually under the influence at any particular time. Likewise, no determination can be made from urine as to the amount of the dose or the time of the dose.
