Marijuana remains the most abused drug in the United States. A recent SAMHSA report shows that 76% of drug users self report they use marijuana. Without the proper test methods and technology, marijuana poses some unique challenges and is difficult to test in hair.
While other labs hair tests may find no additional marijuana users than urinalysis tests (and often find less), Psychemedics' hair test typically detects 4 to 7 more times the number of marijuana users than urinalysis. Overall, Psychemedics detects 5 to 10 times the number of drug users for all drug categories tested, when compared to urinalysis in paired data. With a Psychemedics hair test you can be confident in not only superior detection of marijuana, but superior detection of drug abuse across all drug categories.
So remnant metabolites prove abuse of drugs.... clowns, all of them!
