Abuse of cocaine, methamphetamines, opiates and phencyclidine (PCP) may be difficult to detect through traditional urinalysis because these substances are quickly excreted from the body. They’re usually undetectable 72 hours after consumption. Our hair testing procedures solve that problem! We can detect use of these drugs as much as 90 days after the person has used them. And, because the test is done on the hair shaft itself, there is no opportunity for the applicant or employee to falsify or adulterate the sample. We can perform this effective, accurate test to identify drug users in your workplace!
