Brief Answer:
It is unlikely to show with urine test

Detailed Answer:
Hello,
Thanks for using healthcaremagic.

For a single time intake it is unlikely to show in urine test after three days of marijuana intake. But in case you had repeated earlier exposure (even passively) it may remain in the system for two to four weeks.

If the scheduled drug test will get hair sample it may be detected upto three months.

I hope you are scheduled for urine test and you do not have early exposure so get assured that it will be negative test.
Hope I am able to answer your concerns.
If you have any further query, I would be glad to help you.
If not, you may close the discussion and if possible you may rate the answer for me, so that I get a good feedback.
Thanks and regards
Dr Ashok Kumar
