Hi Dear

Welcome to Health Care Magic Team.

Understanding your concern.
To be on safer side you should avoid test within 12 hours after taking THC. .Although there are many factor which can determine how long THC going to stay in saliva like frequency of dose and amount of dose .

It start decreasing after 12 hour in case of saliva and stay upto 24 hours . In case of urine and hair it stays for longer period. Still it depends on person to person as it depends on body tolerance as well.

So i would like to suggest to not to use any narcotics such as marijuana atleast 24 hr before your test.

Hope your concern has been resolved..
Best Wishes,
Dr.Harry Maheshwari
