Brief Answer:
Probably not

Detailed Answer:
Hi and welcome.

Well, this test may detect marijuana use within 90 days after consumption. However, if there was no excessive use of them, this may not be detectable, but it is not possible to know for sure about that, so it would be good for you to delay this test as long as possible to reduce risk of positive result.

Wish you good health.
