I have a medical eximination on Wednesday I had 2 cones of marijuana last night and 3 beers how long would it take to leave my urine

So you are not having a medical exam, you are having a urnine test for drugs and alcohol?

Hello - It depends on whether you smoke frequently or not. If you smoke daily, or multiple times daily, marijuana can take a much longer time to leave your system. If a frequent smoker and infrequent smoker quit on Monday, the frequent smoker may have marijuana in their system for anywhere from 30-45 days later, while the infrequent smoker may not have marijuana in their system after a week or two. There are lots of factors that influence how long marijuana stays in your system but frequency of use is a really important one.
