Q: Can secondhand marijuana smoke render a positive drug test?
- There are no published, peer-reviewed studies to date that indicate, even with today’s
increased concentrations of THC in marijuana, that someone would test positive due to
‘passive’ or ‘incidental’ exposure at events such as parties or concerts.”
- The National Institute on Drug Abuse (NIDA) concurs, reporting that it unlikely that secondhand
marijuana smoke could give someone a contact high after examining research that
measured factors such as drug potency, hours of exposure, and room ventilation.
