Dr. Marilyn Huestis Q & A: Matching Drug Effects to Drug Concentrations

Dr. Marilyn Huestis of NIDA’s Intramural Research Program talks about conducting research on drug effects with human subjects, developing tests to help law enforcement identify drugged drivers, and an assay to help identify children whose prenatal exposure to anti-HIV drugs may put them at risk for adverse developmental outcomes.

Frequently Asked Questions About Drug Testing in Schools

What is drug testing?

Some schools, hospitals, or places of employment conduct drug testing. There are a number of ways this can be done, including: pre-employment testing, random testing, reasonable suspicion/cause testing, post-accident testing, return to duty testing, and follow-up testing. This usually involves collecting urine samples to test for drugs such as marijuana, cocaine, amphetamines, PCP, and opiates.

Workplace Resources

Nearly 75 percent of all adult illicit drug users are employed, as are most binge and heavy alcohol users.1 Studies show that when compared with non–substance abusers, substance-abusing employees are more likely to

  • change jobs frequently
  • be late to or absent from work
  • be less productive employees
  • be involved in a workplace accident
  • file a workers’ compensation claim.

Employers who have implemented drug-free workplace programs have important experiences to share.
