National Survey of Drug Use and Health (NSDUH)
• Annual survey of the civilian, non-institutionalized population of the United
States aged 12 years old or older
• Presents national estimates of rates of use, numbers of users, and other
measures related to illicit drugs, alcohol and tobacco products
• Self-reported use
• Approximately 67,500 persons are interviewed in NSDUH annually

• Urine testing
– Detects recent use (previous 24-72 hours)
• Oral fluid testing
– Detects recent use (previous 24-48 hours)
• Hair testing
– Detects a pattern of repetitive use (up to 90 days, based on testing proximal
1.5” head hair)

Possible Drivers for Marijuana Positivity Differences
• Oral fluid collections are observed
– Curbs evasive donor behavior
• New collection and testing technology with Oral-Eze®
– Sample adequacy indicator informs collector when there is desired sample volume
– Different/improved buffer preservative solution

In Conclusion
• Drug users tend to work for employers without a drug testing program
• Data from the DTI and NSDUH suggests that drug testing is a deterrent to drug use by
employees and applicants
• DTI data and some media reports suggest that it may be harder to find drug-free
applicants
• Widening gap between oral fluid and urine marijuana positivity
• New oral fluid testing technology may help in identifying more marijuana users
• Hair testing continues to have a positivity rate more than 1.5x higher than urine
• Random positivity in both urine and hair have declined
• Amphetamines positivity continues to increase
• Cocaine positivity continues to decrease
