Blood Drug Testing

how many days can marijuana be detected in a saliva drug test?

my friend has to take a drug test probably tomorow or thursday, and she smoked on saturday, and the time before that was st patricks day. any ideas on if it could still be in her system or not and will be detected through a saliva drug test?

1. depends how often she has used it. If not often it could be out in a week. Drink h20 sweat. heavy users can have it in the system for a month. I took a saliva test and passed after smoking. Perhaps it was my toothpaste?
2. heard it stays in the system for months at a time,plenty of water,sweat, and a lot of prayer,good luck to your friend.
3. itll come up. it takes about 6-8 months to get completely out your system. excpet for hair if they do a hair test EVERYTHINNG will come up DEFINATLY
4. I'm pretty sure the saliva tests only go back 18hrs tops. I've had several friends who have had to take saliva tests before, and they've all passed with flying colors (being some of the biggest pot heads you'll ever meet). I would recommend quiting for atleast a day, but don't worry I think the saliva tests are kind of a joke.
